<First Embodiment>
The power management apparatus according to the present embodiment generates an operation schedule of at least a part of a plurality of loads used within a predetermined power consumption unit so that the total of these power consumptions does not exceed a predetermined threshold. Means. Some of the loads are used relatively regularly. The power management apparatus according to the present embodiment creates such a load operation schedule so that the total power consumption of such loads does not exceed a predetermined value. That is, the total power consumption of such loads is leveled. This is expected to suppress inconvenience that the total power consumption within a predetermined power consumption unit exceeds a predetermined value. Details will be described below.

First, an application example of the power management apparatus 1 of the present embodiment will be described with reference to FIG. The power management system of this embodiment includes at least a power management device 1. The power management system may further include at least one of the power storage system 2, the server 4 (example: cloud server), and the monitoring device 6.

The power management device 1, the power storage system 2, and the monitoring device 6 are provided for each predetermined unit (power consumption unit) that consumes power.

The power consumption unit is, for example, a door unit (for example, a unit of a detached house, a unit of an apartment, an apartment, etc.), a facility unit (for example, an apartment unit, an apartment unit, a building unit, a factory unit, a store unit, an amusement facility unit, etc.) Units obtained by arbitrarily subdividing these units (eg, one or more floor units such as buildings, condominiums, apartments, etc.), and group units (eg: multiple apartments, buildings, apartments, etc.) in which these are arbitrarily combined Unit)).

FIG. 2 shows an example of a configuration diagram corresponding to one power consumption unit. The power management apparatus 1, the power storage system 2, and the monitoring apparatus 6 are connected to each other via a communication network 200 configured by wire and / or wireless so that they can communicate with each other. The power management device 1, the power storage system 2, the server 4, and the monitoring device 6 are connected to each other via a network 5 such as the Internet and can communicate with each other. Furthermore, the power management device 1 and / or the monitoring device 6 and at least a part of the load 3 may be communicable via wire and / or wireless.

The unit power network 100 is a dedicated power wiring network provided for each power consumption unit, and corresponds to, for example, indoor wiring provided in each door, premise wiring provided in each facility, and the like. The unit power network 100 is connected to a commercial power source via a power receiving point. Power is supplied from the commercial power source to the unit power network 100 via the power receiving point.

The power storage system 2 is connected to the unit power network 100. Then, power is supplied from the power storage system 2 to the unit power network 100 (discharge of the power storage system 2), or power is supplied from the unit power network 100 to the power storage system 2 (charging of the power storage system 2).

In addition, a plurality of loads 3 are connected to the unit power network 100. The load 3 may be a home appliance such as an air conditioner, a refrigerator, or a television, may be a commercial product such as a commercial refrigerator or a commercial air conditioner, or may be a machine used in a factory. Good. Electric power is supplied from the unit power network 100 to the load 3, and the load 3 operates.

The monitoring device 6 operates by receiving power supply from the unit power network 100, for example. The monitoring device 6 monitors the power consumption status within the power consumption unit. For example, the monitoring device 6 communicates with a measurement sensor (not shown) installed near the power receiving point, and monitors the instantaneous value of the total power consumption and / or the total current consumption within the power consumption unit.

Further, the monitoring device 6 may monitor and control the operating state of each load 3. For example, the monitoring device 6 may monitor whether each of the plurality of loads 3 is in a power-on state or an off-state, and may create and store a usage record indicating an operation state at each time. Further, such usage records may be transmitted to the server 4 and accumulated by the server 4. The usage record may be accumulated in association with attributes of the day (eg, month, day of the week, date, weather, temperature, humidity, season, etc.).

There are various means for monitoring the operating state of each load 3. For example, a measurement sensor may be installed for each predetermined load 3. And the monitoring apparatus 6 may identify an operation state based on the instantaneous value of the power consumption and / or current consumption of each load 3 which were acquired from the said measurement sensor. For example, when the instantaneous value is greater than or equal to a predetermined value, the power supply may be specified, and when the instantaneous value is less than the predetermined value, the power supply may be specified. In addition, the technology disclosed in Japanese Patent No. 3403368 may be used. In this technique, the characteristic amount of the measurement data during operation of each of the plurality of loads 3 is stored in advance. Then, when the instantaneous value of the power consumption and / or current consumption of the entire unit power network 100 is measured near the power receiving point, the feature amount extracted from the measurement data and the feature amount arbitrarily combining the feature amounts of the plurality of loads 3 Are identified, for example, to identify the load 3 operating at each time point.

The monitoring device 6 and / or the power management device 1 may control the operation (power ON / OFF) of each of the plurality of loads 3. That is, the monitoring device 6 and / or the power management device 1 may transmit a power-on instruction input and a power-off instruction input to the load 3 by wired and / or wireless communication. Then, the load 3 may execute power ON / OFF based on the power ON instruction input and the power OFF instruction input received from the monitoring device 6 and / or the power management device 1.

