Description

  The present invention relates to a customer adjustment plan planning method and a customer adjustment plan planning device, and more particularly, to a customer adjustment plan planning method and a customer adjustment plan planning device that assist in managing energy reduction in a customer-side facility. .

  In recent years, with the nationwide shortage of electricity in Japan, not only efforts on the energy (electric power) supply side but also energy reduction efforts on the customer side are increasing in importance. In particular, in addition to energy-saving efforts that have been vigorously promoted so far, a demand response (DR) system that attracts power only when adjustments are required due to tight supply and demand, etc. is drawing attention.

  Demand response is a balance between power supply and demand by changing the power consumption pattern on the customer side to reduce power consumption, rather than increasing the power generation on the supply side, when power demand is likely to exceed supply. Is something to take.

  When a consumer side that consumes energy such as electricity, gas, heat, etc., implements a demand response in its own facility, it enters between each customer and the supply side, and distributes the power suppression amount to multiple consumers. Therefore, the role of the service provider that efficiently provides the demand response service becomes important. In general, this service provider is called an “aggregator”.

  When the aggregator receives a power demand suppression signal and power rate information from the supply side, the aggregator distributes the power suppression amount allocated to each consumer to a plurality of consumers belonging to the same demand response group that has concluded the power suppression contract. At this time, the aggregator determines the distribution of the power suppression amount by paying attention to the fairness among consumers based on the power saving effect and the environmental deterioration (see, for example, Patent Document 1).

JP 2012-165513 A

  By the way, in patent document 1 mentioned above, the parameter | index for distributing the electric power suppression amount is defined so that the fairness between consumers may be ensured by an aggregator. However, in terms of whether or not individual consumers can be satisfied only by ensuring the fairness by the aggregator, an index that is satisfactory to all consumers is not necessarily prepared. This was an obstacle for customers to decide to participate in demand response services.

  The present invention is for solving such a problem, and in addition to fairness, a customer adjustment plan for increasing the possibility of distributing the power suppression amount so that all consumers can get a sense of satisfaction. The object is to propose a method and a customer adjustment planning system.

  In order to achieve this object, the present invention provides a customer information acquisition unit (consumer information) that uses actual power consumption representing the amount of power consumed in the past for each of a plurality of consumers (A to E) to be managed. 10) a customer information acquisition step acquired from each of the plurality of consumers, and a total energy demand target that represents the total demand of power required for an arbitrary reference period for each of the plurality of consumers (AE). Based on the value (AE) and the ratio of the period from the past start point to the present point in the reference period relative to the reference period, the target value of the total power demand required from the start point to the present point An energy total demand target value calculation unit (11) that calculates the present energy total demand target value (AEi) to be expressed, and the plurality of consumers based on the actual power consumption The total energy demand actual value calculated by the total energy demand actual value calculation unit (12) representing the current total energy demand actual value (Ei) representing the total energy demand consumed from the start time to the present time for each of A to E). And calculating the ratio of the current total energy demand actual value (Ei) to the current total energy demand target value (AEi) and the current energy saving target achievement level (Li) for each of the plurality of consumers (AE). As an energy saving target achievement level calculation step calculated by the energy saving target achievement level calculation unit (13) and a customer candidate selection unit (Li) based on the energy saving target achievement level (Li) for each of the plurality of consumers (AE) 14) has a consumer candidate selection step of selecting candidates for consumers (A to E) to be power-suppressed.

  In the present invention, the consumer candidate selection step selects a consumer whose energy saving target achievement level (Li) is smaller than a specific threshold for each of the plurality of consumers (A to E) as the power suppression target candidate. To do.

  In this invention, in the said consumer candidate selection step, the said energy-saving target achievement level (Li) for every said several consumers (A-E) is set to the said electric power suppression object for the consumer which belongs to the low-order order of a specific ratio. Select as a candidate.

  In the present invention, a customer information acquisition unit that acquires, from the plurality of consumers, actual power consumption representing the amount of power consumed in the past for each of a plurality of consumers (A to E) to be managed. (10), an energy total demand target value (AE) representing the total demand of power required in an arbitrary reference period for each of the plurality of consumers (A to E), and the reference period with respect to the reference period Energy that calculates the current total energy demand target value (AEi) that represents the target value of the total power demand from the start time to the current time, based on the ratio of the period from the past start time to the current time The total demand target value calculation unit (11) and the total energy demand consumed from the start time to the current time for each of the plurality of consumers (AE) based on the actual power consumption The total energy demand actual value calculation unit (12) for calculating the actual energy total demand actual value (Ei), and the ratio of the current total energy demand actual value (Ei) to the current total energy demand target value (AEi) The energy saving target achievement level calculation unit (13) that calculates the current energy saving target achievement level (Li) for each consumer and the energy saving target achievement level (Li) for each of the plurality of consumers (AE) And a customer candidate selection unit (14) for selecting candidates for consumers (A to E) to be power-suppressed.

