Description

Technical Field

[0001] The present invention relates to an energy management system, a program, and an energy management method.

Background Art

[0002] An EMS (Energy Management System) that manages the power used by multiple facilities is known. For example, the power control system of Patent Document 1 has the function of an EMS server that manages the power of a group of facilities such as stores by comparing it with a target value. When an event is planned at a facility where the power consumption is different from normal, the power control system changes the target value of the power. Specifically, when an event such as a morning market or a demonstration sale is planned, the planned event information is input to the EMS server, and the EMS server can calculate a target correction value using the actual value of the power consumption of the same type of event in the past by correcting the target value for each event.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In recent years, a regional EMS (Energy Management System) that manages energy in units of areas (regions) instead of in units of facilities such as buildings has been studied. The players participating in the regional EMS include various players such as players related to the entire region, players related to facilities, and players related to equipment within the facilities. By jointly using the energy within the area by these various players in the regional EMS, the energy cost within the area can be reduced.

[0005] However, while the power control system described in Patent Document 1 above claims to be able to correct the target power consumption of load equipment when an event is planned and manage load equipment appropriately with high accuracy, it does not take into account changes in energy across the entire region when energy is shared among multiple facilities scattered throughout the region, such as in a regional EMS.

[0006] This disclosure is made in light of these circumstances and aims to provide an energy management system, program, and energy management method that enables the smooth operation of a regional EMS while taking into account changes in energy throughout the region when various players participating in the regional EMS jointly utilize energy.

[0008] Another aspect of this disclosure is a program that causes a computer in an energy management system for managing the energy of multiple facilities to perform the steps of: inputting energy increase / decrease factors that affect facility energy information calculated by the facility's energy management system; transmitting the energy increase / decrease factors to a first server device; and calculating area energy information based on the energy increase / decrease factors.

[0009] Another aspect of this disclosure is an energy management method for managing the energy of multiple facilities, wherein the energy management system performs the steps of: inputting energy increase / decrease factors that affect facility energy information calculated by the facility's energy management system; transmitting the energy increase / decrease factors to a first server device; and calculating area energy information based on the energy increase / decrease factors.

The power supply device 850 includes equipment that supplies power to the energy supply facility 600 from the power grid 800 described above. The fuel supply device 860 includes equipment that supplies fuel to the energy supply facility 600.

[0023] The area energy management device 100 is an information processing device that acquires information via a communication network and performs various processing tasks. The area energy management device 100 includes, for example, a control processing unit 110. The control processing unit 110 is implemented, for example, by a computer such as a CPU (Central Processing Unit) executing a program stored in program memory.

[0024] The control processing unit 110 calculates, for example, energy demand forecast information for the target area and calculates energy purchase plans, sales plans, and energy storage plans. Energy demand forecast information includes, for example, predicted values ​​of energy demand in one-minute increments for a day. Energy purchase plans include, for example, information showing the amount of energy to be purchased in 10-30 minute increments for a day. Energy sales plans include, for example, information showing the amount of energy to be sold in 10-30 minute increments for a day. Energy storage plans, such as thermal storage plans, include, for example, information showing the amount of energy stored in the energy supply facility 600 in 10-30 minute increments for a day.

[0025] The control processing unit 110 calculates start-up and stop-down plans for multiple pieces of equipment included in the energy supply facility 600 based on energy demand forecast information and energy purchase plans, sales plans, energy storage plans, equipment models, and equipment characteristic information. The start-up and stop-down plans include information such as the start-up and stop-down timings for each piece of equipment included in the energy supply facility 600, in one-minute increments. The control processing unit 110 calculates control target information according to the energy storage plan and the start-up and stop-down plans.

[0026] The control processing unit 110 may output the calculated control target information to the operator terminal device 120. The control processing unit 110 can output the calculated control target information to the equipment included in the energy supply facility 600 and control the equipment. The control processing unit 110 may change the control target information of each piece of equipment based on feedback information from the energy supply facility 600. If the control processing unit 110 changes the control target information, it may notify the operator terminal device 120 of the change in the control target information of each piece of equipment.

