Set the operation stop time to stop the machine operation within the power suppression unit time. The room temperature adjustment operation planning unit (111) is one of a unit time preceding the power suppression unit time and a unit time following the power suppression unit time, and the unit time for which the amount of power demand is equal to or less than the threshold is set to room temperature. Power consumption in room temperature adjustment unit time, which is extracted as adjustment unit time and makes the air conditioner perform an offset operation to cancel the room temperature change in the power suppression unit time due to the stop of the air conditioner operation. The amount is set within room temperature adjustment unit time in a range where the amount is maintained below the threshold value.

Description

  The present invention relates to generation of an air conditioner operation plan that takes into account the amount of power demand (hereinafter also simply referred to as demand power).

Conventionally, techniques for suppressing peak power have been developed.
The peak power is the maximum demand power amount in an arbitrary period (for example, one day).
One of the methods for suppressing the peak power is a peak shift technique.
In the peak shift technique, as shown in FIG. 32, precooling or preheating is performed before peak power, and the air conditioner is stopped at the time of peak power, thereby suppressing peak power while maintaining comfort.

In the technique of Patent Document 1, the time at which peak power is reached is predicted from room temperature and outside air temperature data, and at a time that is a certain time later than that time, the set temperature is lowered (pre-cooling) during cooling and high during heating (pre-heating). )
As a result, even if the air conditioner is stopped at the time when peak power is reached, the room temperature is low in advance during cooling and high during heating, so peak power can be suppressed while reducing comfort. ing.
Further, in the technique of Patent Document 1, a precooling time required to lower the amount of heat supplied from the air conditioner to a predetermined room temperature or a preheating time required to increase to a predetermined room temperature is calculated. The comfort is maintained by changing the room temperature within a range determined as in FIG.

JP-A-10-197027

However, in the technique of Patent Document 1, precooling / preheating is performed in a unit time one time before a unit time in which peak power is generated.
And the electric power of one unit time is suppressed based on the precooling / preheating effect.
As a result, as shown in FIG. 32, when the demand power in the unit time before and after the unit time in which the peak power is generated (hereinafter referred to as the adjacent unit time) is large, the demand power in the adjacent unit time increases due to precooling / preheating.
As a result, there is a problem that the demand power in the adjacent time becomes larger than the demand power in the unit time in which power suppression is performed, and a new peak power is generated.

  In addition, since only the demand power for one unit time at which the peak power is generated can be suppressed, there is a problem that it cannot be suppressed even if the demand power for the unit time immediately after the peak power is high as shown in FIG.

  The main object of the present invention is to solve the above-mentioned problems, and more reliably suppress peak power by peak shift while maintaining comfort without causing new peak power in adjacent unit time. The main purpose is to do.

An information processing apparatus according to the present invention includes:
A power demand prediction unit that predicts the amount of power demand when the air conditioner normally operates, per unit time;
A unit time when the demand power amount exceeds the threshold is extracted as a power suppression unit time, and the air conditioner is stopped so that the demand power amount in the power suppression unit time is suppressed to the threshold value or less. A power suppression operation planning unit that sets the time within the power suppression unit time; and
One of the unit time preceding the power suppression unit time and the unit time following the power suppression unit time, wherein the unit time for which the demand power is equal to or less than the threshold is extracted as the room temperature adjustment unit time, A canceling operation time for causing the air conditioner to perform a canceling operation for canceling a change in room temperature in the power suppression unit time due to the stop of the operation of the air conditioner, and a demand power amount in the room temperature adjustment unit time is the threshold value And a room temperature adjustment operation planning unit that is set within the room temperature adjustment unit time as long as it is maintained as follows.

In the present invention, the operation of the air conditioner is stopped in the power suppression unit time to suppress the demand power amount of the power suppression unit time below the threshold, and the room temperature change due to the operation stop of the air conditioner in the power suppression unit time The air conditioner is caused to perform the offset operation within the room temperature adjustment unit time within a range in which the amount of power demand in the room temperature adjustment unit time is maintained below the threshold value.
For this reason, according to the present invention, peak power can be more reliably suppressed by peak shift while maintaining comfort without generating new peak power in adjacent unit time.

The weather information storage unit 102, the operation result storage unit 104, and the received power storage unit 106 are not necessarily required for the control device 100.
For example, when a storage device external to the control device 100 stores weather record data, weather forecast data, etc., the control device 100 includes a weather information storage unit 102, an operation record storage unit 104, and a received power storage unit 106. It does not have to be.
Further, when the thermal characteristic calculation unit 107, the thermal load calculation unit 108, and the demand power prediction unit 109 can collect necessary data at once, the weather information storage unit 102, the operation result storage unit 104, and the received power are stored in the control device 100. The storage unit 106 may not be included.

  The thermal characteristic calculation unit 107 calculates the building from the past (before the present time) weather result data stored in the weather information storage unit 102 and the past air conditioner operation results stored in the operation result storage unit 104.

The thermal load calculation unit 108 calculates the transition (time series data) of the thermal load from the weather forecast data for the control target period stored in the weather information storage unit 102 and the thermal characteristics input from the thermal characteristic calculation unit 107. To do.
The thermal load calculation unit 108 uses not only the thermal load when the room temperature is maintained at the normal room temperature during normal operation as the time series data of the thermal load, but also when the room temperature changes due to precooling or preheating. The transition of heat load is also calculated.

The demand power prediction unit 109 includes past weather results data stored in the weather information storage unit 102 and weather forecast data for the control target period, past operation results of the air conditioner stored in the operation result storage unit 104, Based on the past received power data stored in the received power storage unit 106, the received power for each unit time of the control target period is predicted.
That is, the demand power prediction unit 109 predicts the amount of power demand of a facility such as a building when the air conditioner is normally operating for each unit time.
Normal operation is an operation mode for setting the temperature of the room (space) of a facility such as a building to a set temperature.
The user of the control device 100 arbitrarily determines what type of operation mode is the normal operation.
Note that the processing of the power demand prediction unit 109 corresponds to an example of power demand prediction processing.

The power suppression operation planning unit 110 uses the thermal characteristics calculated by the thermal characteristic calculation unit 107, the time series data of the thermal load calculated by the thermal load calculation unit 108, and the demand power of each unit time predicted by the demand power prediction unit 109. Thus, the unit time for suppressing the demand power is determined.
Note that the power suppression operation planning unit 110 may suppress the demand power in a plurality of unit times instead of one unit time so that the peak power can be suppressed even if there are a plurality of unit times with high demand power.
Each unit time that is a target of demand power suppression is referred to as power suppression unit time.
A set of power suppression unit times is referred to as a power suppression period.
In addition, the power suppression operation planning unit 110 calculates the length of time during which the operation of the air conditioner is stopped in each power suppression unit time (hereinafter referred to as “operation stop time”), and creates an operation schedule for the power suppression period.
The power suppression operation planning unit 110 determines the length of the operation stop time in each power suppression unit time so that the demand power of each power suppression unit time becomes equal by power suppression due to the operation stop of the air conditioner.
Further, the power suppression operation planning unit 110 can suppress the demand power (peak power) during the power suppression period most using the precooling / preheating effect (room temperature changed from the normal time) accumulated during the precooling / preheating period. Determine the length of the shutdown time.
The power suppression operation planning unit 110 also calculates the peak power after power suppression and the room temperature to be changed before the start of the power suppression period based on the created operation schedule for the power suppression period.
Moreover, the process of the power suppression operation plan unit 110 corresponds to an example of a power suppression operation plan process.