[Principle of the Invention]
Many customers (usually all customers) generally have numerical targets for energy conservation. On the other hand, the present invention has focused on the fact that measures for power saving by demand response are often effective for energy saving at the same time.

  That is, conventionally, when the aggregator determines the distribution of the power suppression amount for facilities such as office buildings owned by a plurality of customers, the degree of achievement of the energy saving target in each customer is not considered. For this reason, consumers can only acquire demand response incentives, which often have unstable effects and benefits depending on the operation, and this has been an obstacle when deciding to participate in demand response services.

  Therefore, the present invention refers to the current energy saving target achievement level with respect to the energy saving target value of the facility owned by each customer when determining the distribution of the power suppression amount by demand response, and finally achieves the energy saving target value. The demand response is preferentially executed from the facility of the customer who is predicted to be difficult to perform as an index.

  The reason is that it is possible to easily achieve the energy saving target value of the facility of the customer with low energy saving target achievement by executing the demand response in preference to the facility of the customer with low achievement level of the energy saving target. This is because it is possible to give a sense of satisfaction in addition to fairness to consumers who have low achievement of energy saving targets.

  Here, the power suppression by demand response is not limited to a single facility as a consumer, but to each business operator who has multiple facilities as a consumer, or for each tenant occupying a facility as a consumer. It is also possible to suppress.

  Thereby, the present invention can provide an effect that it is possible to contribute to raising the energy saving target achievement level of the consumer at the same time giving an incentive of demand response to a consumer having low energy saving target achievement level, Thus, the possibility of giving strong motivation when participating in the demand response service to the consumer is increased. An energy management system using such a customer adjustment planning system that embodies the principle of the present invention will be described below.

[Configuration of energy management system]

The energy management device 2 and the facility management devices 3A to 3E of the facility management device group 3 are connected to each other via a network 4 such as the Internet.

[Configuration of facility management device]
The facility management apparatus 3A includes an information processing apparatus such as a personal computer, and uses energy (electric power) used (consumed) in the facility A managed by the facility management apparatus 3A in response to a demand response request from the energy management apparatus 2. It has a power suppression function to suppress. Since all the facility management apparatuses 3A to 3E have the same configuration, only the configuration of the facility management apparatus 3A will be described here for convenience.

  This facility management apparatus 3A includes an actual power consumption calculation unit 3a, a target power consumption registration unit 3b, a suppressable power estimation unit 3c, and a power suppression control unit 3d as main functional units. The facility management apparatus 3A is realized by installing a computer program (software) in a computer (hardware) including a CPU (Central Processing Unit), a memory, an interface, and the like.

Further, the computer program may be provided in a state of being stored in a computer-readable recording medium or a storage device, or may be provided via an electric communication line.

  The actual power consumption calculation unit 3a is, for example, the daily power consumption (hereinafter referred to as “actual power consumption”) consumed per predetermined unit time in the past (for example, the previous day) of the facility A that is the power management target. And the “actual power consumption” is stored in the internal memory.

  The target power consumption registration unit 3b may consume, for example, an upper limit power consumption for one month (hereinafter referred to as “target power consumption”) that may be consumed in a predetermined period in the future (for example, the next month) of the facility A that is a power management target. Is registered in the internal memory.

  The controllable power estimation unit 3c is set in advance according to the energy usage results based on the operating status of the load equipment in the facility A at each time, for example, the number of operating air conditioners, the set temperature, the set PMV (Predicted Mean Vote), etc. For example, in a certain facility, the power that can be suppressed in a certain time zone (hereinafter referred to as “suppressable power”) is estimated at certain time intervals (for example, every hour). The suppressible power estimation value is stored in the internal memory while being sequentially updated. The estimation method of the suppressible power estimation value by the suppressible power estimation unit 3c is not limited to this, and the above-described suppressable power estimation value can be obtained by a known estimation method or a combination thereof.