[0027] The operator terminal device 120 is an information processing device operated by an operator in the target area. The operator terminal device 120 receives various notifications from the control processing unit 110 and displays the status of each piece of equipment in the energy supply facility 600. Upon receiving an operation from the operator, the operator terminal device 120 transmits control instruction information for the equipment included in the energy supply facility 600 to the area energy management device 100. The control processing unit 110 controls the equipment included in the energy supply facility 600 according to the control instruction information.

[0028] The energy supply facility 600 supplies energy to the energy recipient facility 700. The equipment included in the energy supply facility 600 includes, for example, a boiler 602, a CGS (cogeneration system) 604, a cooling tower 606, an absorption chiller 608, a turbo chiller 610, a heat exchanger for heat dissipation 612, a thermal storage tank 614, and media transfer devices (not shown) such as pumps and valves associated with these devices. In this embodiment, the equipment included in the energy supply facility 600 generates energy using electricity supplied from the power supply facility 850 and / or fuel supplied from the fuel supply facility 860. For example, the boiler 602 and the CGS 604 are heating devices that heat the medium. For example, the cooling tower 606, absorption chiller 608, turbo chiller 610, and heat exchanger for heat dissipation 612 are cooling devices that cool the medium. The energy supply facility 600 has a control device (not shown) for controlling the output of each piece of equipment. The control device may include, for example, an output control device dedicated to the equipment, a centralized control device called a central monitoring system, a DCS (Distributed Control System), a PLC (Programmable Control System), and other control terminals. The area energy management device 100 transmits control target information to the control device of the energy supply facility 600 and modifies the operation of the equipment.

[0029] The energy supply destination facility 700 includes customer equipment that consumes energy supplied from the energy supply facility 600. Energy supply destination facility 700A includes, for example, customer equipment such as factories and residences located in the target area. Energy supply destination facility 700B includes, for example, building facilities located in the target area, tenant facilities included in building facilities, etc. Each of the energy supply destination facilities 700A and 700B is equipped with a measurement unit 710. The measurement unit 710 measures the energy information of each energy supply destination facility 700. Energy information is used to calculate indicators for 700 energy supply destination facilities, such as power consumption, power supply or demand, power generation, gas usage, medium flow rate or medium pressure, and power buying and selling. The indicators for 700 energy supply destination facilities are, for example, energy consumption, energy reduction, total energy (energy generation - energy consumption), CO2 emissions or CO2 reduction, and a displayed score that scores these values.

[0030] The EMS server device 200 includes, for example, a first notification destination setting unit 202 and a first calculation unit 204. The first notification destination setting unit 202 and the first calculation unit 204 are implemented, for example, by a computer such as a CPU executing a program stored in program memory. The first notification destination setting unit 202 sets facility notification destination information, which is set for each energy supply destination facility 700. The facility notification destination information is, for example, a table data that associates information identifying the energy supply destination facility 700 with notification destination information.

[0031] The first calculation unit 204 calculates area energy information based on energy increase / decrease factors. Area energy information is energy information for the entire target area, based on energy information obtained from multiple energy supply facilities 700 included in the target area. Energy increase / decrease factors are information that affects the facility energy information calculated by the facility server devices 300 (energy management system, BEMS) of the energy supply facility 600 and the energy supply facilities 700. Facility energy information is energy information for each energy supply facility 700.

[0032] Energy increase / decrease factors may include at least one of facility event information and expected attendance information during facility events. Facility event information refers to events that increase or decrease energy consumption compared to normal times, such as events held in event spaces within buildings or professional competitions held at sports facilities, which result in a sharp increase in energy consumption. Expected attendance information during facility events includes information such as the expected daily attendance for every 700 energy-supplied facilities and the expected attendance for each time period.

[0033] Energy increase / decrease factors may include equipment maintenance information. Equipment maintenance information includes, for example, the inspection date and time of the air conditioning equipment at the energy supply recipient facility 700, or other information that is expected to cause a sharp decrease in energy consumption at the energy supply recipient facility 700.

[0034] The first calculation unit 204 may select target facilities based on area energy information calculated by the EMS server device 200. For example, the first calculation unit 204 may select energy supply facilities 600 or energy recipient facilities 700 with high electricity consumption, or energy recipient facilities 700 with rapidly increasing electricity consumption, as target facilities to cooperate in saving electricity. The first calculation unit 204 may register the amount of electricity that can be saved for each energy recipient facility 700 and select energy recipient facilities 700 with large amounts of electricity that can be saved as target facilities to cooperate in saving electricity, prioritizing their selection. The first calculation unit 204 may select energy recipient facilities 700 that have previously offered to cooperate in saving electricity and registered.

