Abstract

A consumer power management system (12) to which is transmitted a small-scale power-saving command amount (q1), a large-scale power-saving command amount (B1), and a large-scale actual power-saving amount (B2) obtained by combining the small-scale actual power-saving amounts (b2) of the consumer power management systems (12) subordinate to an aggregator system (10). The consumer power management system (12) determines its own small-scale actual power-saving amount (b2) on the basis of the power consumption of electrical devices (56) subordinate thereto, and determines an additional small-scale power-saving command amount (b01) on the basis of the difference between the large-scale power-saving command amount (B1) and the large-scale actual power-saving amount (B2). When its own small-scale actual power-saving amount (b2) is equal to or greater than a small-scale power-saving command amount (b1) the consumer power management system (12) calculates a fixed power-saving command amount (q1) with respect to the electrical devices (56) subordinate thereto on the basis of the additional small-scale power-saving command amount (b01).

Description

Power demand control system, power demand control method, aggregator system, consumer power management system, and program

The present invention relates to a power demand control system, a power demand control method, an aggregator system, a consumer power management system, and a program for controlling power demand through so-called demand response (DR).

In recent years, the ratio of the amount of power generated by renewable energy, such as solar power generation and wind power generation, to the total amount of power generated by electric utilities has increased. Since the amount of power generated by renewable energy increases and decreases depending on the weather (sunlight, air volume, etc.), a system for adjusting the supply and demand balance of electric power that can cope with such fluctuations is required.

For example, in recent years, a power supply / demand adjustment called demand response (DR) is known in which a consumer side that consumes power temporarily controls received power (purchased power) in accordance with fluctuations in the amount of power generated by an electric power company. ing.

Furthermore, regarding this demand response, an operator called an aggregator that adjusts power supply and demand by entering between an electric company and a plurality of consumers is known. When the aggregator receives, for example, a request for reducing the amount of electric power (large power saving command amount) from an electric power company, the aggregator distributes the request to a small power saving command amount for a subordinate (contractor) consumer. The consumer is given an incentive such as a reduction in electric power charges, for example, from an electric power company according to the actual power saving performance (the actual amount of small power saving) according to the allocated small power saving command amount. Further, for example, a predetermined reward is paid from the electric power company to the aggregator in accordance with the overall success rate (of all consumers) of demand response (large amount of power saving actual amount / large amount of power saving command amount).

The aggregator allocates the large power saving command amount received from the electric power company to the small power saving command amount based on the surplus power (capable power saving amount, DR possible amount) of each consumer acquired in advance. However, in reality, in the process of demand response, there is not enough capacity for the power saving amount initially set for the consumer, and it is difficult to save power that satisfies the small power saving command amount, or vice versa. There may be more reserve capacity than the amount that can be saved.

Therefore, for example, in Patent Documents 1 and 2, the power saving command amount is redistributed according to the actual amount of power saving of each consumer. For example, an aggregator (a power consumption management device or an energy management system) monitors a small amount of power saving actual amount (DR actual amount) of each consumer periodically during a demand response execution period. During the monitoring process, a small amount of power saving command amount is deducted by a predetermined amount for a customer who is difficult to achieve the amount of power saving command amount. On the other hand, for customers who have achieved a small power-saving command amount and still have spare capacity, the amount subtracted above is turned. Through such redistribution, the power saving command amount to be sent to each consumer is adjusted as appropriate to achieve the power saving target for all consumers.

Japanese Patent Laid-Open No. 2015-116038 JP 2012-165513 A

By the way, the redistribution process of the power saving command amount is transmitted from the consumer to the aggregator, and the aggregator receives it, and then obtains the difference between the power saving command amount and the power saving command amount. The process of correcting (redistributing) the power saving command amount and transmitting it to each consumer from the aggregator is followed. When there are a plurality of consumers (for example, about 100) under the control of an aggregator, an interval is provided for communication between each consumer and the aggregator in order to reduce the communication load. That is, after a small amount of actual power saving is transmitted from a predetermined consumer to the aggregator, a corrected small power saving command amount is transmitted from the aggregator via a predetermined interval. Due to such a delay due to the communication interval, there is a possibility that the redistribution of the small power saving command amount will be delayed, and for example, the redistribution of the small power saving command amount at the end of the demand response may not be in time. Therefore, an object of the present invention is to provide a power demand control system, a power demand control method, an aggregator system, a consumer power management system, and a program capable of redistributing small power saving command amounts more quickly than in the past.

