Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a demand control system, a demand control method, a demand control management apparatus, and a demand control management method for electrical equipment.
[0002]
[Prior art]
For example, the air conditioner consumes a large amount of power at the time of peak power consumption such as a hot day in summer. At the time of such power consumption peak, significant power saving can be achieved only by raising the set temperature of the air conditioner by 2 to 3 ° C. In consideration of this, DSM (Demand Side Management) is proposed in which a power company or the like adjusts the power consumption of electric devices (including air conditioners) such as homes and office buildings by remote control. Specifically, a demonstration test of the DSM service has been started in Tokyo in November 1999 by the industry group “Echonet Consortium” for home appliance control.
[0003]
In this demonstration test, as shown in FIG. 11, a plurality of air conditioners 2 a to 2 f are installed in the model house 1 for the demonstration test, and the set temperature of these air conditioners 2 a to 2 f can be centrally managed by the controller 3. Further, the controller 3 is connected to a predetermined network 4 such as an ISDN (Integrated Services Digital Network) line network or a PHS (Personal Handyphone System) line network. Then, by transmitting a control signal from the power company server 5 to the controller 3 of the demonstration test model house 1 through the network 4, each air conditioner 2a to 2f can be remotely operated from the power company server 5. It has become.
[0004]
Information relating to the driving status of each of the air conditioners 2a to 2f (for example, whether or not the air conditioner is operating, room temperature information, humidity information, etc .; hereinafter referred to as “driving status information”) is transmitted to the controller via the local communication line 6. The controller 3 autonomously performs drive control of each of the air conditioners 2a to 2f based on the drive status information.
Thereby, by remote control from the server 5 of the electric power company, it is possible to turn off the air conditioners 2a to 2f or change the set temperature to save power.
[0005]
[Problems to be solved by the invention]
In the demonstration experiment described above, the DSM method is applied to a single demonstration test model house 1, and this method is referred to as various actual facilities such as office buildings or commercial store facilities (hereinafter referred to as “property”). ), Power saving is performed in a wide area, so the problem is how to efficiently reduce the power consumption of each property.
[0006]
By the way, when the control signal is transmitted from the server 5 of the power company to the controller 3 of each property, if the power consumption is uniformly limited for all the air conditioners 2a to 2f, the power consumption can be reduced to any level. The problem is whether to converge.
[0007]
For example, if the power consumption is set to be extremely low by remote control, for example, in each property, the cooling effect etc. is limited in spite of extreme heat, and comfortable air conditioning is achieved. As a result, it becomes impossible to provide a comfortable service to the users of the air conditioners 2a to 2f.
[0008]
On the other hand, if the power consumption controlled by remote control is set high for the purpose of ensuring the effect of cooling or the like for the user, it will be difficult to ultimately achieve the desired power saving of the power company.
[0009]
However, in the method shown in FIG. 11, since the driving status of each of the air conditioners 2a to 2f has not been transmitted to the electric power company in real time, what level of power consumption should be converged in the past Therefore, it is difficult to reflect the actual operation status of each of the air conditioners 2a to 2f in real time without relying on a numerical value or the like determined in advance based on the above statistics. Therefore, it was practically difficult to save power to a desired level while performing comfortable air conditioning according to the actual situation.
[0010]
Therefore, an object of the present invention is to provide a demand control system, a demand control method, a demand control management device, and a demand control management method for an electric device that can save power to an appropriate level in accordance with the actual operating state of each air conditioner. It is to provide.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a block diagram showing a demand control system for electrical equipment according to an embodiment of the present invention. In addition, in FIG. 1, the distribution line for supplying electric power to the air conditioner 12 of each property 11a-11d from the electric power company as an electric power supply source is abbreviate | omitting illustration. And in this embodiment, the example which applied the air conditioner as an electric equipment is demonstrated. Moreover, as a property 11a-11d demonstrated in this embodiment, a factory, a building, a house, a school, an apartment, etc. are applied, for example.
[0022]
FIG. 2 is a block diagram showing the configuration of the air conditioner 12 taking the one property 11d as an example. Similarly, in the properties 11a to 11c, a plurality of air conditioners 12 are connected to the controllers 13a to 13c.