The power management device 1 operates by receiving power supply from the unit power network 100, for example. The power management device 1 is based on information acquired from the server 4 or the monitoring device 6 or information input to the power management device 1 from the user, and at least a part of the plurality of loads 3 connected to the unit power network 100. The operation schedule is generated so that the sum of these power consumptions does not exceed a predetermined threshold.

Next, the configuration of the power management apparatus 1 will be described in detail. FIG. 12 shows an example of a functional block diagram of the power management apparatus 1 of the present embodiment. As illustrated, the power management apparatus 1 includes an acquisition unit 10 and a determination unit 20. The determining unit 20 includes a temporary determining unit 21, a specifying unit 22, an extracting unit 23, and a correcting unit 24.

The acquisition unit 10 acquires candidate time zone information indicating a candidate time zone to be operated corresponding to each of the plurality of loads 3. The acquisition unit 10 acquires candidate time zone information corresponding to each “load 3 to be controlled” that is at least a part of the plurality of loads 3 connected to the unit power network 100.

Some of the loads 3 are used at a fixed timing each time. For example, in ordinary households, the load 3 such as an air conditioner or a TV is turned on every day, immediately after getting up, or when returning home, and at a predetermined time such as leaving the house or going to bed for work. The load 3 may be turned off. Further, in a facility such as a factory, the power source of the load 3 such as a machine may be turned on every day at a predetermined time before the start time, and the power source of the load 3 may be turned off at the end time.

The load 3 that is used relatively regularly as described above can be referred to as “the load 3 to be controlled”. FIG. 4 schematically shows control target load information including information for identifying the control target load 3. As shown in the figure, the control target load information includes identification information of each load 3 to be controlled. Each identification information is associated with the power consumption (representative value) of each load 3 to be controlled. Each identification information may be associated with the current consumption (representative value) of each load 3 to be controlled (not shown).

Control target load information is registered in the power management apparatus 1 in advance. For example, a user corresponding to each unit power network 100 may determine the load 3 to be controlled and input it to the power management apparatus 1. The user can register, in the power management apparatus 1, the load 3 that is relatively regularly used among the plurality of loads 3 used by the user as the load 3 to be controlled. At this time, the user may input the power consumption of each load 3, or the power management apparatus 1 may inquire the server 4 about the power consumption of the load 3 to be controlled and obtain it from the server 4.

In addition, the power management device 1, the server 4, or the monitoring device 6 may analyze the past usage record of each load 3, and may extract the load 3 that is used relatively regularly. Then, the extracted load 3 may be registered in the power management apparatus 1 as the load 3 to be controlled.

The method for determining whether or not the information is used relatively regularly is not particularly limited, but may be determined based on, for example, the degree of coincidence calculated by an arbitrary algorithm. Hereinafter, although an example is demonstrated, it is not limited to this.

For example, any one day of data of past usage records over a plurality of days for a certain load 3 is used as representative data, and a pair of the representative data and each other day of data for the load 3 is represented as a pair. In comparison, the time H1 (unit: hour, minute or second) in which the power is on is calculated and the time H2 (unit: hour, minute or second) in which only one of the power is on is calculated. To do. Next, H1 / (H1 + H2) is calculated for each pair. When the representative values (eg, statistical values such as maximum value, minimum value, mode value, average value, etc.) of a plurality of H1 / (H1 + H2) calculated for each pair are equal to or greater than a predetermined value, the load 3 is compared. It is judged that it is used regularly and regularly.

Note that the above calculation may be performed a plurality of times by changing the representative data, instead of using only one representative data. If the representative value of a plurality of values obtained by a plurality of calculations (eg, statistical values such as maximum value, minimum value, mode value, average value, etc.) is equal to or greater than a predetermined value, the load 3 is relatively You may judge that it is used regularly.

Also, the usage pattern of the load 3 can change according to the attributes of the day (eg, month, day of the week, date, weather, temperature, humidity, season, etc.). Therefore, in determining whether or not the data is used comparatively regularly, the above determination is not made based on all the data of past usage records of a certain load 3, but only on a part of data having a predetermined attribute in common. You may go. For example, the above determination may be made based only on data belonging to one of Monday through Friday.

Next, FIG. 5 schematically shows an example of candidate time zone information indicating candidate times for operating each of the loads 3 to be controlled determined in this way. The acquisition unit 10 acquires such information.

In FIG. 5, load ID, operation time zone candidate (candidate time zone information), operation rate (operation rate information), operation time (operation time information), and continuous use time (continuous operation time information) are associated with each other. The load ID is information for identifying each of the loads 3 to be controlled. The operation time zone candidate is a time candidate for operating each of the loads 3 to be controlled. The operation ratio indicates the ratio of “time when the load 3 should be operated (operation time)” to “total time of candidate times indicated in the operation time zone candidates”. The operation time indicates a time (hour / day) during which the load 3 should be operated within a predetermined unit period (one day in the figure). The continuous use time indicates a time during which each load 3 is used continuously.