<Overall configuration>
FIG. 1 illustrates a power system diagram including a power demand control system according to the present embodiment. The power demand control system according to the present embodiment includes an aggregator system 10 and a consumer power management system 12. In addition, in order to simplify illustration in FIG. 1, although only two persons, consumer

power management system

12A, 12B, are shown, it is not restricted to this form. For example, the aggregator system 10 has several tens to several hundred customer power management systems 12 under its control (distribution destination, contract destination).

The aggregator system 10 enters between an electric power company 14 such as an electric power company and a plurality of consumers, and adjusts a power saving command amount (DR command amount). The aggregator system 10 aggregates consumers, and uses a large power saving command amount B1 (large DR command amount) received from the electric utility 14 for a small power saving command amount b1 (small DR command amount) corresponding to each consumer. To distribute.

As will be described later, the aggregator system 10 includes a large power saving command amount B1 (a large DR command amount) sent from the electric utility 14 in addition to the small power saving command amount b1, and a large power saving actual amount that is an actual power saving amount. B2 is transmitted to each consumer power management system 12. The large power saving performance amount B2 is obtained by adding together the power saving performance amounts (small power saving performance amount b2) in the plurality of customer power management systems 12 under control (contractee).

The consumer power management system 12 is provided in each consumer such as a building and is subordinate to the consumer power management system 12 according to the small power saving command amount b1 (small DR command amount) distributed from the aggregator system 10 ( The power management of the electrical device 56 in the control target) is performed.

As will be described later, the consumer power management system 12 adds based on the difference between the large power saving command amount B1 (large DR command amount) and the large power saving performance amount B2 (large DR actual amount) transmitted from the aggregator system 10. The forefront power saving command amount b01 (additional forehead DR command amount) is calculated. In addition, the customer power management system 12 determines whether or not the actual power saving command amount b2 reaches the power saving command amount b1 as the progress of power saving when the actual power saving command amount b2 is equal to or greater than the power saving command amount b1 given to itself. Is exceeded, the determined power saving command amount q1 (fixed DR command amount) for the subordinate electric equipment is determined based on the additional small power saving command amount b01 in addition to the small power saving command amount b1.

In this manner, the consumer power management system 12 waits for redistribution from the aggregator system 10 by autonomously capturing the unachieved amount of the large power saving performance amount B2 with respect to the large power saving command amount B1 in its own small power saving command amount. Without this, quick redistribution is possible.

<Details of Aggregator System>
The aggregator system 10 enables information communication regarding demand response between the electric power company 14 and each consumer power management system 12. For example, the aggregator system 10 complies with OpenADR, which is a demand response protocol, and can communicate with the electric utility 14 and each consumer power management system 12 via a network such as the Internet.

The aggregator system 10 is provided, for example, by an energy usage information management operator. That is, the aggregator system 10 is a high-order system that bundles systems such as BEMS (Building and Energy Management System), which are monitoring and control systems for building facilities such as buildings, and these are spread over a plurality of building facilities, that is, a plurality of BEMS. The aggregator system 10 is provided in a company or the like that provides an energy support service that is centrally managed.

The management target of the aggregator system 10 is not limited to BEMS. For example, HEMS (Home Energy Management System), which is an energy monitoring system in the home, FEMS (Factor Energy Management System), which is an energy monitoring system in the factory, and CEMS (Cluster / CommunityEmergency, which is an energy management system in the region) ) Can also be managed by the aggregator system 10.

The aggregator system 10 is composed of, for example, a computer system (computer). As illustrated in the hardware configuration diagram of FIG. 1, the aggregator system 10 includes a CPU 16 (Central Processing Unit), a memory 18, a hard disk drive 20 (HDD), an input unit 22, an output unit 24, and an input / output interface 26. These devices are connected to each other via a system bus.

The input unit 22 includes input means such as a mouse and a keyboard. The output unit 24 includes a display device such as a display and a printing device such as a printer. The hard disk drive 20 is a computer-readable non-transitory storage medium that stores a program for executing a power saving amount distribution flow to be described later. When the program is executed by the CPU 16, the computer configuring the aggregator system 10 functions as each functional unit illustrated in FIG. The program may be stored in a storage medium including an optical disk such as a CD (Compact Disc) or a DVD (Digital Versatile Disc) and read by the CPU 16 or stored in the hard disk drive 20.