[0023]
As shown in FIG. 2, the air conditioner 12 in each property 11 a to 11 d processes drive status information in various drive systems 21 including a compression device and a blower device and predetermined various sensors (not shown). Based on this, a control unit 22 that controls the drive system 21 and a communication circuit 23 that transmits the drive status information to the controllers 13a to 13d are provided. The control unit 22 uses a microcomputer chip including a ROM, a RAM, and a CPU (not shown), and functions when the CPU operates in accordance with a software program stored in the ROM in advance. Based on the control instruction signal given from the controller 13a through the communication circuit 23, the control unit 22 performs on / off switching, change of the set temperature, change of the set humidity, change of the air flow, etc., and drive control of the drive system 21. To do. The control unit 22 transmits the drive control status of the drive system 21 to the controllers 13a to 13d as drive status information through the communication circuit 23.
[0024]
As shown in FIG. 1, the controllers 13a to 13d are specifically monitoring boards that are unified in the respective properties 11a to 11d, and microcomputer chips including a ROM, a RAM, and a CPU (not shown) are used. The CPU operates in accordance with a software program stored therein, and includes a MODEM (Modulator-Demodulator) or TA (Terminal Adapter) for connection to the large-scale network 14.
[0025]
The controllers 13a to 13d transmit control instruction signals for instructing each air conditioner 12 to perform drive control of the drive system 21 in accordance with an operation on a predetermined operation panel (not shown). Further, the driving state information given from each air conditioner 12 is collected and transmitted to the centralized calculation center 15 through a predetermined large-scale network 14 such as an ISDN line network or a PHS line network.
[0026]
The centralized calculation center 15 is equipped with a CPU, ROM, and RAM, and uses a computing system having a communication circuit such as MODEM or TA that can be connected to the large-scale network 14, and a predetermined storage device such as a hard disk drive. The CPU operates in accordance with a software program stored in advance. The centralized calculation center 15 is connected to the controllers 13 a to 13 d of the properties 11 a to 11 d through the large-scale network 14 and is connected to the server 16 of the electric power company through a predetermined line 25.
[0027]
And the centralized calculation center 15 is based on the drive condition information of the air conditioner 12 given from each property 11a-11d through the large-scale network 14, and in all the properties 11a-11d connected to the large-scale network 14. The power consumption related to the air conditioner 12 is totaled, and the total result is transmitted to the server 16 of the power company that is the power supply source.
[0028]
Based on the total result, the electric power company transmits a request (hereinafter referred to as “peak cut request”) to limit the power consumption to the centralized calculation center 15 via the server 16 or further the cancellation thereof. In addition, the centralized calculation center 15 operates the air conditioner 12 while suppressing the power consumption to a predetermined value or less to the controllers 13a to 13d of the properties 11a to 11d through the large-scale network 14 based on the peak cut request. The peak cut command to be calculated is transmitted.
[0029]
The controllers 13a to 13d perform capacity control of the outdoor unit (compressor) of each air conditioner 12, set temperature control in the indoor unit, compressor OFF control, and the like according to the given peak cut command.
[0030]
An operation of the demand control system for such an electric device will be described.
[0031]
First, the actual driving status of each air conditioner 12 is transmitted as driving status information to the controllers 13a to 13d in each property 11a to 11d, and is aggregated from the controllers 13a to 13d to the centralized calculation center 15 through the large-scale network 14. To send.
[0032]
In the centralized calculation center 15, after grasping the drive status information of all the air conditioners 12 collected by the controllers 13a to 13d, the power consumption related to the air conditioners 12 in the area where the large-scale network 14 is laid is totaled. The total result is transmitted to the server 16 of the electric power company.
[0033]
The server 16 of the electric power company transmits a peak cut request to the centralized calculation center 15 as appropriate by looking at the total result of the power consumption. The centralized calculation center 15 transmits a peak cut command and cancellation thereof to the controllers 13a to 13d of the properties 11a to 11d through the large-scale network 14 based on the peak cut request and cancellation given from the server 16 of the electric power company. To do. Each controller 13 a to 13 d instructs drive control of each air conditioner 12 based on a peak cut command given from the centralized calculation center 15.