For example, according to the information shown in FIG. 5, the load 3 to be controlled with the load ID “00001” has operating time zone candidates from 5:00 to 10:00 and from 19:00 to 24:00, of which 70% It should be understood that the time should be up. Further, it can be seen that the load 3 to be controlled should be operated for 7 hours in one day, and the time for continuous use is 2 hours.

Also, it can be seen that the load 3 to be controlled with the load ID “00002” is the candidate for the time zone to be operated from 0:00 to 24:00, and should be operated for 100% of the time. Further, it can be seen that the load 3 to be controlled should be operated for 24 hours in one day, and the continuous use time is 24 hours.

Although the information shown in FIG. 5 is in units of one day, the acquisition unit 10 may acquire information in other period units. For example, a half day unit, a week unit, etc. can be considered. In the case of a weekly unit, the candidate time zone information is information indicating candidates that specify the day of the week and the time zone to be operated.

As illustrated in FIG. 5, the acquisition unit 10 corresponds to each of the plurality of loads 3 to be operated, and includes at least one of the operation time information, the operation time information, and the continuous operation time information as well as the candidate time zone information. You may get one more.

As a modification example of these pieces of information, as shown in FIG. 6, the acquisition unit 10 corresponds to each load 3 to be controlled, among candidate time zone information, operation ratio information, operation time information, and continuous operation time information. Multiple sets of at least one set may be acquired. The candidate of the time zone in which the load 3 to be controlled is operated, the operation ratio, the operation time, the continuous use time, and the like can be changed according to the attribute of the day. Therefore, the acquisition unit 10 may acquire a plurality of sets corresponding to predetermined attributes.

For example, as illustrated in FIG. 6, the acquisition unit 10 may acquire a set for “Monday through Friday” and a set for “Saturday and Sunday”. In addition, although not illustrated, the acquisition unit 10 may acquire a set for “July to September and Monday to Friday” and a set for “July to September and Saturday and Sunday”. . In this case, as shown in FIG. 6, the attribute of the day is associated with each set. In addition, how to combine the attributes of the day is arbitrary.

Next, means for the acquisition unit 10 to acquire information as shown in FIGS. 5 and 6 will be described.

As an example, a user corresponding to each unit power network 100 determines values such as candidate time zone information, operation ratio information, operation time information, and continuous operation time information for each load 3 to be controlled, and inputs them to the power management apparatus 1. May be. In addition, the user may input a plurality of attributes and the set of the day in association with each load 3 to be controlled. And the acquisition part 10 may acquire these information input from the user.

As another example, the power management device 1, the server 4, or the monitoring device 6 analyzes past usage records of each load 3 to be controlled, and displays candidate time zone information, operation ratio information, operation time information, and continuous operation time information. The value of may be determined. In addition, the power management device 1, the server 4 or the monitoring device 6 divides the past use results into groups based on the attributes of the day, analyzes each group, and displays candidate time zone information, operation ratio information, operation time information, and A value such as continuous operation time information may be determined for each group (an example in which a plurality of sets are created). And the acquisition part 10 may acquire the information which the power management apparatus 1, the server 4, or the monitoring apparatus 6 produced | generated. Hereinafter, although the example of a process which determines the value of candidate time slot | zone information, operation ratio information, operation time information, and continuous operation time information based on a use track record is demonstrated, it is not limited to this.

For example, the power management device 1, the server 4, or the monitoring device 6 analyzes past usage records and identifies a time zone that is operating at a predetermined first probability (eg, 5 days / 10 days) or more. Also good. Then, the time zone may be set as a time zone candidate (candidate time zone information) for operating the load 3 to be controlled.

In addition, the power management device 1, the server 4 or the monitoring device 6 analyzes past usage records and specifies a time zone in which the power management device 1, the server 4 or the monitoring device 6 is operating with a predetermined second probability (eg, 7 days / 10 days) or more. Also good. And the total time of the said time slot | zone is good also as time (operating time information) which operates the said load 3 of the said operation | movement object. Note that the first probability <the second probability may be satisfied.

The power management apparatus 1, the server 4 or the monitoring apparatus 6 operates based on the total time of the “candidate for operating time zone” determined as described above and the “operating time” for the candidate total time zone. The ratio of time (operation ratio information) can be calculated.

In addition, the power management device 1, the server 4 or the monitoring device 6 analyzes the past usage record, and calculates all the continuously used time (eg, 35 minutes, 1 hour 10 minutes, 3 hours 45 minutes, etc.). You may specify. Then, they are grouped into predetermined time zones (for example, 0 to 30 minutes, 30 minutes to 1 hour 30 minutes, 1 hour 30 minutes to 2 hours 30 minutes), and representative values of the time zone with the most members (example: The intermediate value, the maximum value, and the minimum value may be used as continuous operation time (continuous operation time information).