As shown in FIG. 2, the functional units of the aggregator system 10 include data transmission / reception units 28 </ b> A and 28 </ b> B, a performance collection unit 30, a performance database 32, a distribution policy database 34, and a small power saving command amount distribution unit 36. The These functional units are illustrated independently of each other for convenience or for convenience of explanation. For example, the functions of the CPU 16, the memory 18, and the hard disk drive 20 are appropriately allocated to configure each functional unit.

The data transmission / reception unit 28A is an interface for performing data transmission / reception with the electric utility 14. The data transmission / reception unit 28A acquires a large power saving command amount B1 (a large DR command amount), a demand response start time Ts, and a demand response end time Te from the electric utility 14. The large power saving command amount B1 may be set for every so-called demand time period (for example, 30 minutes). In addition, the data transmitting / receiving unit 28A transmits a large power saving actual amount B2 (large DR actual amount) to the electric utility 14.

The data transmission / reception unit 28B is an interface for performing data transmission / reception with the consumer power management system 12. The data transmitter / receiver 28B obtains a small amount of power saving actual amount b2 (small amount DR actual amount) from each consumer

power management system

12, 12,. Further, for each consumer

power management system

12, 12,..., Large power saving command amount B1 (large DR command amount), large power saving performance amount B2 (large DR actual amount), demand response start time Ts, demand response. The end time Te, the small power saving command amount b1 (the small DR command amount), and the number N1 of additionally allocable customers indicating the number of customers that can be additionally allocated are transmitted. The contents of each data will be described later.

The performance collecting unit 30 collects the power saving performance of the consumer power management system 12 and obtains the large power saving performance. The actual result collecting unit 30 acquires the small power saving actual amount b2 (the small DR actual amount) from, for example, all the customer

power management systems

12, 12, ... subordinate to the aggregator system 10 from the data transmitting / receiving unit 28B. Further, not only the power saving amount but also the actual power consumption may be acquired. In order to reduce the communication load, the consumer

power management systems

12, 12,... May sequentially transmit the small power saving actual amount b2 to the actual result collecting unit 30 at predetermined intervals. The performance collecting unit 30 calculates, for example, the sum of all the small power saving performance amounts b2 under the control of the aggregator system 10, and sets this as the large power saving performance amount B2.

Further, the performance collecting unit 30 compares the small power saving command amount b1 distributed by the small power saving command amount distribution unit 36 to each consumer power management system 12 and the small power saving actual amount b2 acquired from each consumer power management system 12. Thus, the actual power saving amount b2 is equal to or greater than the small power saving command amount b1, that is, the number of customer power management systems 12 that have saved power more than the command amount is obtained, and this can be additionally allocated N1 ( Number of additional allocations). The obtained additional allocatable demand number N1 is transmitted to each consumer power management system 12. As will be described later, the additionally allocable number is used as a parameter for obtaining allocation to itself when each consumer power management system 12 autonomously captures the unreached portion of the large power saving command amount B1.

The actual result database 32 acquires the small power saving actual result amount b2 of each customer power management system 12 from the actual result collecting unit 30. At the same time, large-scale power-saving command amount B1, small-scale power-saving command amount b1, number N1 of additional allocable consumers, power consumption of each consumer power management system, etc., power-saving success rate (= power-saving actual amount / power-saving command amount) May be acquired and stored. These data may be stored in synchronization with the acquired date.

The distribution policy database 34 stores an allocation policy 102 that serves as a reference when allocating the large power saving command amount B1 to the small power saving command amount b1. The distribution policy 102 is a standard for determining the power saving possible amount q3 (remaining power, DR possible amount) of each consumer, and various distribution ratios are set based on, for example, the weather and the temperature. The distribution policy 102 is determined at the time of contract between the aggregator system 10 and the consumer power management system 12, for example.

The small power saving command amount distribution unit 36 distributes the large power saving command amount B1 to the small power saving command amount b1 for each consumer power management system 12. The small power saving command amount distribution unit 36 stores the power saving results (for example, success rate) of each customer power management system 12 stored in the result database 32 and the distribution of each customer power management system 12 stored in the distribution policy database 34. Based on the policy 102, the distribution process of the small power saving command amount b1 proceeds. For example, the small power saving command amount b1 is obtained so that the average value of the success rate of each consumer power management system 12 is 100% or more and the total of the small power saving command amount b1 is equal to or larger than the large power saving command amount B1. As will be described later, the power saving command amount b1 may be set every so-called demand time period (for example, 30 minutes).