  The facility management apparatus 3A uses the actual power consumption calculated by the actual power consumption calculation unit 3a, the target power consumption registered by the target power consumption registration unit 3b, and the reducible power estimation estimated by the reducible power estimation unit 3c. The value is transmitted as facility information (customer information) to the energy management apparatus 2 via the network 4 via an interface (not shown).

  The power suppression control unit 3d of the facility management apparatus 3A receives a power suppression request from the power suppression control apparatus 2b of the energy management apparatus 2 and actually executes the power suppression process according to the power suppression request.

[Configuration of energy management equipment]
The energy management device 2 is realized by installing a computer program (software) in a computer (hardware) including a CPU (Central Processing Unit), a memory, an interface, and the like, and a customer adjustment plan planning device in the energy management device 2 Each part of 2a and the electric power suppression control apparatus 2b is implement | achieved when the various hardware resources of a computer and a computer program cooperate. Further, the computer program may be provided in a state of being stored in a computer-readable recording medium or a storage device, or may be provided via an electric communication line.

  The customer adjustment plan planning device 2a is composed of an information processing device such as a personal computer, and should be suppressed according to demand response requests from the power supply side in a plurality of facilities A to E managed by the facility management devices 3A to 3E. It has a power suppression amount distribution function that distributes and allocates the power suppression amount to the individual facilities A to E.

  This customer adjustment plan planning device 2a includes a facility information acquisition unit 10 as a customer information acquisition unit that acquires facility information transmitted from the facility management devices 3A to 3E, and a monthly unit or a year including the current time in the facilities A to E. While calculating the target value of the total demand for electricity required in the unit reference period (hereinafter referred to as the total energy demand target value AE) for each of the facilities A to E, the period start date of the reference period To the current i (i = integer greater than or equal to 0 representing the number of days that have passed since the start date of the period) (Referred to as target value AEi) for each of the facilities A to E, the total energy demand target value calculation unit 11 and the power actually consumed from the start date of the reference period to the present (current time). The total energy demand actual value calculation unit 12 for calculating the cumulative value of energy (hereinafter referred to as the total energy demand actual value Ei), the total energy demand actual to the present relative to the current total energy demand target value AEi to the present Energy saving target achievement calculation unit 13 for calculating the energy saving target achievement degree Li, which is the ratio when the value Ei is higher (energy saving target is not achieved) or lower (energy saving target is achieved), and the energy saving target is not reached A priority customer candidate selection unit 14 as a customer candidate selection unit that preferentially selects a facility as a candidate for a power suppression target customer, and a customer candidate selected with priority by the priority consumer candidate selection unit 14 Is provided with a priority consumer candidate information output unit 15 that outputs the information (hereinafter referred to as priority consumer candidate information) to the power suppression control device 2b. Yes.

  The priority customer candidate information output unit 15 outputs the priority customer candidate information of the customer candidates selected with priority by the priority customer candidate selection unit 14 to the power suppression control device 2b. By presenting the priority customer candidate information to the customer, the customer adjustment plan designed by the customer adjustment plan planning device 2a can be recognized by the customer.

  By the way, in the power suppression control device 2b, the priority consumer candidate information is received from the priority consumer candidate information output unit 15, but the consumer candidate corresponding to the priority consumer candidate information is directly used as the power suppression target consumer. Not necessarily. Normally, priority is given to the candidate of the customer selected by the customer adjustment planning device 2a, and the selection criterion such as fairness, which is different from the achievement level of the energy saving target, is considered until the demand response power suppression requirement is satisfied. Thus, a consumer is selected, and a consumer targeted for final power suppression is determined. However, in this Embodiment, the candidate of the consumer selected by the consumer adjustment plan planning apparatus 2a shall be determined as a consumer of electric power suppression object as it is.

  The power suppression control device 2 b includes a power suppression customer determination unit 16 and a power suppression request transmission unit 17. When the power suppression consumer determination unit 16 acquires the priority consumer candidate information from the priority consumer candidate information output unit 15, the power suppression control device 2b acquires the facility management apparatus for the power suppression facility corresponding to the priority consumer candidate information. The power suppression request for causing the power suppression request transmitting unit 17 to execute the power suppression process is generated and transmitted to any of 3A to 3E.