The room temperature adjustment operation planning unit 111 includes thermal characteristics calculated by the thermal characteristic calculation unit 107, time series data of the thermal load calculated by the thermal load calculation unit 108, demand power and power for each unit time predicted by the demand power prediction unit 109. The unit time for precooling / preheating is determined based on the peak power after power suppression calculated by the suppression operation planning unit 110 and the room temperature to be changed by the power suppression period.
The room temperature adjustment operation planning unit 111 pre-cools / pre-heats a plurality of unit times instead of one unit time so that the demand power does not exceed the peak power after power suppression by pre-cooling / pre-heating. Sometimes.
As will be described later, the room temperature adjustment operation planning unit 111 may plan follow-up cooling / follow-up heating for cooling / heating after the power suppression period instead of pre-cooling / pre-heating.
Each unit time subject to such room temperature adjustment control (pre-cooling / pre-heating, follow-up cooling / follow-up heating) is referred to as a room temperature adjustment unit time.
A set of room temperature adjustment unit times is called a room temperature adjustment period.
The room temperature adjustment operation planning unit 111 is configured so that the power demand of each room temperature adjustment unit time does not exceed the power demand of the power suppression unit time and can be changed to the room temperature determined by the start of the power suppression period. The time of the precooling operation / preheating operation performed at each room temperature adjustment unit time is also calculated.
When planning the follow-up cooling / follow-up heating, the room temperature adjustment operation planning unit 111 normally sets the room temperature after the power suppression period without the demand power of each room temperature adjustment unit time exceeding the power demand of the power suppression unit time. In order to return to room temperature, the time of follow-up cooling / follow-up heating performed at each room temperature adjustment unit time is calculated.
The pre-cooling operation / pre-heating operation (or follow-up cooling / follow-up heating) is an operation for offsetting a change in room temperature due to the operation stop of the air conditioner during the power suppression period, and is also referred to as an offset operation.
Therefore, the time of the pre-cooling operation / pre-heating operation (or the follow-up cooling / follow-up heating) in the room temperature adjustment unit time is also referred to as an offset operation time.
In the offset operation, the power consumption of the air conditioner is larger than that in the normal operation.
The process of the room temperature adjustment operation plan unit 111 corresponds to an example of the room temperature adjustment operation plan process.

  The operation schedule generation unit 112 generates an operation schedule for the control target period based on the operation schedule for the power suppression period planned by the power suppression operation planning unit 110 and the operation schedule for the room temperature adjustment unit time planned by the room temperature adjustment operation planning unit 111. To do.

  Here, the power suppression operation planning unit 110 will be described in more detail.

The power suppression operation planning unit 110 extracts a unit time in which the demand power amount exceeds the threshold as the power suppression unit time.
More specifically, the power suppression operation planning unit 110 extracts the maximum demand power amount from the demand power amount predicted by the demand power prediction unit 109, and subtracts the specified value from the extracted maximum demand power amount. The amount of power demand obtained is set as a threshold value.
Then, the power suppression operation planning unit 110 extracts a unit time in which the demand power amount predicted by the demand power prediction unit 109 exceeds the threshold as the power suppression unit time.

Moreover, the power suppression operation planning unit 110 sets the operation stop time during which the operation of the air conditioner is stopped within the power suppression unit time so that the demand power amount in the power suppression unit time is suppressed to a threshold value or less.
More specifically, the power suppression operation planning unit 110 derives the minimum operation stop time in which the demand power amount in the power suppression unit time is suppressed to be equal to or less than the threshold, and uses the derived operation stop time as the power suppression unit. Set in time.
In addition, when one unit time is extracted as the power suppression unit time, the power suppression operation planning unit 110 creates an operation scenario in which the air conditioner performs normal operation in a time within the power suppression unit time other than the operation stop time. Based on this, the operation stop time is set within the power suppression unit time so that the demand power amount in the power suppression unit time is suppressed to the threshold value or less.
In addition, when the power suppression operation planning unit 110 extracts a plurality of consecutive unit times as power suppression unit times, for example, for the last power suppression unit time, within the last power suppression unit time Based on the operation scenario in which the air conditioner performs normal operation at a time other than the operation stop time, the operation stop time is set to the end so that the demand power amount at the last power suppression unit time is suppressed below the threshold. Set within the tail power suppression unit time.
In addition, for example, for the power suppression unit time other than the last power suppression unit time, the power suppression operation planning unit 110 performs the room temperature maintenance operation at a time other than the operation stop time within the power suppression unit time. Based on the operation scenario to be performed by the machine, the operation stop time is set within the power suppression unit time so that the amount of power demand in the power suppression unit time is suppressed below the threshold.
The room temperature maintenance operation is an operation mode for maintaining the room temperature.

Furthermore, the power suppression operation planning unit 110 calculates the amount of room temperature change in the power suppression unit time due to the stop of the operation of the air conditioner.
In addition, when a plurality of power suppression unit times are extracted, the power suppression operation planning unit 110 calculates the amount of room temperature change due to the stop of the operation of the air conditioner for each power suppression unit time, and calculates the calculated power suppression unit time The sum of the room temperature changes for each is calculated as the room temperature change total.

  Next, the room temperature adjustment operation planning unit 111 will be described in more detail.

The room temperature adjustment operation planning unit 111 is one of a unit time preceding the power suppression period (first power suppression unit time) and a unit time following the power suppression period (last power suppression unit time). Then, the unit time for which the demand power amount is equal to or less than the threshold is extracted as the room temperature adjustment unit time.
Further, the room temperature adjustment operation planning unit 111 sets an offset operation time for causing the air conditioner to perform an offset operation for canceling a room temperature change in the power suppression period due to the stop of the operation of the air conditioner, in the room temperature adjustment unit time. It is set within room temperature adjustment unit time in a range where the amount of power demand is maintained below the threshold.
More specifically, the room temperature adjustment operation planning unit 111 is a range in which the amount of power demand in the room temperature adjustment unit time is maintained below the threshold and within the room temperature change amount in the power suppression period. A canceling operation time that maximizes the canceling amount is derived, and the derived canceling operation time is set within the room temperature adjustment unit time.
The room temperature adjustment operation planning unit 111 is based on an operation scenario in which the air conditioner performs the room temperature maintenance operation in a time within the room temperature adjustment unit time other than the offset operation time, and the demand electric energy in the room temperature adjustment unit time is less than the threshold value. The offset operation time is set within the room temperature adjustment unit time as long as it is maintained.
Furthermore, the room temperature adjustment operation planning unit 111 calculates the amount of offset in the room temperature adjustment unit time by the offset operation of the air conditioner.
Then, the room temperature adjustment operation planning unit 111 determines whether or not all of the room temperature change amount (room temperature change total amount) has been canceled by the offset amount, and if at least a part of the room temperature change amount has not been offset, Extract room temperature adjustment unit time.
When the unit time preceding the power suppression period is extracted as the room temperature adjustment unit time, the room temperature adjustment operation planning unit 111 extracts the unit time preceding the room temperature adjustment unit time as a new room temperature adjustment unit time.
Further, when the unit time following the power suppression period is extracted as the room temperature adjustment unit time, the room temperature adjustment operation planning unit 111 extracts the unit time following the room temperature adjustment unit time as a new room temperature adjustment unit time.
The room temperature adjustment operation planning unit 111 repeats extraction of a new room temperature adjustment unit time, setting of the offset operation time, and calculation of the amount of offset until it is determined that all of the room temperature change amount (room temperature change total amount) has been canceled.

*** Explanation of operation ***
Hereinafter, an operation example of the control device 100 according to the present embodiment will be described based on the flowchart of FIG.
In the following description, a case where peak power is suppressed by using pre-cooling during the cooling operation time will be described as an example.
Further, a case where the control target period is one day and the unit time is 30 minutes will be described as an example.
Furthermore, a case will be described as an example where there is a lower limit in the room temperature that can be lowered by precooling so that the comfort is not impaired by excessively cooling the room temperature too much.

The operation schedule generation process is automatically started in an arbitrary time zone set in advance by the user of the control device 100 or the like.
In addition, the user of the control device 100 may start the operation schedule generation process at an arbitrary timing using a keyboard or the like.