Returning to FIG. 12, the determination unit 20 prevents the total power consumption or current consumption of the plurality of loads 3 to be controlled from exceeding a predetermined threshold based on the candidate time zone information of each of the loads 3 to be controlled. The operation schedule for each of the loads 3 to be controlled is generated. The determination unit 20 includes a provisional determination unit 21, a specification unit 22, an extraction unit 23, and a correction unit 24 in order to realize generation of the operation schedule.

The provisional determination unit 21 generates a first operation schedule for operating the load 3 for some or all of the time zone candidates to be operated for each load 3 to be controlled.

That is, the provisional determination unit 21 designates the operation time for the time specified by the operation ratio information or the operation time information in the candidate time zone specified by the candidate time zone information, and sets the first operation schedule. Is generated.

The acquisition unit 10 includes at least one of candidate time zone information, operation ratio information, operation time information, and continuous operation time information in association with each load 3 to be controlled as shown in FIG. When a plurality of sets are acquired, the tentative determination unit 21 identifies one corresponding set based on the attribute of the target day of the schedule (predicted value in the case of weather, temperature, humidity, etc.), and the identified set The first operation schedule can be generated based on the above.

Here, a specific example of generating the first operation schedule will be described using the example shown in FIG.

The load 3 to be controlled with the load ID “00001” has a duration of 7 hours on the day. The provisional determination unit 21 designates an operating time for 7 hours from 5 to 10 o'clock and 19:00 to 24:00, which are operation time zone candidates.

There are various designation methods. For example, the time to be operated is divided into arbitrary unit times (eg: 1 hour unit, 30 minute unit, 15 minute unit, etc.), and in any time zone for each unit time It may be allocated. In addition, when continuous use time is defined, the value of continuous use time is good also as the said unit time.

The method of allocating the unit time for the time to be operated to the candidate time zone is arbitrary. For example, the unit time may be allocated in order from the earliest time. In this case, the provisional determination unit 21 determines “operation time: from 5 o'clock to 10 o'clock and from 19 o'clock to 21 o'clock” as the first operation schedule of the load 3 to be controlled with the load ID “00001”.

In addition, when the electricity rate varies depending on the time, unit times corresponding to the time to operate may be allocated in order from the lowest electricity rate.

Next, the load 3 to be controlled with the load ID “00002” has a time to operate for 24 hours on that day, and the operation time zone candidates are from 0 to 24:00. In this case, the provisional determination unit 21 determines “operation time: 0:00 to 24:00” as the first operation schedule of the load 3 to be controlled with the load ID “00002”.

By such processing, the provisional determination unit 21 generates a first operation schedule as shown in FIG.

Returning to FIG. 12, the specifying unit 22 is a time when the total power consumption or current consumption of the plurality of loads 3 to be controlled exceeds a predetermined threshold when the first operation schedule generated by the provisional determination unit 21 is followed. A band (threshold overtime period) is specified.

The predetermined threshold value is the maximum power and / or maximum current that can be supplied from the commercial power source to the unit power network 100, the maximum power and / or maximum current that can be supplied from the power storage system 2 to the unit power network 100, and the load 3 connected to the unit power network 100. Can be arbitrarily determined based on the total power consumption and / or the ratio of the total current consumption of the load 3 to be controlled in the total power consumption and / or the total current consumption.

Next, a process in which the specifying unit 22 specifies the threshold overtime period will be described. For example, the specifying unit 22 can specify the power consumption or current consumption of each load 3 to be controlled based on the control target load information illustrated in FIG. 4 held by the power management apparatus 1. Further, the specifying unit 22 is based on the first operation schedule (see FIG. 7) of each of the controlled loads 3 generated by the provisional determining unit 21. The band can be specified.

For example, the specifying unit 22 divides the day for each time zone in which the combinations of the loads 3 to be controlled are matched, based on the first operation schedule. And the specific | specification part 22 calculates the sum total of the power consumption or current consumption in each time slot | zone by adding the power consumption or current consumption of the load 3 of the control object which is operating for every divided time slot | zone. Thereafter, the specifying unit 22 compares the calculated total with a predetermined threshold value, and specifies a time zone in which the total exceeds the predetermined threshold value as a threshold overtime zone.

When the identifying unit 22 identifies the threshold overtime period, the identifying unit 22 inputs information indicating the identified threshold overtime period to the extracting unit 23. The specifying unit 22 further includes information to be divided for each time zone in which the combination of the load 3 to be controlled operating in the threshold overtime zone matches, and the total calculated in each time zone and a predetermined value. Information indicating a difference (over value) from the threshold value may be input to the correction unit 24.

Referring back to FIG. 12, the extraction unit 23 extracts the load 3 whose schedule can be adjusted from the loads 3 to be controlled that are scheduled to operate in the threshold overtime period in the first operation schedule.

For example, the extraction unit 23 may extract the load 3 to be controlled whose rate indicated by the operation rate information (see FIG. 5) is not 100% as the load 3 whose schedule can be adjusted. In addition, the extraction unit 23 extracts the load 3 to be controlled that is longer than the time indicated by the operation time information (see FIG. 5) as the load 3 whose schedule can be adjusted. May be.