  Next, the configuration and processing of each unit in the customer adjustment plan planning device 2a will be described. The facility information acquisition unit 10 includes an actual power consumption acquisition unit 10a, a target power consumption acquisition unit 10b, and a suppressable power estimation value acquisition unit 10c. The actual power consumption acquisition unit 10a acquires and holds the actual power consumption from the facility information received from the facility management devices 3A to 3E. The target power consumption acquisition unit 10b acquires and holds the target power consumption from the facility information received from the facility management apparatuses 3A to 3E. The controllable power estimated value acquisition unit 10c acquires and stores a controllable power estimated value from the facility information received from the facility management apparatuses 3A to 3E.

  The total energy demand target value calculation unit 11 is a facility over a reference period such as a year or month based on the target power consumption amount acquired by the target power consumption amount acquisition unit 10b of the facility information acquisition unit 10 from the facility management devices 3A to 3E. The total energy demand target value AE for each of A to E is calculated, and this total energy demand target value AE is held.

  The total energy demand target calculation unit 11 calculates the ratio of the number of days that have elapsed from the start date of the reference period to the current point i during the period (hereinafter referred to as “elapsed days”) Ti and the total number of days T of the reference period. Based on the following (Equation 1), the current total energy demand target value AEi from the period start date to the current i is calculated for each facility A to E by apportioning the total energy demand target value AE for the base period. Hold.

  AEi = AE × Ti / T …………………………………………………………………… (Formula 1)

  The total energy demand actual value calculation unit 12 calculates the actual power consumption acquired by the actual power consumption acquisition unit 10a of the facility information acquisition unit 10 from the facility management devices 3A to 3E from the start date of the reference period to the current i during the period. By accumulatively adding up to the current total energy demand actual value Ei from the period start date to the current i, it is calculated for each of the facilities A to E and held.

  The energy saving target achievement level calculation unit 13 calculates the ratio between the current total energy demand target value AEi and the current total energy demand actual value Ei at the current i during the period from the start date of the reference period and the current total energy demand target value AEi. Based on the following (Formula 2), energy saving target achievement level Li is obtained for each facility A to E.

  Li = {1+ (AEi−Ei) / AEi} × 100 [%] ………………………………… (Formula 2)

  Here, FIG. 2 shows an example of calculation of the energy saving target achievement level Li obtained by (Equation 2) described above. In this case, in Example 1, since the current total energy demand target value AEi (100 kWh) and the current total energy demand actual value Ei (100 kWh) are the same, the energy saving target achievement level Li is 100%, and the current i It is shown that energy saving targets have been achieved.

  In Example 2, since the current total energy demand actual value Ei (80 kWh) is lower than the current total energy demand target value AEi (100 kWh), the energy saving target achievement level Li is 120%. It is shown that the energy saving target has been achieved.

  Furthermore, in Example 3, since the current total energy demand actual value Ei (120 kWh) is higher than the current total energy demand target value AEi (100 kWh), in this case, power suppression is insufficient at this time. Achievement of energy saving target Li is 80%, indicating that energy saving target has not been achieved at present i.

  The energy saving target achievement level calculation unit 13 can obtain the energy saving target achievement level Li based on the following (Formula 3) instead of the above (Formula 2).

  Li = exp {(AEi−Ei) / AEi} × 100 [%] …………………………………… (Formula 3)

  FIG. 3 shows an example of calculation of the energy saving target achievement level Li obtained by (Equation 3) described above. In this case, in Example 1, since the current total energy demand target value AEi (100 kWh) and the current total energy demand actual value Ei (100 kWh) are the same, the energy saving target achievement level Li is 100%, and the current i It is shown that energy saving targets have been achieved.

  In Example 2, since the current total energy demand actual value Ei (80 kWh) is lower than the current total energy demand target value AEi (100 kWh), the energy saving target achievement level Li is 122%. It is shown that the goal has been achieved.

  Furthermore, in Example 3, since the current total energy demand actual value Ei (120 kWh) exceeds the current total energy demand target value AEi (100 kWh), in this case, power suppression is insufficient at this time. Achievement of energy saving target Li is 82%, indicating that energy saving target has not been achieved at present i.

  As described above, the energy saving target achievement level calculation unit 13 can obtain the energy saving target achievement level Li not only by the above-described (Formula 2) and (Formula 3) but also by various calculation formulas.

  The priority customer candidate selection unit 14 refers to the energy saving target achievement level Li at the current i for each of the facilities A to E managed by the facility management apparatuses 3A to 3E, and finally the energy saving target achievement level Li is not achieved. The facility of such a consumer is prioritized and the candidate of the facility used as the power suppression object of a demand response is determined.