When the operation schedule generation process is started, data necessary for generating the operation schedule is first collected (step 110).
Specifically, the weather information collection unit 101 collects the temperature, humidity, and solar radiation time of the past 30 minutes.
In addition, the weather information collection unit 101 collects temperature and humidity at 30-minute intervals for the next 24 hours and weather forecast values.
The weather information collection unit 101 stores the collected information in the weather information storage unit 102.
Further, the operation result collection unit 103 collects the suction temperature, the set temperature, and the compressor frequency of the past 30 minutes of the air conditioner and stores them in the operation result storage unit 104.
In addition, the received power collection unit 105 collects the received power in the past 30 minutes and stores the collected received power in the received power storage unit 106.
Past data collected by the meteorological information collection unit 101, the operation result collection unit 103, and the received power collection unit 105 is data generated from the execution of the previous operation schedule generation process to the execution of the current operation schedule generation process.

In the present embodiment, the data to be collected is set at an interval of 30 minutes according to the unit time, but may be changed according to the length of the unit time.
Further, if the weather results, weather forecasts, air conditioner operation results, and received power can be collected at intervals smaller than unit time, these data may be collected at intervals smaller than unit time.
In the present embodiment, the data collected by the weather information collection unit 101 is temperature, humidity, and solar radiation time.
The data collected by the operation result collection unit 103 is set as the suction temperature, the set temperature, and the compressor frequency.
However, the meteorological information collection unit 101 and the operation result collection unit 103 may change the data to be collected in accordance with the data used by the thermal characteristic calculation unit 107, the thermal load calculation unit 108, and the demand power prediction unit 109.
In addition, data collection is not performed collectively at the start of the operation schedule generation process, but is automatically collected at an arbitrary time zone or time interval, and the collected data is stored in the weather information storage unit 102 and the operation result storage unit 104. The received power storage unit 106 may store the received power.

After the data collection is completed, the thermal characteristic calculation unit 107 calculates the thermal characteristic of the building (step 120).
The thermal characteristic calculation unit 107 calculates the thermal characteristic in consideration of, for example, the influence of solar radiation time or outside air temperature, the number of people in the building, the influence of heat released from terminal devices, and the like.
The thermal characteristic calculation unit 107 is a thermal circuit method using past weather record data stored in the weather information storage unit 102 and past operation record data of the air conditioner stored in the operation record storage unit 104. Thermal properties can be determined.
The thermal characteristic calculation unit 107 may obtain the thermal characteristics by a method other than the thermal network method.

After calculating the thermal characteristics, the thermal load calculation unit 108 calculates the transition (time series data) of the thermal load of the building (step 130).
The thermal load calculator 108 calculates the transition of the thermal load for the next 24 hours.
The thermal load calculation unit 108 calculates transitions (time-series data) of the thermal load necessary for maintaining various room temperatures.
For example, if the room temperature during normal operation is 27 ° C. and the room temperature is 26 ° C. during pre-cooling operation, the heat load for maintaining the room temperature at 26 ° C., the heat load for maintaining 26.1 ° C., and 26.2 ° C. The heat load for maintaining the temperature at 27 ° C. is calculated.
Note that the heat load calculation unit 108 uses the heat characteristics calculated by the heat characteristic calculation unit 107, the weather forecast data stored in the weather information storage unit 102, the predicted value of the number of people in the building, the heat released from the terminal device, etc. It is possible to calculate the transition of heat load (time series data) using the predicted value, room temperature, and the like.

Next, the demand power prediction unit 109 predicts the transition of demand power for each unit time for the next 24 hours (step 140).
The demand power prediction unit 109 uses, for example, the demand power at each time stored in the received power storage unit 106 as an objective variable, and explains the outside temperature, humidity, etc. at each time stored in the weather information storage unit 102. The power demand for each unit time can be obtained by regression analysis using variables.
Note that the power demand prediction unit 109 may obtain the power demand for each unit time using another method.

In the flowchart of FIG. 2, the demand power prediction is performed after the thermal characteristic calculation and the thermal load calculation. However, the demand power prediction may be performed before the thermal characteristic calculation and the thermal load calculation.
In the present embodiment, the transition of the heat load and power demand for the next 24 hours is predicted because the control target period is one day (the next 24 hours).
If the control target period is not a single day but a specific time zone such as morning or afternoon, the transition of the heat load and demand power only during that time zone may be predicted.

After the thermal load is calculated by the thermal load calculation unit 108 and the demand power is predicted by the demand power prediction unit 109, the power suppression operation planning unit 110 plans an operation schedule for the power suppression period (step 150).
Details of the operation schedule plan for the power suppression period (step 150) will be described based on the flowcharts of FIGS.

In the operation schedule plan for the power suppression period, first, the power suppression operation planning unit 110 sets the _normal room temperature T _normal and the lower limit value T _min of the room temperature allowable range (step 151).
The normal room temperature T _normal is a room temperature when the air conditioner is not controlled for power suppression, and is arbitrarily set by the user.
The lower limit value T _min of the room temperature allowable range is a lower limit value of the room temperature allowable by the user and is arbitrarily set by the user.
The operation schedule of the power suppression period planned by the power suppression operation planning unit 110 can most suppress peak power (demand power for each unit time during the power suppression period) while maintaining the room temperature within the room temperature allowable range set by the user. It is what you want to do.

Next, the power suppression operation planning unit 110 sets the highest demand power among the predicted power demand values of each unit time for the next 24 hours calculated by the demand power prediction unit 109 as the peak power P _max after power suppression. (Step 152).
And the electric power suppression operation plan part 110 sets the demand electric power which subtracted arbitrary constant (epsilon) from the peak electric power _Pmax after electric power suppression as _Ptemp (step 153).

After setting the P _temp, the power suppression operation plan unit _{110, P temp} and compares the electric power demand prediction value of each unit time of the next 24 _hours, all power suppress high unit time electric power demand prediction value than _{P temp} The period is set (step 154).
That is, the power suppression operation planning unit 110 extracts a power suppression unit time that is a unit time that is a target of power suppression.

After setting the power suppression period, the power suppression operation planning unit 110 plans an operation schedule for the power suppression period.
First, the power suppression operation planning unit 110 plans an operation schedule for the a (= 1) th unit time (hereinafter, unit time a) from the end of the power suppression period (step 155).
Next, the power suppression operation planning unit 110 sets the operation stop time x of the unit time a to 1 minute (x = 1) (step 156).
Then, the power suppression operation planning unit 110 stops the air conditioner for x minutes in the unit time a, and calculates the demand power Pa _{, x} when the normal operation is performed for (30-x) minutes (step 157).
The demand power Pa _{, x} is obtained from the transition of the thermal load per unit time a calculated by the thermal load calculation unit 108 and the demand power predicted value per unit time a calculated by the demand power prediction unit 109.
First, the power suppression operation planning unit 110 calculates the thermal load b that was scheduled to be supplied during the operation stop time of x minutes based on the transition of the thermal load when the normal operation is performed in the unit time a.
FIG. 5 shows a method for calculating the thermal load b.
The thermal load b scheduled to be supplied can be calculated by time-integrating the time series data of the thermal load of the unit time a calculated by the thermal load calculation unit 108.
Next, the power suppression operation planning unit 110 converts the thermal load b into electric power, and calculates demand power that can be reduced by stopping the air conditioner for x minutes.
Then, if the demand power that can be reduced by stopping the air conditioner is subtracted from the demand power predicted value of the unit time a calculated by the demand power prediction unit 109, the air conditioner is stopped for x minutes in the unit time a, and (30−x ) Demand power Pa _{, x} in the case of normal operation for a minute can be calculated.

After calculating the demand power Pa _{, x} , the power suppression operation planning unit 110 compares _{Pa , x} with _Ptemp (step 158).
If the demand power _{Pa , x} is larger than _Ptemp , the power suppression operation planning unit 110 increases the operation stop time x of the unit time a by 1 minute (x = x + 1) (step 159).
Then, returning to step 157, the power suppression operation planning unit 110 again stops the air conditioner for x minutes _, and calculates the demand power Pa _{, x} when the normal operation is performed for (30-x) minutes.
If the demand power _{Pa , x} is smaller than P _temp , the power suppression operation planning unit 110 sets the start x minutes of the unit time a as the operation stop time of the air conditioner as the operation schedule of the unit time a. Thereafter, the normal operation time is set for (30-x) minutes (step 160).