[0034]
As described above, by performing peak cut at each property 11a to 11d based on the peak cut command from the centralized calculation center 15, a large peak cut can be performed in real time as an area managed by the centralized calculation center 15. it can.
[0035]
And communication between the centralized calculation center 15 and each property 11a-11d is made bidirectional, and while the centralized calculation center 15 monitors the power consumption of each property 11a-11d, the controllers 13a-13d for each property 11a-11d. Since the operation of the air conditioner 12 is controlled, it is possible to perform power saving to an appropriate level according to the actual operating state of each air conditioner 12 while having a wide scale of the large-scale network 14. . Therefore, there is an advantage that the sacrifice of comfort can be minimized while implementing power saving as much as possible and realizing a reduction in the power company's reliable excessive capital investment by power peak cut.
[0036]
Moreover, if it is an electric power company, compared with the case of the verification test shown in FIG. 11, the peak cut request of the whole area which the central calculation center 15 has jurisdiction does not need to perform remote control separately for every property 11a-11d. Is transmitted to the centralized calculation center 15, and the centralized calculation center 15 then issues a peak cut command for the power consumption of all the properties 11a to 11d, which is convenient because the power company does not have to perform complicated individual remote control. It is.
[0037]
Hereinafter, specific examples will be described.
[0038]
<Example 1>
An example of a method for transmitting a peak cut command from the centralized calculation center 15 to the controllers 13a to 13d of the properties 11a to 11d through the large-scale network 14 will be described.
[0039]
In general, it is said that if the air conditioner is repeatedly turned off for 3 minutes and turned on for 7 minutes at the peak of power consumption in summer, energy saving is 30%. Moreover, it is said that if the air conditioner is stopped within 3 minutes, the comfort is not impaired. Considering this, if the power control of the air conditioner is performed in the whole area for about 3 minutes per 10 minutes, the generated power can be significantly reduced without impairing the comfort in each property.
[0040]
Here, as specific peak cut command methods in the centralized calculation center 15, there are a cyclic command method (first peak cut command method) and a level-specific command method (second peak cut command method) for each group. is there.
[0041]
In the cyclic command method, as shown in FIG. 3, many properties 11a to 11d are classified into four groups (groups A to D) according to areas such as addresses where the properties 11a to 11d are located. Demand control instructions are given to (rank rotation). That is, for example, first, a peak cut command (portion described as “control”) is given to the group A (region A) for a few minutes, and the peak cut command for the group A is canceled almost simultaneously or before and after. , A peak cut command (control) for group B (region B) is given. Similarly, the peak cut command (control) of group C (region C) is given when the peak cut command for group B is released, and group D (region D) is issued when the peak cut command for group C is released. The peak cut command (control) for group A is given when the peak cut command for group D is canceled. At this time, for example, as described above, the peak cuts of the air conditioners 12 of the groups A to D are performed for about 3 minutes in 10 minutes.
[0042]
Further, as shown in FIG. 4, the level-specific instruction method classifies the acceptance level for the peak cut for each property 11a to 11d according to the content of the contract made in advance with the user of each property 11a to 11d. For example, it is classified into four groups (groups A to D) according to the level. Then, the time during which peak cut control is continued is changed according to the level of each group A to D. Specifically, the peak cut control time is set to be the longest for group A, and the peak cut control time is set to be the shortest for group D.
[0043]
The procedure for performing demand control by appropriately selecting two methods, the cyclic command method and the level-specific command method, is shown in the flowchart of FIG. 5 and the timing chart of FIG. In addition, in this flowchart and timing chart, in the initial stage of each property 11a-11d, each controller 13a-13d autonomously sets each air conditioner 12 until the peak cut command is given from the centralized calculation center 15. It is assumed that the drive control is instructed. Further, the centralized calculation center 15 calculates the total power consumption based on the driving condition information of each air conditioner 12 given from the controllers 13a to 13d of the respective properties 11a to 11d, and real-time to the server 16 of the power company. Assume that you are sending in.