  The priority customer candidate selection unit 14 selects, as a priority facility candidate (customer candidate), that the energy saving target achievement level Li of the facilities A to E is smaller than a predetermined energy saving target achievement level threshold of 80%, for example. Among the priority facility candidates, among the total number of facilities A to E (in this case, five buildings of facilities A to E), for example, the number that is a ratio of the lower order selection threshold 40%, in this case, the degree of achievement of the energy saving target Select two buildings from the lower side of Li as priority facility candidates.

  However, it is not restricted to this, The priority consumer candidate selection part 14 uses only the energy saving target achievement threshold 80% of the energy saving target achievement degree Li of the facilities AE without using the lower-order order selection threshold. It can be selected as a priority facility candidate (customer candidate). Further, the priority consumer candidate selection unit 14 uses only the lower-order order selection threshold 40% of the total number of the buildings A to E without using the energy saving target achievement threshold, that is, the energy saving target achievement Li Two buildings from the lower side can be selected as candidates for priority facilities.

  The priority customer candidate information, which is information on the priority facility candidate selected in this way, is determined from the priority consumer candidate selection unit 14 via the priority customer candidate information output unit 15 and the power suppression consumer determination of the power suppression control device 2b. When the unit 16 receives, the power suppression consumer determination unit 16 determines that the energy saving target achievement level Li is smaller than the energy saving target achievement level threshold 80 [%] and corresponds to two buildings from the lower side of the energy saving target level Li Priority is given to the facility candidates, and the facility is selected in consideration of selection criteria such as fairness, which is different from the energy saving target achievement level Li, from the entire facilities A to E to the demand response power suppression requirement amount, This is determined as a power suppression facility (power suppression consumer) that is a target of execution of demand response.

  For example, the demand response power suppression request amount in the demand response time zone for the facilities A to E is 80 [kW], and the facility management apparatuses 3A to 3E for the facilities A to E targeted for the demand response as shown in FIG. The estimated power suppression values in the demand response time zones of the facilities A to E are facility A: 30 [kW], facility B: 50 [kW], facility C: 20 [kW], facility D: 40 [ kW], facility E: Assuming the case of 10 [kW], Examples 1 to 4 in which the customer of the power suppression facility that is the final power suppression target is determined by the power suppression customer determination unit 16 will be described.

  As shown in FIG. 5, in the case of Example 1, since there is no facility whose energy saving target achievement level Li is smaller than the energy saving target achievement level threshold 80%, the priority facility candidate is not selected. In this case, since there is no candidate for a priority facility, for example, a facility A having a suppressible power estimated value of 30 [kW] and a facility B having a suppressible power estimated value of 50 [kW] are additionally selected. If two buildings of the facility B are determined as power suppression facilities to be subjected to demand response, the demand response power suppression request amount of 80 [kW] in the demand response time zone can be achieved.

  In the case of Example 2, since there is only the facility A having the energy saving target achievement level Li (70%) whose energy saving target achievement level Li is smaller than the energy saving target achievement level threshold 80%, this facility A is selected as a priority facility candidate. Because the priority facility candidate is only one facility A, and the total number of facilities A to E is less than the number (2 buildings) of the lower order selection threshold 40%, the facility A is the priority facility Selected as a candidate.

  In this case, since the controllable power estimated value of the facility A is 30 [kW], for example, a facility B whose controllable power estimate is 50 [kW] is additionally selected, and two buildings of the facility A and the facility B are demanded. If it is determined as a power suppression facility that is a response execution target, the demand response power suppression requirement amount of 80 [kW] in the demand response time zone can be achieved, and the energy saving target achievement level Li of the facility A can be increased. Can do.

  In the case of Example 3, there is a facility B having an energy saving target achievement degree Li (60%) and a facility D having an energy saving target achievement degree Li (70%) where the energy saving target achievement degree Li is smaller than the energy saving target achievement degree threshold 80%. The facility B and the facility D are set as priority facility candidates, and the priority facility candidates are only the facility B and the facility D, and the lower order order selection threshold value among the total number of the facilities A to E is five. Since the number is less than 40% (two buildings), the facilities B and D are selected as priority facility candidates.