[0035] The EMS administrator terminal 210 includes, for example, a first acquisition unit 212, a first notification control unit 214, a first target acquisition unit 216, a notification unit 218, and a first output control unit 220. The first acquisition unit 212, the first notification control unit 214, the first target acquisition unit 216, the notification unit 218, and the first output control unit 220 are implemented, for example, by a computer such as a communication circuit or CPU executing a program stored in program memory. The first acquisition unit 212 acquires facility notification destination information from the EMS server device 200 when requesting cooperation in saving electricity. Based on the facility notification destination information acquired by the first acquisition unit 212, the first notification control unit 214 causes at least one of the multiple energy supply destination facilities 700 to send a facility cooperation notification indicating a request for cooperation in saving electricity. The first notification control unit 214 may select at least one of a plurality of energy supply destination facilities 700 based on facility notification destination information and send a facility cooperation notification to the notification destination of the selected energy supply destination facility 700. Based on the required amount of energy saving, which is the amount of electricity to be reduced by energy saving, and the amount of energy saving possible for each energy supply destination facility 700, the first notification control unit 214 may send facility cooperation notifications to one or more energy supply destination facilities 700 to satisfy the required amount of energy saving.

[0036] The first target acquisition unit 216 acquires information indicating the target facility selected by the first calculation unit 204. The first notification control unit 214 sends a facility cooperation notification to the notification destination set in the facility notification destination information for the target facility whose information has been acquired by the first target acquisition unit 216. The notification unit 218 notifies the administrator of the energy management system 1 based on area energy information for the entire target area. The notification unit 218 may also notify the administrator when it receives a request for cooperation in saving electricity from the area energy management device 100. The notification unit 218 may output, for example, a message via a display device or speaker indicating that it has received a request for cooperation in saving electricity. The first output control unit 220 outputs a request screen to request cooperation in saving electricity based on a notification to the administrator of the energy management system 1. Based on the operation entered on the request screen, the first output control unit 220 prompts the user to select at least one of the multiple energy supply destination facilities 700.

[0037] Figure 4 shows an example of a request screen presented to the administrator of the energy management system 1 in the embodiment. As shown in Figure 4(a), the EMS administrator terminal 210 displays, for example, regional supply and demand forecast information, external procurement forecast information, regional target value information, and a button for requesting cooperation from the region. When the button for requesting cooperation from the region is selected, the EMS administrator terminal 210 automatically sends a facility cooperation notification to the target facility selected by the first calculation unit 204.

[0038] When the cooperation request button for the region is selected, the EMS administrator terminal 210 may display the cooperation recipient selection screen as a request screen, as shown in Figure 4(b). The cooperation recipient selection screen includes information showing a list of target facilities selected by the first calculation unit 204, and a cooperation request notification button. When the cooperation request notification button is selected, the EMS administrator terminal 210 sends a facility cooperation notification to one or more energy supply destination facilities 700 selected in the list of target facilities.

[0039] The facility server device 300 includes, for example, an input unit 302, a communication control unit 304, a search unit 306, a storage unit 308, a second calculation unit 310, a second notification destination setting unit 312, a selection unit 314, and an equipment setting unit 316. The input unit 302, communication control unit 304, search unit 306, storage unit 308, second calculation unit 310, second notification destination setting unit 312, selection unit 314, and equipment setting unit 316 are implemented, for example, by a computer such as a communication circuit and CPU executing a program stored in program memory.

[0040] The input unit 302 receives information indicating energy increase / decrease factors that affect the facility energy information calculated by the facility server device 300. For example, the input unit 302 receives information indicating energy increase / decrease factors transmitted based on operations to the facility administrator terminal 400. The communication control unit 304 causes the EMS server device 200 to transmit information indicating energy increase / decrease factors. As a result, the first calculation unit 204 can calculate area energy information based on the energy increase / decrease factors.

[0041] When an energy increase / decrease factor is input by the input unit 302, the memory unit 308 stores the energy increase / decrease factor and the increase / decrease value of the facility energy information in association with it. When the next energy increase / decrease factor is input, the search unit 306 searches the memory unit 308 for past increase / decrease values ​​of the facility energy information stored in the memory unit 308, assuming that information indicating an energy increase / decrease factor is already stored in the memory unit 308. This allows the communication control unit 304 to transmit the energy increase / decrease factor and the past increase / decrease value of the facility energy information corresponding to that factor.