[0044]
First, at step S01 in FIG. 5 and time T01 in FIG. 6, when the power consumption summed up by the centralized calculation center 15 is likely to exceed the allowable amount of power generated by the electric power company, the sign ts in FIG. When the total power consumption is likely to exceed the allowable amount Lv of the transformer capacity of the power company as in the time zone shown in FIG. 1, first, a peak cut request is made from the power company server 16 to the centralized calculation center 15. (T02).
[0045]
Then, at step S02 in FIG. 5 and time T03 in FIG. 6, the central calculation center 15 issues a peak cut command to each of the properties 11a to 11d through the large-scale network 14. At this time, the centralized calculation center 15 selects a cyclic command method (step S03) and a level-specific command method (step S04) by a predetermined button operation or the like.
[0046]
Then, in step S05 of FIG. 5, peak cut control (demand control) is implemented in each property 11a-11d.
[0047]
Here, as a method of reducing the power consumption in each property, for example, the power consumption of the outdoor unit (compressor) of each air conditioner 12 is reduced to about 0% to 70%, or the set temperature of the indoor unit Or the compressor is completely turned off to stop the driving of each air conditioner 12.
[0048]
In this case, it is necessary to repeat the peak cut control and the cancellation thereof as shown in FIG. 3 in the cyclic command method and as shown in FIG. 4 in the level command method. Therefore, by repeatedly receiving the peak cut command (time T03, T06, T09 in FIG. 6) and the cancellation command (time T04, T07 in FIG. 6) from the centralized calculation center 15, each controller 13a- 13d intermittently performs peak cut control of each air conditioner 12.
[0049]
The amount of reduction in power consumption at this time is not adjusted autonomously on the air conditioner 12 or the controllers 13a to 13d side, but is controlled depending on the peak cut command from the centralized calculation center 15. . However, during the peak cut control, the driving status of each air conditioner 12 is transmitted as driving status information from the controllers 13a to 13d to the centralized calculation center 15 through the large-scale network 14, and the centralized calculation center 15 saves power. Are collected and transmitted to the server 16 of the electric power company. Therefore, it is possible to know in real time how much power saving has been achieved by the server 16 of the power company.
[0050]
Next, when the electric power company determines that the peak cut control has been sufficiently performed based on the power saving information given from the centralized calculation center 15, steps S 06 in FIG. 5 and FIG. At time T10, the centralized calculation center 15 is requested to cancel the demand command from the server 16 of the power company. The centralized calculation center 15 instructs each of the properties 11a to 11d to cancel the peak cut control at step S07 in FIG. 5 and time T11 in FIG. And in Step S08 of Drawing 5, controllers 13a-13d of each article 11a-11d cancel peak cut control (demand control) to each air conditioner 12.
[0051]
As described above, in this embodiment, after the power company makes a peak cut request to the centralized calculation center 15, the centralized calculation center 15 alternately performs the peak cut command and the cancellation thereof to achieve appropriate power saving. it can.
[0052]
<Example 2>
In this embodiment, each of the properties 11a to 11d has a heat storage air conditioner or a power storage air conditioner in advance.
[0053]
FIG. 8 shows the temporal transition of power consumption per hour in each property 11a to 11d such as a store. Here, symbol Th in FIG. 8 indicates the reference power amount. When the power consumption per hour is realized exceeding the reference power amount Th, the amount R1 exceeding the reference power amount is paid to the power company. This shows the level of increase in electricity charges. Further, the reference numerals in FIG. 8 indicate time periods when the electricity rate is increased at noon regardless of the power consumption.
[0054]
For example, during midsummer time, as shown in FIG. 8, the power consumption tends to reach a peak at midday and evening. Accordingly, in each of the properties 11a to 11d, the air conditioner is driven by using the energy stored in the heat storage air conditioner or stored in the energy storage air conditioner at noon and evening, whereby the noon and evening hours are driven. It is desirable to perform peak cutting.
[0055]
In this embodiment, when the power demand is tight and the central calculation center 15 receives a peak cut request from the server 16 of the electric power company, the central calculation center 15 sends it to the controllers 13a to 13d of the properties 11a to 11d. Issue a peak cut command.