In such a load 3 to be controlled, among the candidate time zones to be operated, there is a time zone that is not the operating time in the first operating schedule. For this reason, a part or all of the time zone which is the operation time in the first operation schedule can be moved to another time zone among the candidate time zones to be operated. The extraction unit 23 extracts, for example, such a load 3 to be controlled as a load 3 whose schedule can be adjusted.

In addition, the extraction unit 23 may extract the load 3 to be controlled whose rate indicated by the operation rate information (see FIG. 5) is equal to or less than a predetermined value as the load 3 whose schedule can be adjusted. In addition, the extraction unit 23 determines the load 3 to be controlled whose total time of the time zone candidates to be operated is longer than the time indicated by the operation time information (see FIG. 5) and whose difference is equal to or greater than a predetermined value. You may extract as the load 3 which can adjust a schedule.

In such a load 3 to be controlled, there are enough time zones that are not in operation time in the first operation schedule among the time zone candidates to be operated. For this reason, it is easy to move the time zone which is the operation time in the first operation schedule to another time zone among the candidate time zones to be operated.

The extraction unit 23 divides the threshold overtime period into predetermined unit time periods (for example, a time period of 15 minutes, a time period of 30 minutes, a time period of 1 hour), and for each unit time period, The control target load 3 capable of adjusting the schedule is extracted. For example, the extraction unit 23 divides the threshold overtime period into time periods in which the combinations of operating control target loads 3 match, and the control target load 3 whose schedule can be adjusted for each time period. May be extracted. The extraction unit 23 inputs the extraction result (information indicating the time zone and the load 3 to be controlled whose schedule can be adjusted in the time zone) to the correction unit 24.

Returning to FIG. 12, the correction unit 24 corrects one or more first operation schedules in the load 3 to be controlled extracted by the extraction unit 23. Specifically, the correction unit 24 corrects the first operation schedule of the load 3 to be corrected so that the operation time in the threshold overtime period is reduced.

The correction unit 24 divides the threshold overtime period into predetermined unit time periods (for example, a time period of 15 minutes, a time period of 30 minutes, a time period of 1 hour), and The first operation schedule is corrected. For example, the correction unit 24 divides the threshold overtime period for each time period in which the combination of the loads 3 to be controlled that coincide with each other, and corrects the first operation schedule for each time period.

First, the correction unit 24 divides the threshold overtime period into time periods in which the combinations of the controlled loads 3 that are in operation match based on the information input from the specifying unit 22. Thereafter, the correction unit 24 sets one time zone as a processing target, and based on the information input from the specifying unit 22, the over value (total power consumption or total current consumption of the load 3 to be controlled) in the time zone. And a predetermined threshold).

Next, the correction unit 24 specifies the load 3 to be controlled that can adjust the schedule in the time zone based on the information input from the extraction unit 23. Thereafter, the correction unit 24 identifies the load 3 for correcting the first operation schedule from among the loads 3 to be controlled that can be adjusted in the time period. Although the specific method is not particularly limited, for example, it may be specified such that the total power consumption of the specified load 3 exceeds the over value in order from the larger or smaller power consumption.

Thereafter, the correction unit 24 corrects the first operation schedule of the identified load 3 by the following processing.

・ Correct so that it does not operate during the time zone.
-Ensure operation for the processing target time in other time zones among the candidates to be operated. At this time, it secures from the threshold time overtime zone and the time zone excluding the time that has already been operated in the first operation schedule.

In this way, when the correction unit 24 corrects the first operation schedule of the specified load 3, at least a part of the operation scheduled in the threshold overtime period is included in other time period candidates to be operated. You can move in the time zone.

When a first operation schedule that does not have a threshold overtime period is generated by such correction processing, the first operation schedule after the correction processing becomes the operation schedule of each load 3 to be controlled. As a result, as shown in FIG. 8, an operation schedule for each load 3 to be controlled is obtained.

In addition, when the acquisition part 10 has acquired continuous operation time information (refer FIG. 5), the determination part 20 produces | generates and corrects a 1st operation schedule based on the said continuous operation time information. That is, the acquisition unit 10 generates and corrects the first operation schedule so that the continuous operation time does not become less than the continuous use time.

Next, an example of the flow of processing by the power management apparatus 1 of this embodiment will be described using the flowchart of FIG.

First, the acquisition unit 10 acquires candidate time zone information indicating candidate time zones to be operated corresponding to each of the plurality of loads 3 to be controlled (S10). The acquisition unit 10 further corresponds to each of the plurality of loads 3 to be controlled, operation ratio information indicating the ratio of the operation time to the total time of the time zone candidates to be operated, a predetermined unit period (eg, one day) It is also possible to acquire at least one of operating time information indicating the time to operate and continuous operating time information indicating the time to operate continuously.