[0042] When the second calculation unit 310 receives energy increase / decrease factors from the input unit 302, it calculates a future predicted value of the facility energy information based on the energy increase / decrease factors stored in the storage unit 308 and the past increase / decrease values ​​of the facility energy information. When the second calculation unit 310 receives energy increase / decrease factors from the input unit 302, it may generate a prediction model learned by machine learning using the energy increase / decrease factors stored in the storage unit 308 and the past increase / decrease values ​​of the facility energy information, and obtain a future predicted value of the facility energy information from the prediction model. The prediction model is a machine learning model that has been learned using energy increase / decrease factors, past increase / decrease values ​​of the facility energy information and future predicted values ​​of the facility energy information as training data. The prediction model receives energy increase / decrease factors as input during inference and outputs a future predicted value of the facility energy information. As a result, the second calculation unit 310 can calculate a future predicted value of the facility energy information using the prediction model. The communication control unit 304 can transmit energy increase / decrease factors and future predicted values ​​of facility energy information.

[0043] The second notification destination setting unit 312 sets equipment notification destination information for each energy supply destination facility 700, which includes notification destinations for multiple equipment operators. The equipment notification destination information is, for example, a table data that associates information identifying the energy supply destination facility 700, information identifying the equipment in the energy supply destination facility 700, and information indicating the notification destinations of the equipment operators.

[0044] The selection unit 314 selects equipment to cooperate in energy conservation according to predetermined rules. For example, the selection unit 314 selects equipment with high power consumption or equipment with a sudden increase in power consumption as equipment to cooperate in energy conservation. The selection unit 314 may register the amount of energy that can be saved for each piece of equipment and select equipment with a large amount of energy that can be saved as equipment to cooperate in energy conservation, prioritizing those equipment. The selection unit 314 may select equipment that has registered in advance that it will cooperate in energy conservation. The selection unit 314 may select the target equipment based on the facility energy information calculated by the energy supply destination facility 700. This allows the facility server device 300 to automatically select the target equipment from the facility energy information.

[0045] The equipment setting unit 316 sets setting change information for each energy supply destination facility 700, which includes multiple equipment operators, the settings target operated by each equipment operator, and the type of setting change for each setting target. The settings target operated by each equipment operator is, for example, air conditioning equipment, and the type of setting change for each setting target is, for example, the operating mode of the air conditioning equipment, the target temperature, etc.

[0046] The facility administrator terminal 400 includes, for example, a first notification unit 402, a second acquisition unit 404, a second notification control unit 406, a second target acquisition unit 408, and a second output control unit 410. The first notification unit 402, the second acquisition unit 404, the second notification control unit 406, the second target acquisition unit 408, and the second output control unit 410 are implemented, for example, by a computer such as a communication circuit and CPU executing a program stored in program memory.

[0047] The first notification unit 402 notifies the facility manager when it receives a facility cooperation notification from the EMS server device 200. The first notification unit 402 outputs, for example, a notification that it has received a facility cooperation notification via a display device or speaker. The second acquisition unit 404 acquires equipment operator information when requesting cooperation in saving electricity, and acquires equipment notification information for the energy supply destination facilities 700 managed by the facility manager indicated by the acquired equipment operator information. The equipment operator information is table data that associates information identifying the equipment included in the energy supply destination facility 700 with information identifying the equipment operator. The second notification control unit 406, based on the equipment notification destination information, causes at least one of the multiple equipment operators within the energy supply destination facility 700 to send an equipment cooperation notification requesting cooperation in saving electricity. The second output control unit 410 outputs a request screen that prompts the user to select at least one of several pieces of equipment based on the facility energy information calculated by the energy supply destination facility 700.