[0056]
The controllers 13a to 13d of the respective properties 11a to 11d change the heat storage / storage control schedule of each air conditioner 12 based on the peak cut command given from the centralized calculation center 15, and are already at noon and evening. It changes so that peak cut operation may be implemented using the energy stored in the heat storage air conditioner or stored in the power storage air conditioner. Each air conditioner 12 performs peak cut according to control by the controllers 13a to 13d.
[0057]
In this case, for example, a normal user has already stored heat in the heat storage air conditioner or stored air conditioning for the time zone R2 at midday or for the amount R1 in which the power consumption per hour exceeds the reference power amount Th in the evening. Since the electric power is consumed using the energy stored in the machine, the electric power supplied from the electric power company is not used. Therefore, users in each property 11a to 11d are not charged an additional fee even if they consume power exceeding the reference power amount Th in the evening or at noon according to a special contract with the power company. That's it.
[0058]
<Modification>
In the above-described embodiment, an air conditioner has been described as an example of an electric device.
[0059]
In the above embodiment, the power consumption totaled by the centralized calculation center 15 is transmitted to the power supply source. However, when the power supply source can grasp the power consumption of the entire region in real time, it is not necessarily the centralized calculation. It is not necessary to disclose the total result from the center 15 to the power supply source.
[0060]
Further, in the first embodiment, the cyclic command method grouped for each region and the level-specific command method for setting the level according to the contract with the user have been described. However, as a grouping method, grouping can be performed according to other criteria. You may go. For example, when the power consumption of each property 11a to 11d is tabulated at the centralized calculation center 15, properties 11a to 11d with particularly large power consumption are extracted at the centralized calculation center 15, and power is supplied to the properties 11a to 11d. A peak cut request may be issued preferentially from the server 16 of the supply source. Alternatively, grouping may be performed randomly.
[0061]
Alternatively, in the first embodiment, the cyclic instruction is performed by grouping on the basis of the area. However, after grouping on the basis of the area, according to the weather and temperature of the area to which each group belongs. The priority order for performing the peak cut command may be determined as a level, and the level-specific command may be performed according to this level. As a result, for example, during peak power consumption in summer, a peak cut command is given to a group of areas with relatively low temperatures or high precipitation with a longer peak cut control duration. Then, peak cut control according to the actual situation for each region can be performed.
[0062]
In addition, as a grouping standard, for example, a factory, a restaurant, an office, a general household, or the like may be used.
[0063]
In the above embodiment, the power company is applied as a representative example of the power supply source. However, as the power supply source, an individual distributed power generation company (IPP) other than the power company is provided in parallel with the power supply from the power company. ) May be used for power supply. Since the centralized calculation center 15 performs a peak cut command on each of the properties 11a to 11d, the centralized peak cut command is efficiently performed even when power is supplied from a plurality of power supply sources. be able to.
[0064]
In this case, when power is supplied from a plurality of power supply sources, initially, the power supply is performed from a relatively inexpensive power supply source (hereinafter referred to as “initial power supply source”), When the total power consumption of each air conditioner 12 at the centralized calculation center 15 exceeds the power supply limit of the initial power supply source, supply power from other power supply sources for which expensive power charges are set. It is also possible to do so.
[0065]
In this way, by calculating the total power consumption of each air conditioner 12 at the centralized calculation center 15, it is possible to reduce as much as possible the power charge borne by the user. Therefore, it is possible to increase the incentive for the user to use this demand control system, and it is possible to achieve a reduction in power consumption in the entire area under the control of the centralized calculation center 15.
[0066]
Furthermore, in the first embodiment, in step S06 and step S07 in FIG. 5, the peak cut request is canceled from the power supply source server 16 to cancel the demand control. The centralized calculation center 15 autonomously predicts the peak cut time based on the information held by the centralized calculation center 15 without requiring a request from the server 16 of the power supply source, and performs demand control of each property 11a to 11d. May be commanded.
[0067]
Specifically, as shown in FIG. 9, a peak cut request is sent from the power supply server 16 to the centralized calculation center 15 in step S11, and the peak cut time is predicted in the centralized calculation center 15 in step S12. At this time, the central calculation center 15 predicts the total power reduction amount of all the properties 11a to 11d from a power consumption obtained using a neural network or the like using a predetermined arithmetic expression, and further calculates a predetermined arithmetic expression. Use to calculate the required peak cut time.