After planning the operation schedule for the unit time a, the power suppression operation planning unit 110 calculates _a change amount _{Ta, x} of the room temperature that increases due to the air conditioner being stopped for x minutes in the unit time a (step). 161).
The power suppression operation planning unit 110 can obtain the room temperature change amount _{Ta, x} by the following formula 1 based on the thermal load b calculated in step 157 and the heat capacity of the thermal characteristics calculated by the thermal characteristic calculation unit 107.
Change in room temperature = heat load / heat capacity (Equation 1)

After calculating the room temperature change amount Ta _{, x} , the power suppression operation planning unit 110 confirms whether the operation schedule is planned for all unit times set as the power suppression period in step 154 (step 162).
If the operation schedule has not been planned for all unit times, the operation schedule for the a (≧ 2) th unit time from the end of the power suppression period is planned with a = a + 1 (step 163). .

In the operation schedule plan for the unit time a (≧ 2), as in step 156, the power suppression operation plan unit 110 first sets the operation stop time x to 1 minute (x = 1) (step 164).
Next, the power suppression operation planning unit 110 stops the air conditioner for x minutes in the unit time a (≧ 2), and calculates the demand power Pa _{, x} when the room temperature maintenance operation is performed for (30−x) minutes ( Step 165).
The room temperature maintenance operation is an operation for maintaining the effect of precooling or preheating in advance (cooled room temperature or warmed room temperature).
The room temperature maintaining operation in the case of utilizing pre-cooling is an operation in which the set temperature is lowered in order to maintain a room temperature lower than the normal time T _normal , so that the power demand increases compared to the case of normal operation.

The demand electric power Pa _{, x} when the air conditioner is stopped for x minutes at the unit time a (≧ 2) and the room temperature is maintained for (30−x) minutes is the heat of the unit time a calculated by the thermal load calculation unit 108. It is obtained from the transition of load and the predicted power demand per unit time a calculated by the power demand prediction unit 109.
First, the power suppression operation planning unit 110 calculates the thermal load b that was to be supplied during the operation stop time of x minutes based on the transition of the thermal load during normal operation of unit time a.
The thermal load b scheduled to be supplied can be calculated by time-integrating the time series data of the thermal load of the unit time a (≧ 2) calculated by the thermal load calculation unit 108 as in step 157.
Next, the power suppression operation planning unit 110 determines the thermal load c supplied in excess of the normal operation by the room temperature maintenance operation based on the transition of the thermal load during the room temperature maintenance operation and the transition of the heat load during the normal operation. calculate.
As shown in FIG. 6, the thermal load c is calculated by taking the difference between the time-integrated time-series data of the heat load during the room temperature maintenance operation and the time-integrated time-series data of the heat load during the normal operation. Can do.
In the room temperature maintenance operation, the necessary heat load varies depending on the room temperature to be maintained.
The room temperature that must be maintained in the unit time a (≧ 2) can be obtained from the normal room temperature T _normal and the room temperature change amount _{Ta, x} for each unit time for which the operation schedule has been planned so far.
For example, when the operation schedule of unit time a = 3 is planned, the room temperature that must be maintained during the room temperature maintenance operation of unit time a = 3 is the unit time a = 1 and the unit time a = from the _normal room temperature T _normal. 2 is the room temperature obtained by subtracting the total room temperature change value (T _{1, x} + T _{2, x} ).
The transition of the heat load for maintaining each room temperature is calculated by the heat load calculation unit 108.

After calculating the thermal load b and the thermal load c, the power suppression operation planning unit 110 converts each of the thermal load b and the thermal load c into electric power.
The heat load b is a demand power that can be reduced by stopping the air conditioner for x minutes, and the heat load c is a demand power that is increased by operating at room temperature for (30-x) minutes.
Then, the power suppression operation planning unit 110 subtracts the demand power that can be reduced by stopping the air conditioner for x minutes from the demand power predicted value of the unit time a calculated by the demand power prediction unit 109.
Further, the power suppression operation planning unit 110 stops the air conditioner for x minutes in the unit time a (≧ 2) by adding the demand power that is increased by maintaining the room temperature for (30−x) minutes to the subtraction value. Then, it is possible to calculate the demand power Pa _{, x} when the room temperature maintenance operation is performed for (30-x) minutes.

After calculating the demand power Pa _{, x} when the air conditioner is stopped for x minutes in the unit time a (≧ 2) and maintained at room temperature for (30−x) minutes, the power suppression operation planning unit 110 _{a and x} are compared with P _temp (step 166).
If the demand power _{Pa , x} is larger than _Ptemp , the power suppression operation planning unit 110 increases the operation stop time x of the unit time a by 1 minute (x = x + 1) (step 167).
Then, returning to step 165, the power suppression operation planning unit 110 again calculates the demand power Pa _{, x} when the air conditioner is stopped again for x minutes and the room temperature maintenance operation is performed for (30−x) minutes.

If the demand power _{Pa , x} is smaller than _Ptemp , the power suppression operation planning unit 110 uses the start x minutes of the unit time a as the operation schedule of the unit time a (≧ 2) of the air conditioner. The operation stop time is set, and then (30-x) minutes are set as the room temperature maintenance operation time (step 168).
The operation schedule of unit time a (≧ 2) is to suppress the power by using the effect of pre-cooling by stopping the air conditioner for x minutes, and to use the effect of pre-cooling in other unit times, The room temperature will be maintained for (30-x) minutes.

After planning the operation schedule for unit time a, similarly to step 161, the power suppression operation planning unit 110 increases the room temperature change amount T _{a, x} that is increased by stopping the air conditioner for x minutes in unit time a. Is calculated by Equation 1 (step 169).

After calculating the room temperature change amount Ta , x , the process returns to step 162, and in step 154, the power suppression operation planning unit 110 confirms whether the operation schedule is planned for all unit times set as the power suppression period.
If the operation schedule in all the unit time is planned, the power suppression operation plan unit 110, room temperature variation of the sum "Σ a n = 1 T n to rise by the stop of the air conditioner of the power suppression period , X "(step 170).
Then, if is within between the total value of the room temperature variation, "Σ a n = 1 T n, x " is from normal room temperature T normal lower limit T min at room temperature tolerance, the unit of power suppression period It means that the operation stop time of time (each power suppression time) is lengthened and further peak power suppression is possible.
For this reason, the power suppression operation planning unit 110 plans again an operation schedule in which the peak power P max after power suppression is further suppressed.
Specifically, the power suppression operation plan unit 110 sets the P temp as peak power P max after power restriction (step 172), "T normal -Σ a n to room temperature T goal should be lowered until power suppression period = 1 T n, x ”is set (step 173).
Then, returning to step 153, the power suppression operation planning unit 110 plans an operation schedule for the power suppression period when the peak power is further suppressed.

If the total value Σ ^a _{n = 1} T _{n, x} of the room temperature change amount that increases due to the stop of the air conditioner during the power suppression period in step 171 does not _fall between the lower limit value T _min and the normal value T _normal of the room temperature. If so, the peak power cannot be suppressed to P _temp while maintaining the allowable range of room temperature.
Therefore, P _max set in step 152 or step 172 is the peak power that can be suppressed most while maintaining the room temperature allowable range.
Then, the power suppression period set in step 154 when the peak power is P _max and the operation schedule of each unit time planned in step 160 and step 168 become the operation schedule of the power suppression period, and the power suppression operation planning process is completed. .

FIG. 7 shows the operation schedule during the power suppression period and the transition of the room temperature.
FIG. 8 shows the operation schedule during the power suppression period and the transition of demand power for each unit time.
In the operation schedule planned by the power suppression operation planning unit 110 in the power suppression operation plan processing (step 150), the room temperature changes within the allowable range (between the lower limit value _Tmin and the normal value _Tnormal ) as shown in FIG. In addition, as shown in FIG. 8, the demand power for each unit time in the power suppression period is equal to or less than the peak power _Pmax .