<Details of customer power management system>
In FIG. 1, the consumer power management system 12 is configured to include an energy management system such as the above-described BEMS, HEMS, FEMS, CEMS, or the like. In FIG. 1, BEMS is cited as an example of the consumer power management system 12.

The customer power management system 12 includes a central device 48, a sub-controller 50, a digital controller 52, a remote station 54, and a sensor 58, and controls various electrical devices 56. The electrical equipment 56 is various equipment installed in the building, and includes, for example, air conditioning equipment, lighting equipment, sanitary equipment, disaster prevention equipment, crime prevention equipment, and power equipment.

The central device 48 is composed of, for example, a so-called B-OWS (BACnet Operator Workstation), and has a function as a client PC that is monitored and operated by a monitoring staff and a server that performs data storage and application processing. ing. In the central device 48, for example, screen display and setting operations are performed.

The sub-controller 50 is mainly responsible for the control function. The sub-controller 50 is configured by, for example, a so-called B-BC (Building Controller), and communicates with terminal transmission devices such as the digital controller 52 and the remote station 54 to manage point data, schedule control, and the like. For example, one sub-controller 50 is provided for each function-specific system (sub-system) such as an air-conditioning equipment system, a lighting equipment system, a sanitary equipment system, and a security equipment system.

The central device 48 and the sub-controller 50 constitute a host system of the consumer power management system 12. In this host system, a plurality of facility devices are controlled in an integrated manner. For example, it has functions such as start / stop control based on the air conditioning schedule.

The digital controller 52 may be a so-called DDC (Direct Digital Controller), and has a function as a regulator for realizing distributed control in BEMS. For example, the digital controller 52 controls the connection-destination electric device 56 by program control based on timer settings sent from the sub-controller 50, feedback control based on target values sent from the sub-controller 50, or the like. Further, the digital controller 52 transmits the measurement value of the sensor 58, the warning of the electric device 56, and the like to the system and other digital controllers 52.

The remote station 54 is also called an out-station or a local station, and monitors and controls the connection destination sensor 58 and the electric device 56. Functionally, the digital controller 52 and the remote station 54 are appropriately selected depending on the electrical device 56 and the sensor 58 to be connected.

The central device 48, the sub controller 50, the digital controller 52, and the remote station 54 are composed of computers. For example, as shown in FIG. 3, a CPU 60, a memory 62, a hard disk drive 64, an input unit 66, an output unit 68, and an input / output interface 70 are provided in all of them.

For example, the consumer power management system 12 adopts a so-called vertical distributed control system. For example, the air conditioning schedule created by the central device 48 is stored in the digital controller 52 or the hard disk drive 64 of the remote station 54 via the sub-controller 50. By doing in this way, even if the host system (the central device 48 and the sub-controller 50) goes down, it becomes possible to control each electrical device by the host system (the digital controller 52, the remote station 54, and the sensor 58).

FIG. 4 illustrates functional blocks of the central device 48. The central device 48 includes a data transmission / reception unit 72, a data collection unit 74, a performance database 76, a baseline calculation unit 78, a small power saving performance amount calculation unit 80, an addition /

subtraction unit

82A, 82B, a small power saving adjustment unit 84, and a large power saving adjustment unit 86. The adjustment amount output unit 88 and the equipment control unit 90 are included. Among the above functional units, the addition /

subtraction units

82A and 82B, the small power saving adjusting unit 84, the large power saving adjusting unit 86, and the adjustment amount output unit 88 constitute a power saving amount adjusting unit 92, which will be described later. In this way, it is possible to redistribute the power saving amount autonomously.

In FIG. 4, the functional units are illustrated independently of each other for the sake of convenience or for ease of understanding. For example, the CPU 60 executes a power saving amount distribution program stored in a hard disk drive 64 that is a computer-readable storage medium or an optical disk such as a CD or a DVD, so that resources of the CPU 60, the memory 62, and the hard disk drive 64 are appropriately set. Assigned to each functional unit.

The data transmitter / receiver 72 receives various data from the aggregator system 10. Specifically, the data transmitter / receiver 72 aggregates the small power saving command amount b1, the large power saving command amount B1, the large power saving performance amount B2, the demand response start time Ts, the demand response end time Te, and the number N1 of additional allocable customers. Receive from system 10. In addition, the data transmitting / receiving unit 72 transmits the actual power saving amount b <b> 2 to the aggregator system 10.