[0068]
In step S13, a peak cut command is transmitted from the centralized calculation center 15 to each of the properties 11a to 11d. At this time, as described in the first embodiment, either the cyclic command method (step S14) or the level-specific command method (step S15) is selected and adopted. And in step S16, demand control is performed in each property 11a-11d.
[0069]
Thereafter, when the peak cut time predicted in step S12 is reached, the central calculation center 15 instructs each of the properties 11a to 11d to cancel the peak cut control (step S17). As a result, demand control is canceled in each of the properties 11a to 11d (step S18). According to this procedure, since it is not necessary for the power supply source to instruct the centralized calculation center 15 to cancel the demand control, the burden on the power supply source is reduced.
[0070]
Alternatively, in the controllers 13a to 13d of the properties 11a to 11d, when a peak cut request is given from the centralized calculation center 15, the repetition cycle of execution and cancellation of demand control is changed according to the peak cut request. It may be programmed. In this case, as shown in FIG. 10, after a peak cut request is sent from the power company to the central calculation center 15 at time T21 and the central calculation center 15 issues a peak cut command to each of the properties 11a to 11d at time T22, At time T23, until the centralized calculation center 15 instructs each of the properties 11a to 11d to cancel the execution of demand control, the controllers 13a to 13d of the properties 11a to 11d autonomously repeat the execution and cancellation of demand control. Will do. Therefore, signal transmission from the power company and the centralized calculation center 15 can be largely omitted, and communication efficiency can be improved.
[0071]
Furthermore, although the above embodiment has been described by taking the monitoring panel as an example of the controllers 13a to 13d, for example, a remote controller may be used.

【The invention's effect】
According to the demand control system, the demand control method, the demand control management device, and the demand control management method of the electric equipment according to the present invention, the power consumption of each property (11a to 11d) is obtained by the centralized calculation center (15). Since the power supply source (16) does not directly control the individual power consumption of each property, power saving can be easily performed for a plurality of properties managed by the centralized calculation center. it can.
[0073]
And Electrical equipment Since the information on the driving status of (12) is collected in the centralized calculation center (15) by transmission from the controllers (13a to 13d) of the respective properties (11a to 11d), Electrical equipment Information from the centralized calculation center (15) is sent to the power supply source (16) for presentation, or the centralized calculation center autonomously determines the power consumption of each property based on this driving status information. By giving reduction instructions, Electrical equipment It is possible to save power to an appropriate level according to the operating status of the system. Therefore, there is an advantage that the sacrifice of comfort can be suppressed to a minimum while reducing the excessive capital investment by implementing the power saving as much as possible and the power company's reliable power peak cut.
[0074]
In addition, since a plurality of properties are controlled by being classified into several groups, power saving according to the characteristics of each group can be implemented.
[0075]
For example, when grouping by location area, it is possible to set a priority order for performing peak cut commands according to the weather and temperature in the region to which each group belongs, and to perform level-specific commands according to this level. For example, if the peak cut control is given to a group in a region with relatively low temperature or a high amount of precipitation with a longer duration of peak cut control, for example, during peak power consumption in summer, The peak cut control according to the actual situation for each region can be performed.
[0076]
Alternatively, if grouping is performed according to the power consumption amount of the electrical equipment, it is possible to perform power saving that finely corresponds to the power consumption of each electrical equipment.
[0077]
Here, if the centralized calculation center directs the control of the power consumption for each property and the cancellation of the control based on the request from the power supply source, all the power supply sources can manually save power. it can.
[0078]
For example, if the centralized calculation center instructs the control of intermittent and intermittent power consumption by repeatedly instructing the execution and release of control, it is comfortable for the user while reducing the power consumption. It is possible to control so as not to damage.
[0079]
Alternatively, if the intermittent power consumption is controlled intermittently by repeatedly executing and releasing the control by the controller in each property, it is not necessary to give an instruction every time the control is executed and released. Thus, the amount of communication can be reduced.