After the power suppression operation plan is completed, as shown in FIG. 3, the room temperature adjustment operation plan unit 111 creates an operation schedule for the precooling / preheating period (step 180).
The flow of the operation schedule plan in the precooling / preheating period will be described based on the flowcharts of FIGS.

In the operation schedule plan for the room temperature adjustment period, the room temperature adjustment operation planning unit 111 first sets a _normal room temperature T _normal (step 181).
T _normal is the same as that set in the power suppression operation plan.
In addition, the room temperature adjustment operation planning unit 111 sets the room temperature T _{goal, 1} that must be reduced by the power suppression period (first power suppression unit time) (step 182).
T _{goal, 1} sets the value T _goal calculated in step 173 of the power suppression operation plan.
Next, the room temperature adjustment operation planning unit 111 sets the peak power P _max when the power is suppressed (step 183).
P _max is set to the value calculated in step 172 of the power suppression operation plan.
After the setting of T _normal , T _{goal, 1} and P _max is completed, the room temperature adjustment operation planning unit 111 plans an operation schedule for the precooling / preheating period.

First, the room temperature adjustment operation planning unit 111 plans an operation schedule for d (= 1) previous unit times (hereinafter, unit time d) of the power suppression period (step 184).
That is, the room temperature adjustment operation planning unit 111 extracts a unit time d (= 1) before the first power suppression unit time as the room temperature adjustment unit time.

Next, the room temperature adjustment operation planning unit 111 sets the precooling time x of the unit time d to 1 minute (x = 1) (step 185).
In addition, the room temperature adjustment operation planning unit 111 calculates a room temperature change amount T _{d, x} that can be lowered by pre-cooling for x minutes in the unit time d (step 186).
The room temperature adjustment operation planning unit 111 calculates T _{d, x} based on the transition of the thermal load of the unit time d calculated by the thermal load calculation unit 108.
Specifically, the room temperature adjustment operation planning unit 111 calculates T _{d, x} based on the heat load e supplied in excess of the normal operation during the x-minute precooling operation of the unit time d.

FIG. 11 shows a method for calculating the thermal load e.
The thermal load e can be calculated by taking the difference between the time-integrated time-series data of the heat load during the pre-cooling operation and the time-integrated time-series data of the heat load during the normal operation.

If the thermal load e can be calculated, the room temperature change amount T _{d, x} that can be lowered by the pre-cooling for x minutes in the unit time d can be calculated according to Equation 1.
After calculating the room temperature change amount T _{d, x} , the room temperature adjustment operation planning unit 111, in the unit time d, demand power P _d, when (30-x) minutes are maintained at room temperature and x minutes are pre-cooled _{. x} is calculated (step 187).
The demand power P _{d, x} is obtained from the transition of the thermal load per unit time d calculated by the thermal load calculation unit 108 and the demand power predicted value per unit time d calculated by the demand power prediction unit 109.
In the calculation of the demand power P _{d, x} , the room temperature adjustment operation planning unit 111 first normally performs the x-minute pre-cooling operation of the unit time d based on the transition of the thermal load of the unit time d calculated by the thermal load calculation unit 108. The heat load e supplied more excessively than the operation and the heat load f supplied more excessively than the normal operation are obtained by the room temperature maintenance operation for (30−x) minutes.
As the thermal load e, the one obtained in step 186 is used.
As shown in FIG. 12, the heat load f is calculated by taking the difference between the time-integrated time-series data of the heat load during the room temperature maintaining operation and the time-integrated time-series data of the heat load during the normal operation. Can do.
As described above, in the room temperature maintenance operation, the required heat load changes depending on the room temperature to be maintained.
The room temperature that must be maintained for the unit time d is the room temperature T _{goal, d} plus the room temperature change T _{d, x} .
If the room temperature to be maintained is known, the room temperature adjustment operation planning unit 111 selects the transition of the thermal load during the room temperature maintenance operation from the transition of the thermal load for maintaining each room temperature calculated by the thermal load calculation unit 108. be able to.
After the calculation of the thermal load e and the thermal load f, the room temperature adjustment operation planning unit 111 converts each of the thermal load e and the thermal load f into electric power, and (30−x) ) Calculate power demand that increases due to room temperature maintenance operation for a minute.
Then, if the demand power increased by the pre-cooling operation for x minutes and the demand power increased by the room temperature maintenance operation for (30-x) minutes are added to the demand power predicted value of the unit time d calculated by the demand power prediction unit 109, the unit It is possible to calculate the demand power P _{d, x} when the room temperature maintaining operation is performed for (30−x) minutes and the precooling operation is performed for x minutes at time _d .

After calculating the demand power P _{d, x} , the room temperature adjustment operation planning unit 111 compares P _{d, x} with the peak power P _max after power suppression (step 188).
If P _{d, x} is smaller than P _max , the precooling time can be further increased in the unit time d.
When P _{d, x} is smaller than P _max , the room temperature adjustment operation planning unit 111 checks the _normal room temperature T _normal to the room temperature T _{goal, d} by pre-cooling for x minutes in order to confirm whether the pre-cooling time should be increased by the unit time _d. Whether the temperature is lowered to room temperature is confirmed by the room temperature change amount T _{d, x} (step 189).
If the room temperature change T _{d, x} due to pre-cooling for x minutes is smaller than the change from T _normal to T _{goal, d} , the pre-cooling time must be lengthened.
In this case, the room temperature adjustment operation planning unit 111 increases the precooling time of the unit time d by 1 minute (x = x + 1) (step 190).
Then, the room temperature adjustment operation planning unit 111 returns to Step 187 and calculates the demand power P _{d, x} again.
If, _{P d,} if the _x is greater than _{P max,} exceeds the peak power _{P max} when precooling x minutes in the unit time d in comparison to _{P d, x} and power suppression after the peak power _{P max} in step 188 It will end up.
For this reason, the pre-cooling time must be (x-1) minutes in unit time d.
Therefore, in unit time d, first, a room temperature maintaining operation for (30−x + 1) minutes is performed, and an operation schedule for performing a precooling operation for (x−1) minutes (step 191).

After the operation schedule planning for the unit time d, the room temperature adjustment operation planning unit 111 starts the operation schedule planning with the previous unit time (d (= d + 1) times before the power suppression period) as the pre-cooling period (step 192). ).
For this purpose, first, room temperature T _{goal, d} that must be lowered by unit time _d is calculated (step 193).
T _{goal, d} is the change in room temperature T _{d-1, x-1} reduced in unit time (d-1) to T _{goal, d-1} , which had to be reduced in unit time (d-1). It can be calculated by adding together.
After the room temperature T _{goal, d} that must be lowered by the unit time d is determined, the room temperature adjustment operation planning unit 111 returns to step 185, does not exceed the peak power P _max , and the precooling time x minutes is the longest. Such an operation schedule for unit time d is obtained in steps 186 to 190.

If the room temperature change amount T _{d, x} due to pre-cooling for x minutes of unit time d in step 189 is larger than the change from T _normal to T _{goal, d} , the target room temperature T _{goal, d is obtained} by pre-cooling for x minutes. It has been lowered to.
For this reason, the room temperature adjustment operation planning unit 111 first performs the normal operation for (30-1) minutes in the unit time d, and sets the operation schedule to perform the pre-cooling operation for x minutes (step 194).
An operation schedule for the room temperature adjustment period can be planned through steps 180 to 194.
As shown in FIG. 13, the planned operation schedule gradually decreases the room temperature by dividing it into a plurality of unit times before the start of the power suppression period.
Further, in the planned operation schedule, the precooling time x is adjusted so that the demand power of each unit time in the room temperature adjustment period does not exceed the peak power _Pmax as shown in FIG.