  In this case, the controllable power estimation value of the facility B is 50 [kW], and the controllable power estimation value of the facility D is 40 [kW]. If two buildings of the facility D are determined as power suppression facilities to be subjected to demand response, the demand response power suppression request amount of 80 [kW] in the demand response time zone can be achieved, and the facility B and the facility D Each energy saving target achievement level Li can be raised.

  In the case of Example 4, facility A with energy saving target achievement level Li (70%), facility C with energy saving target achievement level Li (60%), energy saving target achievement level Li is less than 80% of energy saving target achievement level threshold Because there is a facility E of degree Li (65%), this facility A, facility C, and facility E are candidates for priority facilities, but there are three priority facility candidates: facility A, facility C, and facility E. Since the total number of facilities A to E exceeds the number (2 buildings) that is the lower side order selection threshold 40%, the lower order facility C and facility E with low energy saving target achievement degree Li Only two buildings are selected as priority facility candidates.

  In this case, the controllable power estimation value of the facility C is 20 [kW], and the controllable power estimation value of the facility E is 10 [kW]. Therefore, for example, the facility where the controllable power estimation value is 50 [kW] If B is additionally selected, and the three buildings, Facility B, Facility C, and Facility E, are determined as power suppression facilities to be subjected to demand response, a demand response power suppression request amount of 80 [kW] in the demand response time zone is obtained. It can be achieved, and the energy saving target achievement level Li of the facility C and the facility E can be raised respectively.

  When the power suppression facility is determined by the power suppression consumer determination unit 16 as described above, the power suppression customer determination unit 16 outputs the determined power suppression facility identification information to the power suppression request transmission unit 17. The power suppression request transmission unit 17 transmits a power suppression request for executing the power suppression process to the facility management devices 3A to 3E based on the identification information of the power suppression facility determined by the power suppression customer determination unit 16.

[Operation of energy management device]
In the energy management device 2, an operation for determining a power suppression facility from the facilities A to E based on the facility information received from the facility management devices 3A to 3E, and causing the power suppression facility to execute a power suppression process. This will be described with reference to the flowchart of FIG.

  The energy management device 2 enters from the start step of the routine RT1, moves to the next step SP1, and acquires facility information from the facilities A to E by the facility information acquisition unit 10, respectively.

  In step SP2, the energy management apparatus 2 calculates the current total energy demand target value AEi at the current time i for each of the facilities A to E by the total energy demand target value calculation unit 11.

  In step SP3, the energy management device 2 calculates the current total energy demand actual value Ei at the present time i for each of the facilities A to E by the total energy demand actual value calculation unit 12.

  In step SP4, the energy management apparatus 2 uses the energy saving target achievement level calculation unit 13 to obtain the energy saving target achievement level Li for each of the facilities A to E based on the current total energy demand target value AEi and the current total energy demand actual value Ei.

  In step SP5, the energy management apparatus 2 selects a priority facility candidate (facility A in the case of Example 4) in which the energy saving target achievement level Li is lower than the energy saving target achievement level threshold (80% in this case) among the facilities A to E. , Facility C, facility E), and among the priority facility candidates, the degree of achievement of the energy saving target corresponding to the lower order order selection threshold (40% in this case) from among the total number of facilities A to E Two facilities from the lower side of Li are selected as priority facility candidates (in the case of Example 4, facility C and facility E).

  In step SP6, the energy management apparatus 2 gives priority to the priority facility candidates (in the case of Example 4, the facility C and the facility E), and considers a selection criterion such as fairness that is different from the energy saving target achievement level Li. Then, the final power suppression facility (in the case of Example 4, for example, the facility B, the facility C, and the facility E) is determined.

  In step SP7, the energy management device 2 determines the facility management device (facility management device 3B in the case of Example 4) corresponding to the selected power suppression facility (facility B, facility C, facility E in the case of Example 4). 3C, 3E), a power suppression request is generated and transmitted from the power suppression request transmission unit 17 of the power suppression control device 2b.

  As a result, the power suppression control unit 3d of the facility management apparatus (facility management apparatuses 3B, 3C, and 3E in the case of Example 4) follows the power suppression request received from the power suppression request transmission unit 17 in the demand response time zone. By suppressing the power usage of the power suppression facility (facility B, facility C, facility E in the case of Example 4), the demand response power suppression request amount of 80 [kW] can be achieved, and demand The energy saving target achievement level Li of each of the priority facility candidates (facility C and facility E in the case of Example 4) selected by the house adjustment planning device 2a can be increased.