The data collection unit 74 acquires the actual amount of power consumption from the power sensor among the sensors 58 (instrument group). The actual amount may be a unit of sensor 58 or may be a unit of equipment. The data collection unit 74 obtains the sum of the actual amounts of power consumption and sets this as the actual power consumption amount Q2 of the entire consumer power management system (EMS unit).

The baseline calculation unit 78 calculates a baseline BL that is a reference for calculating a power saving performance amount. As illustrated in FIG. 5, the baseline BL indicates the power consumption assumed when a demand response is not requested, and the difference between the baseline BL and the actual power consumption Q2 is the actual power saving amount. Become.

Demand demand start time Ts and demand response end time Te are transmitted from the data transmission / reception unit 72 to the baseline calculation unit 78. In addition, the baseline calculation unit 78 acquires the past power consumption data 201 of the electric devices under the customer power management system 12 from the performance database 76.

In calculating the baseline BL, for example, the known High 4 of 5 may be used. That is, the baseline calculation unit 78 stores the past five days or more in the same period as the period from the demand response start time Ts to the end time (DR execution time period) excluding the demand response execution date. Get the power consumption of. Further, the baseline calculation unit 78 sequentially calculates an average value in units of 30 minutes of demand data for four days with a large average demand in the five-day DR execution time period, and sets this as the baseline BL.

The performance database 76 acquires the actual power consumption Q2 in EMS units from the data collection unit 74. Considering the calculation of the baseline BL described above, the performance database 76 may store the actual power consumption amount Q2 in EMS in synchronization with a clock function (not shown) in synchronization with the date and time. In addition, the actual power consumption amount q2 per sensor may be stored together with the actual power consumption amount Q2 per EMS.

The small power saving actual amount calculation unit 80 acquires the baseline BL from the baseline calculation unit 78, and acquires the actual power consumption amount Q2 in EMS units from the result database 76. Further, the actual power saving amount calculation unit 80 subtracts the actual power consumption amount Q2 in EMS units from the baseline BL, and sets this as the actual power saving amount b2. As described above, when the baseline BL is 30 minutes per frame, the power saving amount b2 may be calculated at a time interval shorter than 30 minutes in order to enable power saving amount adjustment in one frame. . For example, the actual power saving amount b2 may be calculated at intervals of 5 minutes.

The addition / subtraction unit 82A calculates a small power saving remaining amount b3 obtained by subtracting the small power saving actual amount b2 from the small power saving command amount b1. Similarly, the addition / subtraction unit 82B calculates a large power saving remaining amount B3 obtained by subtracting the large power saving actual amount B2 from the large power saving command amount B1.

The small power saving adjustment amount 84 is transmitted to the small power saving adjustment unit 84 from the addition / subtraction unit 82A, and the small power saving adjustment amount b4 is calculated based on this. The power saving adjustment amount b4 is, for example, a value obtained by multiplying the power saving remaining amount b3 by a predetermined gain, and is obtained by, for example, PID control.

A large power saving remaining amount B3 is transmitted from the adder / subtractor 82B to the large power saving adjusting unit 86. Further, the number N1 of customers who can be additionally allocated is transmitted from the data transmitting / receiving unit 72 to the large power saving adjusting unit 86. The large power saving adjusting unit 86 obtains, for example, a value multiplied by a predetermined gain based on the value divided by the large power saving remaining amount B3 and the number of additional allocable customers N1, and this is set as the additional small power saving command amount b01. . That is, the large power saving adjusting unit 86 obtains a value obtained by multiplying a predetermined gain, for example, based on a value obtained by dividing the large power saving remaining amount B3 by the number N1 of additional allocable consumers, and adds this to the additional small power saving command amount b01. And
In this example, the additional small power saving command amount b01 is obtained by multiplying the value obtained by dividing the large power saving remaining amount B3 by the number N1 of additional allocable customers by a predetermined gain.
Note that the number of all customer power management systems 12 under the aggregator system 10 may be used instead of the number of additional allocatable customers N1.

The adjustment amount output unit 88 acquires the small power saving adjustment amount b4 and the small power saving remaining amount b3 from the small power saving adjustment unit 84, and acquires the additional small power saving command amount b01 from the large power saving adjustment unit 86. The adjustment amount output unit 88 determines whether the small power saving remaining amount b3 is 0 or less. That is, it is determined whether or not the actual power saving amount b2 is greater than or equal to the power saving command amount b1.