When the power suppression operation plan and the room temperature adjustment operation plan are completed, the operation schedule generation unit 112 generates a daily operation schedule based on the operation schedules of the power suppression period and the room temperature adjustment period (step 200).
In addition, each unit time other than the power suppression period and the room temperature adjustment period is performed as shown in FIG.

In the above, the case where pre-cooling is used in the cooling operation timing has been described as an example. However, as shown in FIGS. 16 and 17, the peak power is suppressed by using the follow-up cooling (also referred to as post-cooling) in the cooling operation timing. It is also possible to do.
Follow-up cooling is to stop the air conditioner during the power suppression period and follow-up cooling (intensify the cooling) in each unit time of the follow-up cooling period after the power suppression period. This is a peak shift technique that gradually lowers to normal room temperature _Tnormal .
Similarly, the air conditioner is stopped during the power suppression period by follow-up heating (also referred to as post-heating), and the follow-up heating is performed in each unit time of the follow-up heating period after the power suppression period (increasing heating). It is also possible to gradually increase the room temperature lowered by stopping the conditioner and return it to the _normal room temperature _Tnormal .

FIG. 18 is a workflow diagram in the case where peak power is suppressed by using follow-up cooling / follow-up heating.
The process of planning the operation schedule for the power suppression period (step 210) and the process of planning the operation schedule for the follow-up cooling / follow-up heating period (step 240) are different from the case of using the pre-cooling / pre-heating in FIG.
In the following description, a case will be described as an example where the peak power is suppressed by utilizing the follow-up cooling during the cooling operation timing.

  The flow of the operation schedule plan during the power suppression period when using the follow-up cooling is as shown in the flowcharts of FIGS. 19 and 20.

In the planning of the operation schedule during the power suppression period when the follow-up cooling is utilized, first, the power suppression operation planning unit 110 sets the _normal room temperature T _normal and the upper limit value T _max of the room temperature allowable range (step 211).
The upper limit value _Tmax of the room temperature allowable range is an upper limit value of the room temperature allowable by the user, and is arbitrarily set by the user.
Next, the power suppression operation planning unit 110 sets the highest demand power among the demand power predicted values for each unit time for the next 24 hours calculated by the demand power prediction unit 109 as the peak power P _max after power suppression. (Step 212).
And the electric power suppression operation plan part 110 sets the demand electric power which subtracted arbitrary constant (epsilon) from the peak electric power _Pmax after electric power suppression as _Ptemp (step 213).

After setting the P _temp, the power suppression operation plan unit _{110, P temp} and compares the electric power demand prediction value of each unit time of the next 24 _hours, all power suppress high unit time electric power demand prediction value than _{P temp} The period is set (step 214).
That is, the power suppression operation planning unit 110 extracts a power suppression unit time that is a unit time that is a target of power suppression.

After setting the power suppression period, the power suppression operation planning unit 110 plans an operation schedule for the power suppression period.
First, the power suppression operation planning unit 110 plans an operation schedule for the g (= 1) th unit time (hereinafter, unit time g) from the beginning of the power suppression period (step 215).
Next, the power suppression operation planning unit 110 sets the operation stop time x of the unit time g to 1 minute (x = 1) (step 216).
Then, the power suppression operation planning unit 110 calculates the demand power P _{g, x} when the air conditioner is stopped for x minutes in the unit time g and is normally operated for (30−x) minutes (step 217).
The demand power P _{g, x} is obtained from the transition of the thermal load per unit time g calculated by the thermal load calculation unit 108 and the demand power predicted value per unit time g calculated by the demand power prediction unit 109.
First, the power suppression operation planning unit 110 calculates the thermal load h that was scheduled to be supplied during the operation stop time of x minutes based on the transition of the thermal load when the normal operation is performed in the unit time g.
FIG. 21 shows a method for calculating the thermal load h.
The thermal load h that was scheduled to be supplied can be calculated by time-integrating the time-series data of the thermal load of the unit time g calculated by the thermal load calculation unit 108.
Next, the power suppression operation planning unit 110 converts the heat load h into electric power, and calculates demand power that can be reduced by stopping the air conditioner for x minutes.
Then, if the demand power that can be reduced by stopping the air conditioner is subtracted from the demand power predicted value of the unit time g calculated by the demand power prediction unit 109, the air conditioner is stopped for x minutes in the unit time g, and (30−x ) Demand power _{Pg, x} in the case of normal operation for a minute can be calculated.

After calculating the demand power _{Pg, x} , the power suppression operation planning unit 110 compares _{Pg , x} with _Ptemp (step 218).
If the demand power P _{g, x} is larger than P _temp , the power suppression operation planning unit 110 increases the operation stop time x of the unit time g by 1 minute (x = x + 1) (step 219).
Then, returning to Step 217, the power suppression operation planning unit 110 calculates the demand power _{Pg, x} when the normal operation is again performed for (30-x) again and the air conditioner is stopped for x minutes.
If the demand power P _{g, x} is smaller than P _temp , the power suppression operation planning unit 110 sets the operation schedule for the unit time g as the normal operation time for the start (30−x) minutes of the unit time g. Then, x minutes are set as the operation stop time of the air conditioner (step 220).

After planning the operation schedule for the unit time g, the power suppression operation planning unit 110 calculates the change amount T _{g, x} of the room temperature that rises when the air conditioner is stopped for x minutes in the unit time g (step) 221).
The power suppression operation planning unit 110 can obtain the room temperature change amount T _{g, x} by using the thermal load h calculated in Step 217 and the heat capacity of the thermal characteristics calculated by the thermal characteristic calculation unit 107 according to Equation 1.

After calculating the room temperature change amount _{Tg, x} , the power suppression operation planning unit 110 confirms whether the operation schedule is planned for all unit times set as the power suppression period in step 214 (step 222).
If the operation schedule has not been planned for all unit times, the operation schedule for the g (≧ 2) th unit time from the beginning of the power suppression period is planned with g = g + 1 (step 223). .

In the operation schedule plan with the unit time g (≧ 2), the operation stop time x is first set to 1 minute (x = 1) as in step 216 (step 224).
Next, the power suppression operation planning unit 110 calculates the demand power P _{g, x} when the room temperature is maintained for (30−x) minutes in the unit time g (≧ 2) and the air conditioner is stopped for x minutes ( Step 225).
The room temperature maintaining operation in the case of utilizing the follow-up cooling is an operation in which the set temperature is increased in order to maintain a room temperature higher than the normal time T _normal, and thus the power demand is reduced as compared with the case of the normal operation.

Demand electric power P _{g, x} when operating at room temperature for (30−x) minutes at unit time g (≧ 2) and stopping the air conditioner for x minutes is the heat of unit time g calculated by the thermal load calculation unit 108. It is obtained from the transition of the load and the demand power predicted value per unit time g calculated by the demand power prediction unit 109.
First, the power suppression operation planning unit 110 calculates the thermal load h that was scheduled to be supplied during the operation stop time of x minutes based on the transition of the thermal load during normal operation of unit time g.
The thermal load h that was scheduled to be supplied can be calculated by time-integrating the time series data of the thermal load of the unit time g (≧ 2) calculated by the thermal load calculation unit 108 as in step 217.
Next, the power suppression operation planning unit 110 calculates the thermal load i that is smaller than that in the normal operation due to the room temperature maintenance operation based on the change in the thermal load during the room temperature maintenance operation and the change in the heat load during the normal operation. .
As shown in FIG. 22, the heat load i is calculated by taking the difference between the time-integrated time-series data of the heat load during normal operation and the time-integrated time-series data of the heat load during the room temperature maintaining operation. Can do.
In the room temperature maintenance operation, the necessary heat load varies depending on the room temperature to be maintained.
The room temperature that must be maintained at the unit time g (≧ 2) can be obtained from the normal room temperature T _normal and the room temperature change amount _{Ta, x} for each unit time for which the operation schedule has been planned so far.
For example, when an operation schedule of unit time g = 3 is planned, the room temperature that must be maintained during the room temperature maintenance operation of unit time g = 3 is the normal room temperature T _normal , unit time g = 1 and unit time g = The total room temperature change value (T _{1, x} + T _{2, x} ) of ₂ is added to the room temperature.
The transition of the heat load for maintaining each room temperature is calculated by the heat load calculation unit 108.