Thereafter, the provisional determination unit 21 generates a first operation schedule for operating the load 3 for some or all of the time zone candidates to be operated for each load 3 to be controlled (S11).

Thereafter, the specifying unit 22 is a time zone (threshold overtime) in which the total power consumption or current consumption of the plurality of loads 3 to be controlled exceeds a predetermined threshold in the case of following the first operation schedule generated in S11. Obi).

If there is no threshold overtime zone (No in S12), the first operation schedule determined in S11 is determined as the operation schedule of each load 3 to be controlled (S15).

On the other hand, when there is a threshold overtime zone (Yes in S12), the extraction unit 23 extracts a load whose schedule can be adjusted from the loads 3 scheduled to operate in the threshold overtime zone (S13). ).

Then, the correction unit 24 corrects any one or more first operation schedules in the load 3 extracted in S13 so that the operation time in the threshold overtime period is reduced (S14). The correcting unit 24 corrects one or more first operation schedules in the load 3 extracted in S13 so that the threshold overtime period does not exist.

And the 1st operation schedule corrected by S14 is determined as an operation schedule of each load 3 to be controlled (S15).

As described above, according to the power management apparatus 1 of the present embodiment described above, there is no threshold overtime zone in which the total power consumption or current consumption of the plurality of loads 3 to be controlled exceeds a predetermined threshold by the processing by the computer. In addition, it is possible to generate operation schedules for a plurality of loads 3 to be controlled.

In addition, the power management apparatus 1 according to the present embodiment is configured so that the total of these power consumptions does not exceed a predetermined threshold for at least some of the operation schedules among a plurality of loads used within a predetermined power consumption unit. Can be generated. Some of the loads are used relatively regularly. The power management apparatus according to the present embodiment can create an operation schedule for such a load so that the total power consumption of such a load does not exceed a predetermined value. That is, the total power consumption of such loads is leveled. This is expected to suppress inconvenience that the total power consumption within a predetermined power consumption unit exceeds a predetermined value.

In addition, the power management apparatus 1 according to the present embodiment has at least one of candidate time zone information, operation ratio information, operation time information, and continuous operation time information specified by the user, or actual usage results of each load 3. Based on these pieces of information specified by the analysis, it is possible to generate operation schedules for a plurality of loads 3 to be controlled. For example, it is possible to generate an operation schedule that is determined to operate in a candidate time zone for operation specified by these pieces of information. Further, it is possible to generate an operation schedule that is determined to operate for the time specified by these pieces of information. In addition, it is possible to generate an operation schedule in which the continuous time specified by these pieces of information is secured. For this reason, it is possible to suppress the inconvenience of generating an operation schedule that is far from the user's wishes.

<Second Embodiment>
In the present embodiment, in the candidate time zone information indicating candidates for the time zone in which the load 3 to be controlled is operated, the candidate time zone is the first time zone that is necessarily operated and the second time that may be operated. Can be divided into bands. And a 1st operation schedule is produced | generated and corrected based on such candidate time slot | zone information, and an operation schedule can be produced | generated. Details will be described below.

An example of a functional block diagram of the power management apparatus 1 of the present embodiment is shown in FIG. 12 as in the first embodiment.

The acquisition unit 10 acquires information as shown in FIG. As shown in FIG. 10, the candidate time zone information acquired by the acquisition unit 10 of the present embodiment is divided into a first time zone that is necessarily operated and a second time zone that may be operated.

For example, the user determines a time zone (first time zone) in which each load 3 is necessarily operated and a time zone (second time zone) in which the load 3 may be operated, and inputs the time zone to the power management apparatus 1. be able to. And the acquisition part 10 can acquire the input information.

Alternatively, the power management apparatus 1, the server 4, or the monitoring apparatus 6 can analyze past usage records of each of the loads 3 to be controlled and generate such information.

For example, the power management apparatus 1, the server 4, or the monitoring apparatus 6 analyzes past usage records and operates at a predetermined probability (eg, 5 days / 10 days or more and less than 8 days / 10 days). A time zone may be specified. And the said time slot | zone is good also as a 2nd time slot | zone.

Further, the power management apparatus 1, the server 4 or the monitoring apparatus 6 may analyze past usage records and specify a time zone in which the power management apparatus 1, the server 4 or the monitoring apparatus 6 is operating with a predetermined probability (eg, 8 days / 10 days or more). And the said time slot | zone is good also as a 1st time slot | zone. The predetermined probability in specifying the first time zone is greater than the predetermined probability in specifying the second time zone.

In addition, since the other structure by the acquisition part 10 is the same as that of 1st Embodiment, description here is abbreviate | omitted.

That is, the provisional determination unit 21 designates the operation time for the time specified by the operation ratio information or the operation time information in the candidate time zone specified by the candidate time zone information, and sets the first operation schedule. Is generated. In addition, when the time slot | zone designated as the 1st time slot | zone exists in the candidate of the time slot | zone to operate | move, the temporary determination part 21 makes the 1st operation schedule always operate | moved in a 1st time slot | zone. Generate.