When the small power saving remaining amount b3 exceeds 0, that is, when the small power saving performance amount b2 has not reached the small power saving command amount b1, the adjustment amount output unit 88 performs the small power saving from the viewpoint of giving priority to its own power saving. The adjustment amount b4 is transmitted to the equipment control unit 90 as the fixed power saving command amount q1.

On the other hand, when the small power saving remaining amount b3 is 0 or less, that is, when the small power saving performance amount b2 has reached the small power saving command amount b1, the adjustment amount is used to digest the unsatisfied amount of the large power saving amount. The output unit 88 obtains a fixed power saving command amount q1 based on the additional small power saving command amount b01 in addition to the small power saving adjustment amount b4 and transmits it to the equipment control unit 90. For example, the sum of the small power saving adjustment amount b4 and the additional small power saving command amount b01 is set as the fixed power saving command amount q1.

The facility control unit 90 performs power management of a device group (facility group 56) such as the air conditioner 56 and the lighting device 56 based on the determined power saving command amount q1. For example, the determined power saving command amount q1 is appropriately distributed to the subordinate devices, and the power saving operation is executed.

<Energy saving flow>
FIG. 6 illustrates a flow on the aggregator system 10 side in the power saving amount distribution flow according to the present embodiment. FIG. 7 illustrates a flow on the customer power management system 12 side in the power saving amount distribution flow according to the present embodiment.

This will be described with reference to FIG. The data transmitting / receiving unit 28A of the aggregator system 10 receives the large power saving command amount B1, the demand response start time Ts, and the demand response end time Te from the electric utility 14 (S10). This corresponds to the DR notice in FIG.

Next, as described above, the small power saving command amount allocation unit 36 performs the small power saving command amount for each consumer power management system 12 based on the large power saving command amount B1, the distribution policy 102, and the past performance data 101. b1 is allocated (S12). Further, the data transmission / reception unit 28B transmits a demand response start time Ts, a demand response end time Te, a large power saving command amount B1, and a small power saving command amount b1 to each consumer power management system (S14). Steps S10 to S14 are executed during the DR reaction time in FIG.

The aggregator system 10 determines whether or not the demand response start time Ts has been reached (S16), and if not reached, waits for a predetermined time (S18). When the demand response start time Ts is reached, the performance collecting unit 30 collects the small power saving actual amount b2 from each consumer power management system 12 (S20) and calculates the large power saving actual amount B2 (S22). Further, the result collecting unit 30 obtains the number N1 of additionally allocable customers (S24).

Next, the large power saving command amount B1, the small power saving command amount b1, the large power saving command amount B2, and the number N1 of additional allocable customers are transmitted to each consumer power management system 12 via the data transmitting / receiving unit 28B. (S26).

The aggregator system 10 determines whether or not the demand response end time Te has been reached (S28), and if not, returns to step S20. When the demand response end time Te is reached, this flow ends.

As illustrated in FIG. 7, the consumer power management system 12 receives the power saving command amount b1, the demand response start time Ts, and the demand response end time Te from the aggregator system 10 in step S14 of FIG. (S30). The consumer power management system 12 determines whether or not the demand response start time Ts has been reached (S32),
If not reached, the system waits for a predetermined time (S34).

When the demand response start time Ts is reached, a small power saving situation and a large power saving situation are obtained in parallel. First, for the former, the data collection unit 74 acquires the actual power consumption amount q2 for each sensor from the group of sensors 58 (of which power sensors) (S36), and obtains the actual power consumption amount Q2 for each customer (EMS unit). Calculate (S38) and store it in the results database 76.

The baseline calculation unit 78 acquires the baseline of the frame corresponding to the current time from the performance database (S40). The baseline calculation unit 78 acquires the past performance data 201 of the frame corresponding to the current time from the performance database 76, and calculates the baseline BL (S40). Further, the actual power saving actual amount calculation unit 80 subtracts the actual power consumption amount Q2 in EMS units obtained in step S38 from the baseline BL obtained in step S40, and sets this as the actual power saving amount b2 (S42). ). The obtained actual power saving amount b2 is sent to the aggregator system 10 (S44). Further, the small power saving adjusting unit 84 acquires the small power saving remaining amount b3 obtained by subtracting the small power saving actual amount b2 from the small power saving command amount b1 and calculates the small power saving adjustment amount b4 (S46).