[0048] Figure 5 shows an example of a request screen presented to the facility manager of the energy supply recipient facility 700. As shown in Figure 5(a), the facility manager terminal 400 displays, for example, a facility cooperation notification and a cooperation request button within the facility. The facility cooperation notification includes information such as forecast information on electricity demand in the target area and information on energy saving measures. When the cooperation request button within the facility is selected, the facility administrator terminal 400 automatically sends an equipment cooperation notification requesting cooperation in saving electricity to at least one of the multiple equipment operators within the energy supply recipient facility 700. The facility administrator terminal 400 may display a cooperation selection screen as shown in Figure 5(b) when the cooperation request button within the facility is selected. The cooperation selection screen includes information showing a list of equipment and a cooperation request notification button. When the cooperation request notification button is selected, the facility administrator terminal 400 sends equipment cooperation notifications to one or more equipment selected in the list of target equipment. The second output control unit 410 can select at least one of several pieces of equipment based on the input on the request screen. The second notification control unit 406 can select at least one of several pieces of equipment based on the equipment notification destination information and send an equipment cooperation notification to the notification destination of the equipment operator of the selected piece of equipment.

[0049] The equipment operator terminal 500 includes, for example, a second notification unit 502, a third acquisition unit 504, a display control unit 506, a setting change unit 508, a setting information acquisition unit 510, and a reporting unit 512. The second notification unit 502, the third acquisition unit 504, the display control unit 506, the setting change unit 508, the setting information acquisition unit 510, and the reporting unit 512 are implemented, for example, by a computer such as a communication circuit or CPU executing a program stored in program memory. When the second notification unit 502 receives an equipment cooperation notification transmitted from the facility administrator terminal 400, it notifies the equipment operator. The second notification unit 502 outputs, for example, a message via a display device or speaker indicating that it has received the facility cooperation notification. The third acquisition unit 504 acquires equipment operator information indicating the equipment operator, and based on the setting change information, acquires setting target information indicating the setting targets operated by the equipment operator indicated by the acquired equipment operator information. As shown in Figure 6, the display control unit 506 displays the target to be set based on the target information, allowing selection of the target to be set, and displays the selected target according to the type of setting change.

[0050] Figure 6 shows an example of a request screen presented to the equipment operator in the embodiment. As shown in Figure 6(a), the equipment operator terminal 500 displays, for example, an equipment cooperation notification and a button for setting the equipment. The equipment cooperation notification includes, for example, information such as forecast information on power demand in the target area and information on energy saving measures. In response to the selection of the button for setting the equipment, the equipment operator terminal 500 may display the equipment operator screen as shown in Figure 6(b). The equipment operator screen includes information showing a list of equipment, equipment setting information such as a decrease in the set temperature, and a button for changing the settings. In response to the selection of the button for changing the settings, the equipment operator terminal 500 sends a request to the equipment to change the settings of one or more equipment selected in the list of target equipment.

[0051] As shown in Figure 6(b), the setting change unit 508 instructs the target to change its settings. The display control unit 506 displays an input field for entering the setting value after the setting change, and the setting change unit 508 can instruct the target to change its settings based on the setting value entered in the input field. The display control unit 506 may display multiple configurable targets for selection, as shown in Figure 6(b). The setting change unit 508 can instruct the selected multiple configurable targets to change their settings based on predetermined setting values ​​or setting values ​​entered in the input fields. As a result, when the equipment operator terminal 500 receives a request for cooperation in saving electricity, it can select multiple configurable targets, set setting values ​​for the selected multiple configurable targets, and instruct the setting change. This allows the equipment operator to respond to requests for cooperation in saving electricity. Furthermore, when a setting change is made, the setting information acquisition unit 510 may acquire the setting value information after the setting change for the setting target operated by the equipment operator indicated in the equipment operator information, based on the setting change information. The reporting unit 512 reports the acquired setting value information after the setting change to the facility manager predetermined for each equipment operator indicated in the equipment operator information. As a result, the equipment operator terminal 500 can notify the facility manager of the details of the setting change when the equipment operator changes the settings of the equipment. In this way, the facility manager can check the status of the equipment operator's response to the request for cooperation in saving electricity.

[0052] Figure 7 shows an example of the operation flow of the energy management system 1 in the embodiment. First, the input unit 302 of the facility server device 300 inputs the energy increase / decrease factors (step S100) and transmits information indicating the energy increase / decrease factors to the EMS server device 200. The EMS server device 200 continuously acquires energy information measured by the measurement unit 710 of the energy supply destination facility 700 and calculates area energy information (step S102). The EMS server device 200 transmits the calculated area energy information to the EMS administrator terminal 210. The EMS administrator terminal 210 notifies the administrator of the energy management system 1 of the received area energy information (step S104).