After calculating the thermal load h and the thermal load i, the power suppression operation planning unit 110 converts each of the thermal load h and the thermal load i into electric power.
The heat load h is demand power that can be reduced by stopping the air conditioner for x minutes, and the heat load i is demand power that can be reduced by operating at (30-x) minutes at room temperature.
Then, the power suppression operation planning unit 110 maintains the room temperature of the demand power that can be reduced by stopping the air conditioner for x minutes from the demand power predicted value of the unit time g calculated by the demand power prediction unit 109 and (30−x) minutes at room temperature. If the demand power that can be reduced by operation is subtracted, the demand power P _{g, x} is calculated when the room temperature is maintained for (30−x) minutes and the air conditioner is stopped for x minutes in the unit time g (≧ 2). Can do.

After calculating the demand electric power _{Pg, x} when the unit time g (≧ 2) is maintained at room temperature for (30−x) minutes and the air conditioner is stopped for x minutes, the power suppression operation planning unit 110 _{g and x} are compared with P _temp (step 226).
If the demand power P _{g, x} is larger than P _temp , the power suppression operation planning unit 110 increases the operation stop time x of the unit time g by 1 minute (x = x + 1) (step 227).
Then, returning to step 225, the power suppression operation planning unit 110 calculates the demand power _{Pg, x} when the room temperature maintenance operation is performed again for (30-x) minutes and the air conditioner is stopped for x minutes.

If the demand power P _{g, x} is smaller than P _temp , set the start (30-x) minutes of the unit time g as the room temperature maintenance operation time as the operation schedule of the unit time g (≧ 2), Thereafter, x minutes are set as the operation stop time of the air conditioner (step 228).
The operation schedule of unit time g (≧ 2) is based on the unit time g (≧ 2) while keeping the room temperature increased by the stop of the air conditioner executed in the unit time so far during the power suppression period for (30−x) minutes. ) To stop the air conditioner for x minutes.
In this operation schedule, the power consumption is not increased because the operation for lowering the room temperature is not performed.
Moreover, demand power can be suppressed by raising room temperature within the range of room temperature permitted by the user.
After planning the operation schedule for unit time g, similarly to step 221, the power suppression operation planning unit 110 increases the room temperature change amount T _{g, x} that is increased by stopping the air conditioner for x minutes in unit time g. Is calculated by Equation 1 (step 229).

After calculating the room temperature change amount _{Tg, x} , the process returns to step 222, and in step 214, the power suppression operation planning unit 110 confirms whether the operation schedule is planned for all unit times set as the power suppression period.
If the operation schedule is planned for all the unit times, the power suppression operation planning unit 110 determines that the total room temperature change amount “Σ ^g _{n = 1} T _{n that} increases due to the stop of the air conditioner during the power suppression period”. _{, X} "(step 230).
If the total value “Σ ^gn _{= 1} T _{n, x} ” of the room temperature change amount is within the upper limit value T _max of the room temperature allowable range from the _normal room temperature T _normal , each unit of the power suppression period It means that the operation stop time of time (each power suppression time) is lengthened and further peak power suppression is possible.
For this reason, the power suppression operation planning unit 110 plans again an operation schedule in which the peak power P _max after power suppression is further suppressed.
Specifically, the power suppression operation planning unit 110 sets P _temp as the peak power P _max after power suppression (step 232), and sets “T” to the room temperature T _start that rises due to the stop of the air conditioner during the power suppression period. ^{_{normal + Σ g n = 1 T}} n, setting the _x "(step 233).
Then, returning to step 213, the power suppression operation planning unit 110 plans an operation schedule for the power suppression period when the peak power is further suppressed.

If the total value Σ ^g _{n = 1} T _{n, x} of the room temperature change that increases due to the air conditioner being stopped during the power suppression period in step 231 does not _fall between the upper limit value T _max and the normal value T _normal of the room temperature. If so, the peak power cannot be suppressed to P _temp while maintaining the allowable range of room temperature.
Therefore, P _max set in step 212 or step 232 is the peak power that can be suppressed most while maintaining the room temperature allowable range.
Then, when the peak power is P _max , the power suppression period set in step 214 and the operation schedule of each unit time planned in steps 220 and 228 become the operation schedule of the power suppression period, and the power suppression operation at the time of using the subsequent cooling The planning process is complete.

FIG. 23 shows the operation schedule and the transition of the room temperature during the power suppression period when the follow-up cooling is utilized.
FIG. 24 shows the transition of the operation schedule during the power suppression period when using the follow-up cooling and the demand power for each unit time.
As shown in FIG. 23, the operation schedule planned by the power suppression operation planning unit 110 in the power suppression period planning process (step 210) at the time of using the follow-up cooling is that the room temperature is within an allowable range (upper limit value T _max and normal value T _normal ). In addition, as shown in FIG. 24, the demand power for each unit time of the power suppression period is equal to or less than the peak power _Pmax .

After the power suppression operation plan is completed, an operation schedule for the follow-up cooling / follow-up heating period is created (step 240).
The operation schedule plan for the follow-up cooling / follow-up heating period will be described with reference to the flowcharts of FIGS.

In the operation schedule plan for the follow-up cooling / follow-up heating period, the room temperature adjustment operation planning unit 111 first sets the _normal room temperature T _normal (step 241).
T _normal is the same as that set in the power suppression operation plan.
In addition, the room temperature adjustment operation planning unit 111 sets the room temperature T _{start, 1} that has increased due to the stop of the air conditioner during the power suppression period (step 242).
T _{start, 1} sets the value T _start calculated in step 233 of the power suppression operation plan.
Next, the room temperature adjustment operation planning unit 111 sets the peak power P _max when the power is suppressed (step 243).
P _max is set to the value calculated in step 212 or step 232 of the power suppression operation plan.
After the setting of T _normal , T _{start, 1} and P _max is completed, the room temperature adjustment operation planning unit 111 plans an operation schedule for the follow-up cooling / follow-up heating period.
First, an operation schedule for a unit time (hereinafter, unit time j) j (= 1) times after the power suppression period is planned (step 244).
That is, the room temperature adjustment operation planning unit 111 extracts the unit time after j (= 1) times of the last power suppression unit time as the room temperature adjustment unit time.

Next, the follow-up cooling time x for the unit time j is set to 1 minute (x = 1) (step 245).
Then, the room temperature adjustment operation planning unit 111 calculates a room temperature change amount T _{j, x} that can be lowered by follow-up cooling for x minutes in the unit time j (step 246).
The room temperature adjustment operation planning unit 111 calculates T _{j, x based} on the thermal load transition of the unit time j calculated by the thermal load calculation unit 108.
Specifically, the room temperature adjustment operation planning unit 111 calculates T _{j, x} based on the thermal load k supplied in excess of the normal operation during the follow-up cooling operation for x minutes of the unit time j.

FIG. 27 shows a method for calculating the thermal load k.
The heat load k can be calculated by taking the difference between the time-integrated time series data of the heat load during the follow-up cooling operation and the time-integrated time series data of the heat load during the normal operation.