Along with the calculation of the small power saving state, the power saving amount adjustment unit 92 calculates the large power saving state. The data transmitting / receiving unit 72 receives the large power saving command amount B1, the large power saving actual amount B2, and the number N1 of additional allocable customers from the aggregator system 10 (S48). The addition / subtraction unit 82B calculates a large power saving remaining amount B3 obtained by subtracting the large power saving performance amount B2 from the large power saving command amount B1 (S50). The large power saving adjustment unit 86 calculates the additional small power saving command amount b01 from the large power saving remaining amount B3 and the number N1 of additional allocable customers (S52).

The adjustment amount output unit 88 determines whether or not the small power saving remaining amount b3 is 0 or less, that is, whether or not the small power saving actual amount b2 is equal to or larger than the small power saving command amount b1 (S54). When the small power saving remaining amount b3 exceeds 0, that is, when the small power saving performance amount b2 has not reached the small power saving command amount b1, the adjustment amount output unit 88 sets the small power saving adjustment amount b4 as the fixed power saving command amount q1. It transmits to the equipment control part 90 (S56).

On the other hand, when the small power saving remaining amount b3 is equal to or less than 0, the adjustment amount output unit 88 sets the sum of both as a fixed power saving command amount q1 based on the small power saving adjustment amount b4 and the additional small power saving command amount b01, for example. The data is transmitted to the control unit 90 (S58). The facility control unit 90 performs power management of the subordinate devices 56 based on the received determined power saving command amount q1 (S60). The facility control unit 90 controls each device in the facility group by transmitting a control signal 103 to the facility group 56. Further, the consumer power management system 12 determines whether or not the demand response end time Te has been reached (S62), and if not, returns to step S36 and step S48. When the demand response end time Te is reached, this flow ends.

FIG. 8 shows an example of a power saving amount distribution flow according to the present embodiment. The graph illustrated in FIG. 8 takes time on the horizontal axis and power [kW] on the vertical axis. In this example, the baseline BL is assigned in 30 minutes and 1 frame. Moreover, the determination of the small power saving remaining amount b3 by the adjustment amount output unit 88 is performed at intervals of 5 minutes. Furthermore, in this example, the actual power saving amount represents the average value of power [kW] from 13:00.

The baseline BL in the frame from 13:00 to 13:30 is represented by A [kW]. Further, the small power saving command amount b1 in the frame from 13:00 to 13:30 is indicated by B [kW]. The adjustment amount output unit 88 determines whether or not the small power saving remaining amount b3 is 0 or less at intervals of 5 minutes. At 13:15, when the small power saving remaining amount b3 becomes 0 or less, that is, when the small power saving actual amount b2 (average value) becomes equal to or larger than the small power saving command amount b1, the adjustment amount output unit 88 is connected to the small power saving adjustment amount b4. The sum of the additional small power saving command amount b01 is set to the determined power saving command amount q1. Hereinafter, based on the determined power saving command amount q1 after setting, power management is performed on the subordinate devices 56.

Second Embodiment
As a modification of the example of FIGS. 2 and 4, as shown in FIGS. 9 and 10, the remaining power saving amount may be obtained in consideration of power saving prediction. FIG. 9 illustrates a functional block diagram of the aggregator system 10. A description of the functional units overlapping with the functional block diagram of FIG. 2 will be omitted as appropriate.

The data transmitting / receiving unit 28A receives the weather information 201 from the weather information provider 94. The weather information 201 is sent to the power saving prediction unit 96 (aggregator-side power saving prediction unit, large power saving prediction unit) and the data transmission / reception unit 28B. Although illustration is omitted, the power saving prediction unit 96 acquires the past large power saving performance amount B2 and the large power saving command amount B1 from the performance database 32. The power saving prediction unit 96 calculates a large power saving predicted amount B5 using an algorithm or the like indicating a causal relationship between the past large power saving actual amount B2, the large power saving command amount B1, and the weather information 201. In this algorithm, a causal relationship between past performance data (power saving performance amount and facility operation history) and weather conditions is learned using, for example, multiple regression modeling or a multilayer neural network. Alternatively, the large power saving predicted amount B5 may be obtained by collecting the small power saving predicted amount b5 sent from each consumer power management system 12.

The predicted large power saving amount B5 is a predicted value of the large power saving command amount B1 that is predicted to be calculated, for example, in the next frame (30 minutes) after a predetermined time from the current time point. Alternatively, the large power saving predicted amount B5 may be an increase / decrease amount from the large power saving command amount B1 at the current time point.