The load 3 to be controlled with the load ID “00001” has a duration of 7 hours on the day. The time zone candidates to be operated are from 5 o'clock to 10 o'clock and from 19 o'clock to 24 o'clock, of which 6 o'clock to 9 o'clock and 20 o'clock to 22 o'clock are designated as the first time zone. .

In this case, the tentative determination unit 21 designates the operating time from 6:00 to 9:00 and from 20:00 to 22:00. Then, from the remaining candidates, a time zone for operating for 2 hours is designated.

Other configurations by the provisional determination unit 21 are the same as those in the first embodiment, and thus description thereof is omitted here.

Since the configuration of the specifying unit 22 is the same as that of the first embodiment, a description thereof is omitted here.

The extraction unit 23 extracts the load 3 to be controlled that is scheduled to operate during the threshold overtime period and the second time period as the load 3 that can be adjusted in schedule. Since the other structure by the extraction part 23 is the same as that of 1st Embodiment, description here is abbreviate | omitted.

Since the configuration of the correction unit 24 is the same as that of the first embodiment, a description thereof is omitted here.

According to the present embodiment described above, the same operational effects as those of the first embodiment can be realized.

Further, according to the present embodiment, the time zone candidates for operating the load 3 to be controlled can be divided into the first time zone that is always operated and the second time zone that may be operated. Then, an operation schedule that is scheduled to operate in the first operation time zone can be generated. According to this embodiment, it is possible to generate an operation schedule that is well suited to the user's needs.

<Third Embodiment>
The power management apparatus 1 according to the present embodiment has a function of controlling the operation of the load 3 to be controlled based on the generated operation schedule.

FIG. 11 shows an example of a functional block diagram of the power management apparatus 1 of the present embodiment. As illustrated, the power management apparatus 1 includes an acquisition unit 10, a determination unit 20, and a load control unit 30. The configurations of the acquisition unit 10 and the determination unit 20 are the same as those in the first and second embodiments.

The load control unit 30 controls the operation state of each of the plurality of loads 3 to be controlled using the first operation schedule in which the threshold overtime period does not exist as an operation schedule. That is, the load control unit 30 performs an operation start instruction input and an operation stop instruction input to each load 3 to be controlled so as to operate according to the operation schedule based on the operation schedule. The instruction input is realized via a wired and / or wireless communication network that exists between the power management apparatus 1 and the load 3 to be controlled.

According to the present embodiment described above, the same operational effects as those of the first and second embodiments can be realized.

Further, according to the present embodiment, according to the operation schedule of each of the plurality of loads 3 generated so that the total power consumption or current consumption of the plurality of loads 3 to be controlled does not exceed a predetermined threshold, The load 3 can be operated. For this reason, the inconvenience that the sum of the power consumption or current consumption of the plurality of loads 3 to be controlled exceeds the predetermined threshold can be suppressed.

<Fourth Embodiment>
FIG. 3 shows an example of a functional block diagram of the power management apparatus 1 of the present embodiment. As illustrated, the power management apparatus 1 includes an acquisition unit 10 and a determination unit 20. The determining unit 20 includes a temporary determining unit 21 and a specifying unit 22. The configurations of the acquisition unit 10, the provisional determination unit 21, and the specification unit 22 are the same as those in the first to third embodiments.

According to the present embodiment, after the first operation schedule is created for each load 3, the total power consumption or current consumption of the plurality of loads 3 exceeds a predetermined threshold when the first operation schedule is followed. It is possible to specify a threshold overtime zone that is a time zone. That is, according to the present embodiment, it is possible to detect the inconvenience that the total exceeds the predetermined threshold in the first operation schedule. For this reason, it is possible to take a predetermined measure for improving such inconvenience according to the detection. When the threshold overtime period cannot be specified in the first operation schedule, the first operation schedule can be used as the operation schedule for the load 3 as it is.

<Fifth Embodiment>
An example of a functional block diagram of the power management apparatus 1 of the present embodiment is shown in FIGS. 3, 11, and 12 as in the first to fourth embodiments.

Similar to the first to fourth embodiments, the specifying unit 22 is a threshold overtime period in which the total power consumption or current consumption of the plurality of loads 3 exceeds a predetermined threshold when the first operation schedule is followed. Is identified.

In the present embodiment, the predetermined threshold is the maximum power and / or maximum current that can be supplied from the commercial power source to the unit power network 100, the total power consumption and / or the total current consumption of the load 3 connected to the unit power network 100. It is arbitrarily determined based on the total power consumption and / or the ratio of the total current consumption of the load 3. That is, in determining the predetermined threshold, the maximum power and / or maximum current that can be supplied from the power storage system 2 to the unit power network 100 is not considered.