If the thermal load k can be calculated, the room temperature change amount T _{j, x} that can be reduced by follow-up cooling for x minutes in the unit time j can be calculated by Equation 1.
After calculating the room temperature change amount T _{j, x} , the room temperature adjustment operation planning unit 111 performs the demand power P _j when the unit time j is the follow-up cooling operation for x minutes and the room temperature maintenance operation for (30−x) minutes. _{, X} are calculated (step 247).
The demand power P _{j, x} is obtained from the transition of the thermal load per unit time j calculated by the thermal load calculation unit 108 and the demand power predicted value per unit time j calculated by the demand power prediction unit 109.
In calculating the demand power P _{j, x} , the room temperature adjustment operation planning unit 111 first performs the follow-up cooling operation for x minutes of the unit time j based on the transition of the thermal load of the unit time j calculated by the thermal load calculation unit 108. The heat load k supplied in excess of the normal operation and the heat load 1 reduced from the normal operation by the room temperature maintaining operation for (30−x) minutes are obtained.
As the thermal load k, the one obtained in step 246 is used.
As shown in FIG. 28, the thermal load l is calculated by taking the difference between the time-integrated time series data of the thermal load during normal operation and the time-integrated time series data of the thermal load during the room temperature maintenance operation. Can do.
As described above, in the room temperature maintenance operation, the required heat load changes depending on the room temperature to be maintained.
The room temperature that must be maintained in unit time j is the room temperature T _{start, j} minus the room temperature change T _{j, x} .
If the room temperature to be maintained is known, the room temperature adjustment operation planning unit 111 selects the transition of the thermal load during the room temperature maintenance operation from the transition of the thermal load for maintaining each room temperature calculated by the thermal load calculation unit 108. be able to.
After the calculation of the thermal load k and the thermal load l, the room temperature adjustment operation planning unit 111 converts each of the thermal load k and the thermal load l into electric power, and (30− x) The power demand that decreases due to the room temperature maintenance operation for a minute is calculated.
Then, the demand power increased by the follow-up cooling operation for x minutes is added to the demand power prediction value of the unit time j calculated by the demand power prediction unit 109, and the demand power decreased by the room temperature maintenance operation for (30−x) minutes is subtracted. For example, in the unit time j, it is possible to calculate the demand power P _{j, x} when the follow-up cooling operation is performed for x minutes and the room temperature maintenance operation is performed for (30−x) minutes.

After calculating the demand power P _{j, x} , the room temperature adjustment operation planning unit 111 compares P _{j, x} with the peak power P _max after power suppression (step 248).
If P _{j, x} is smaller than P _max , the follow-up cooling time can be further increased in unit time j.
When P _{j, x} is smaller than P _max , the room temperature adjustment operation planning unit 111 stops the air conditioner during the power suppression period by follow-up cooling for x minutes in order to confirm whether the follow-up cooling time should be increased by unit time j. Whether the temperature is lowered from the room temperature T _{start, j} raised by the above to the _normal room temperature T _normal is confirmed by the room temperature change amount T _{j, x} (step 249).
If the room temperature change amount T _{j, x} due to follow-up cooling for x minutes is smaller than the change of T _normal from T _{start, j} , the follow-up cooling time must be lengthened.
In this case, the room temperature adjustment operation planning unit 111 increases the precooling time of the unit time j by 1 minute (x = x + 1) (step 250).
Then, the room temperature adjustment operation planning unit 111 returns to step 247 to calculate the demand power P _{j, x} again.
If, _{P j,} if the _x is greater than _{P max,} exceeds the peak power _{P max} when chasing cooling after x minutes in the unit time j by comparing _{P j, x} and peak after power suppression power _{P max} in step 248 It will end up.
For this reason, in the unit time j, the follow-up cooling time must be (x-1) minutes.
Therefore, in the unit time j, first, the follow-up cooling operation is performed for (x-1) minutes, and the operation schedule for performing the room temperature maintenance operation for (30-x + 1) minutes is obtained (step 251).

After the operation schedule planning for the unit time j, the room temperature adjustment operation planning unit 111 starts the operation schedule planning with the unit time further later (j (= j + 1) times before the power suppression period) as the follow-up cooling period (step) 252).
For this purpose, first, a room temperature T _{start, j} that rises by stopping the operation of the air conditioner during the power suppression period and approaches the _normal room temperature T _normal by the follow-up cooling up to the unit time (j−1) is calculated. (Step 253).
T _{start, j} is a room temperature change amount T _j that is lowered by unit time (j−1) from room temperature T _{start, j−1 that is} brought close to _normal room temperature T _normal by follow-up cooling to unit time (j−1). _It can be calculated by subtracting _{−1 and x−1} .
After the room temperature T _{start, j that} is close to the _normal room temperature T _normal at the time of the unit time j is determined, the room temperature adjustment operation planning unit 111 returns to step 245, does not exceed the peak power P _max , and is followed-up cooling In step 246 to step 250, an operation schedule of unit time j that makes time x minutes the longest is obtained.

If the room temperature change amount T _{j, x} due to follow-up cooling for x minutes of unit time j in step 249 is larger than the change from T _{start, j} to T _{normal, normal} room temperature T is obtained by follow-up cooling for x minutes. It is that it was lowered to _normal .
For this reason, the room temperature adjustment operation planning unit 111 first performs a follow-up cooling operation for x minutes in unit time j, and sets an operation schedule for performing a normal operation for (30−x) minutes (step 254).
By the steps 240 to 254, it is possible to plan an operation schedule for the follow-up cooling / follow-up heating period.
As shown in FIG. 16, the planned operation schedule gradually decreases the room temperature, which has been raised by stopping the air conditioner during the power suppression period, into a plurality of unit times.
Further, as shown in FIG. 17, the follow-up cooling time x is adjusted so that the demand power for each unit time in the follow-up cooling / follow-up heating period does not exceed the peak power _Pmax .

  When the power suppression operation plan and the follow-up cooling / follow-up heating operation plan during the follow-up cooling / follow-up heating are completed, the operation schedule generation unit 112 performs a day operation based on the operation schedules of the power suppression period and the follow-up cooling / follow-up heating period. An operation schedule is generated (step 200).

Thus, in the post-chase cooling, so is not impaired comfort by too high a room temperature by stopping the excess air conditioner, to set the upper limit value T _max to room temperature be raised by the stop of the air conditioner, the T _normal The room temperature is maintained within the range of _Tmax .
The difference from the case of utilizing pre-cooling is that a room temperature maintenance operation is performed in order to maintain the room temperature raised by the stop of the air conditioner.
The room temperature maintaining operation in the case of the follow-up cooling is an operation in which the set temperature is increased in order to maintain a room temperature higher than the _normal T _normal , so that the demand power is reduced compared to the normal operation. It differs from the case of using pre-cooling during operation.

In addition, as shown in FIGS. 29 and 30, it is possible to suppress the peak power of the day by using both pre-cooling and follow-up cooling.
When using both pre-cooling and follow-up cooling, the lower limit value T _min is set to the room temperature lowered by the pre-cooling, and the upper limit value T _max is set to the room temperature raised by the stop of the air conditioner.
Then, at room temperature adjustment period as shown in FIG. 29, the pre-cooling the room temperature _{T normal} to _{T min.}
In the power suppression period, the air conditioner is stopped until the room temperature is increased from _Tmin to _Tmax .
In the follow-up cooling / follow-up heating period, follow-up cooling is performed in order to lower the room temperature from _Tmax to _Tnormal .
In this way, it is possible to suppress the peak power as shown in FIG. 30 while keeping the room temperature between T _min and T _max .
In the present embodiment, the case where pre-cooling or follow-up cooling is used in the cooling operation timing has been described as an example, but it is also possible to suppress peak power by using pre-heating or follow-up heating during the heating operation timing.
Follow-up heating means that the air conditioner is stopped during the power suppression period, and heating is strengthened during each unit time of the follow-up cooling / follow-up heating period after the power suppression period. This is a peak shift technique for returning to _normal room temperature T _normal .

*** Explanation of the effect of the embodiment ***
Thus, according to Embodiment 1, the effect of precooling / preheating using the room temperature maintenance operation is divided into a plurality of unit times.
Thereby, it is possible to suppress power in a plurality of unit times instead of suppressing power in one unit time.
Also, during precooling / preheating, precooling / preheating is performed in a plurality of unit times using a room temperature maintenance operation.
Accordingly, it is possible to perform precooling / preheating in a plurality of unit times instead of precooling / preheating in one unit time.
By suppressing power and pre-cooling / pre-heating in multiple unit times, even when the demand power of the unit time around peak power is large, the peak power is suppressed while keeping the room temperature within the user's tolerance and maintaining comfort. It becomes possible to do.