From the data transmission / reception unit 28B, in addition to the small power saving command amount b1, the large power saving command amount B1, the large power saving performance amount B2, the demand response start time Ts, the demand response end time Te, and the number N1 of additional allocable customers, The weather information 201 and the large power saving predicted amount B5 are transmitted to each consumer power management system 12.

FIG. 10 illustrates a functional block diagram of the consumer power management system. A description of the functional units overlapping with the functional block diagram of FIG. 4 will be omitted as appropriate.

The weather information 201 is transmitted to the power saving prediction unit 98 (EMS side power saving prediction unit, small power saving prediction unit) via the data transmission / reception unit 72. Although illustration is omitted, the power saving prediction unit 98 obtains the past small power saving actual amount b2 and the small power saving command amount b1 from the result database 76. Similarly to the power saving prediction unit 96, the power saving prediction unit 98 calculates the small power saving predicted amount b5 using an algorithm or the like indicating the causal relationship between the past small power saving actual amount b2 and the small power saving command amount b1 and the weather information 201. To do. The small power saving predicted amount b5 is a predicted value of the small power saving command amount b1 that is predicted to be calculated, for example, in the next frame (30 minutes) after a predetermined time from the current time point. Alternatively, the predicted power saving amount b5 may be an increase / decrease amount from the current power saving command amount b1.

The addition / subtraction unit 82A adjusts the power saving command amount b1 or the power saving actual amount b2 based on the power saving predicted amount b5. For example, the small power saving predicted amount b5 is further subtracted from the value obtained by subtracting the small power saving command amount b1 from the small power saving command amount b1 to obtain the small power saving remaining amount b3.

Similarly, the addition / subtraction unit 82B adjusts the large power saving command amount B1 or the large power saving performance amount B2 based on the large power saving predicted amount B5. For example, the large power saving predicted amount B5 is further subtracted from the value obtained by subtracting the large power saving command amount B1 from the large power saving command amount B1 to obtain the large power saving power remaining amount B3. In addition, the additional small power saving command amount b01 is calculated from the large power saving remaining amount B3.

The adjustment amount output unit 88 sets a definite power saving command amount q1 based on the small power saving remaining amount b3. That is, if the small power saving command amount b1 is 0 or less, the sum of the small power saving adjustment amount b4 and the additional small power saving command amount b01 becomes the fixed power saving command amount q1. On the other hand, if the small power saving command amount b1 exceeds 0, the small power saving adjustment amount b4 becomes the fixed power saving command amount q1.

If it is difficult to execute an algorithm that indicates the causal relationship between the past large / small power saving performance amount and the large / small power saving command amount and the weather information 201, such as when there is little past performance data, a so-called general-purpose model is used. A large / small power saving prediction amount may be obtained. For example, the general-purpose model is created from the performance data of other customers whose building scale, power usage tendency, contract power, etc. are similar. In obtaining the power saving prediction amount, whether to use the above-described algorithm or the general-purpose model may be determined based on the number of data points stored in the

performance databases

32 and 76.

<Other embodiments>
In the above-described embodiment, the large power saving performance amount B2 is sent from the aggregator system 10, but is not limited to this form. For example, all the consumer

power management systems

power management systems

12, 12,.・ Send to Each consumer power management system 12 may calculate the large power saving performance amount B2 by adding the acquired small power saving performance amounts b2. For example, each consumer

power management system

power management systems

12, 12,. To do.

Token ring communication may be used instead of broadcast. For example, an arbitrary consumer power management system 12 adds its own small power saving performance amount b2 to the small power saving performance amount b2 sent from its upstream (front) and sends (circulates) data on the loop. The aggregator system 10 may monitor whether or not the communication by the token ring is interrupted. Moreover, you may arrange | position to the upstream, so that a consumer with big power-saving possible quantity q3 (remaining power) is large.

As described above, the consumer power management system 12 autonomously obtains the large power saving performance amount B2 without waiting for the reception of the large power saving performance amount B2 of the aggregator system 10, thereby calculating based on the large power saving performance amount B2. The additional small power saving command amount b01 can be quickly obtained.

In the above-described embodiment, the central device 48 (B-OWS) executes the power saving amount distribution flow on the customer power management system side. However, the present invention is not limited to this form. For example, the power saving amount distribution flow may also be executed by the digital controller 52 that controls the operation of the device 56. By executing the power saving amount distribution flow in units of devices, more detailed power management becomes possible.