As in the first to fourth embodiments, the correction unit 24 sets any one or more first operation schedules in the load 3 extracted by the extraction unit 23 to less operation time in the threshold overtime period. Modify to be.

In the present embodiment, the correction unit 24 corrects the threshold overtime period without considering the first threshold overtime period in which the output from the power storage system 2 is considered and the output from the power storage system 2. It classify | categorizes into the 2nd threshold value over time slot | zone. For example, when the correction unit 24 acquires information indicating the threshold overtime period specified by the specification unit 22, the correction unit 24 generates an operation schedule of the power storage system 2 that operates in at least a part of the threshold overtime period. The time zone for operating the power storage system 2 in the threshold overtime zone is the first threshold overtime zone. The time zone during which the power storage system 2 in the threshold overtime zone is not operated is the second threshold overtime zone. The method of classifying the threshold overtime zone into the first and second threshold overtime zones is not particularly limited, and various methods can be adopted.

In the second threshold overtime period, the correction unit 24 includes the load 3 extracted by the extraction unit 23 so that the total power consumption or current consumption of the plurality of loads 3 is equal to or less than a predetermined value M. Any one or more of the first operation schedules is modified.

On the other hand, in the first threshold overtime period, the correction unit 24 loads the load 3 extracted by the extraction unit 23 so that the total power consumption or current consumption of the plurality of loads 3 is equal to or less than a predetermined value (M + X). Modify one or more of the first operation schedules.

M is a positive value, and may be, for example, the same value as a predetermined threshold used by the specifying unit 22 to specify the threshold overtime period. X is a positive value and is determined in consideration of the output from the power storage system 2. In the first threshold overtime period, the output X from the power storage system 2 is taken into consideration, and the corrected threshold value of the total power consumption or current consumption of the plurality of loads 3 is larger than that in the second threshold overtime period. It has become.

Other configurations of the present embodiment are the same as those of the first to fourth embodiments. According to the present embodiment described above, the same operational effects as those of the first to fourth embodiments can be realized. Moreover, according to this embodiment, the operation schedule of the load 3 can be determined in consideration of the time zone during which the power storage system 2 is operated and the time zone during which the power storage system 2 is not operated. As a result, it is possible to generate an operation schedule of a beneficial load 3 in accordance with the operation state of the power storage system 2.

<Sixth Embodiment>
In the present embodiment, an arbitrary control device controls the operation of the power storage system 2 based on the operation schedule of the load 3 generated in the first to fifth embodiments. The control device may be the load control unit 30, the server 4, or the monitoring device 6 of the power management device 1 shown in FIG. The power storage system may have a control device that controls the operation of the system. Further, another device not shown in FIG. 2 may be the control device. The other device can communicate with the power storage system 2 by wire and / or wireless, and controls the power storage system 2.

Based on the operation schedule, the control device specifies a timing (eg, a timing when the power is turned on, a timing when the power is applied) at which the power consumption of the predetermined load 3 exceeds a predetermined threshold before the timing. . Then, power supply from the power storage system 2 to the unit power network 100 is started a predetermined time before the timing.

Consumption from the commercial power source at the timing when the power consumption of the predetermined load 3 (the load 3 whose power consumption is equal to or greater than the predetermined value) exceeds a predetermined threshold (eg, when the power is turned on, when the power is applied) The power tends to exceed a predetermined threshold. Thus, if power supply from the power storage system 2 is started at this timing, it is considered that the inconvenience that the power consumption from the commercial power source exceeds a predetermined threshold can be reduced. However, for example, if the power supply from the power storage system 2 is started at the same time as the power is turned on, there may be a problem that the power consumption from the commercial power supply temporarily exceeds a predetermined threshold. . Details will be described below.

First, let t1 be the time from the timing when the power source of the predetermined load 3 is turned on to the timing when the power consumption of the predetermined load 3 becomes a predetermined value (w1). In this case, the power consumption increase rate (V1) of the predetermined load from when the power is turned on until the power consumption reaches a predetermined value (w1) is represented by w1 / t1.

Meanwhile, let t2 be the time from the timing when the power supply of the power storage system is started to the timing when the output power reaches a predetermined value (w1). In this case, the output power increase rate (V2) of the power storage system from when the power supply is started until the output power reaches a predetermined value (w1) is represented by w1 / t2.

Some of the predetermined loads 3 satisfy V2 <V1. In this case, if the power supply from the power storage system 2 is started at the timing when the predetermined load 3 is turned on, the power supply from the power storage system 2 is not in time, and the total power consumption from the commercial power supply is temporarily However, there are cases where a predetermined threshold is exceeded.

In order to alleviate the inconvenience, in the present embodiment, based on the operation schedule, the timing at which the power consumption of a predetermined load 3 (eg, load 3 whose power consumption is equal to or greater than a predetermined value) exceeds a predetermined threshold (eg, the power source is The power supply from the power storage system 2 is started a predetermined time before the timing of turning on and the timing of applying power. As a result, the above disadvantages are reduced.