[0053] The facility server device 300 stores the energy increase / decrease factors for each energy supply destination facility 700 entered in step S100, and the increase / decrease values ​​of the facility energy information at that energy supply destination facility 700 in association with each other (step S106). This allows the facility server device 300 to accumulate the increase / decrease values ​​of the facility energy information when a particular energy increase / decrease factor occurs at each energy supply destination facility 700.

[0054] Subsequently, when the facility server device 300 receives energy increase / decrease factors via the input unit 302 (step S108), the search unit 306 searches for past increase / decrease values ​​of facility energy information (step S110). The facility server device 300 then transmits information indicating the energy increase / decrease factors, and information indicating the past increase / decrease values ​​of facility energy information found from those energy increase / decrease factors, to the EMS server device 200.

[0055] The EMS server device 200 calculates area energy information using the increase / decrease values ​​of past facility energy information received from the facility server device 300 (step S112), and transmits the calculated area energy information and information indicating the factors causing the energy increase / decrease to the EMS administrator terminal 210. This allows the EMS administrator terminal 210 to notify the administrator of the energy management system 1 of the factors causing the energy increase / decrease and the area energy information (step S114).

[0056] When the facility server device 300 receives energy increase / decrease factors and date / time information for when those factors occur via the input unit 302, it calculates a future predicted value of facility energy information when the energy increase / decrease factors occur at the date / time indicated by the date / time information (step S116). The facility server device 300 transmits the energy increase / decrease factors, date / time information, and the calculated future predicted value of facility energy information to the EMS server device 200. The EMS server device 200 calculates future area energy information at the date / time indicated by the date / time information based on the future predicted value of facility energy information (step S118) and transmits it to the EMS administrator terminal 210. This allows the EMS administrator terminal 210 to notify the administrator of the energy management system 1 of the future energy increase / decrease factors and future area energy information at the date / time indicated by the date / time information (step S120).

[0057] As described above, according to the energy management system 1 of this embodiment, when the facility server device 300 inputs energy increase / decrease factors that affect the facility energy information of an energy supply destination facility 700, it transmits information indicating the energy increase / decrease factors to the EMS server device 200, and the EMS server device 200 can calculate area energy information based on the energy increase / decrease factors. Thus, according to the energy management system 1, when various players participating in a regional EMS jointly utilize energy, when an energy increase / decrease factor is identified at a certain energy supply destination facility 700, the facility server device 300 transmits information indicating the energy increase / decrease factor, as well as information indicating the increase / decrease value of past facility energy information, to the EMS server device 200. Furthermore, by having the EMS server device 200 calculate future area energy information based on the energy increase / decrease factors and notify the administrator of the energy management system 1, the regional EMS can be operated smoothly while taking into account energy changes throughout the region.

[0058] Figure 8 shows another example of the operation flow of the energy management system 1 in the embodiment. The first notification destination setting unit 202 of the EMS server device 200 sets facility notification destination information for each energy supply destination facility 700 (step S200). The second notification destination setting unit 312 of the facility server device 300 sets facility notification destination information for multiple facility operators (step S202).

[0059] The area energy management device 100 predicts the balance between the energy supplied from the energy supply facility 600 to the energy recipient facility 700 and the energy demanded by the energy recipient facility 700 (step S204). At this time, the area energy management device 100 may use area energy information based on energy increase / decrease factors calculated by the EMS server device 200 to predict the balance between the energy supplied by the energy recipient facility 700 and the energy demanded by the energy recipient facility 700. If the energy demand does not exceed the energy supply (step S206: NO), the area energy management device 100 returns to step S102. For example, if the energy demand exceeds the energy supply, the area energy management device 100 determines whether to request a power saving (step S206: YES) and sends a power saving cooperation request to the EMS administrator terminal 210.

[0060] The EMS administrator terminal 210 obtains facility notification destination information from the EMS server device 200 (step S208), and, based on the obtained facility notification destination information, causes the first notification control unit 214 to send a facility cooperation notification as a first notification to at least one of the multiple energy supply destination facilities 700 (step S210), thereby sending the facility cooperation notification to the EMS server device 200. Upon receiving the facility cooperation notification, the EMS server device 200 sends the facility cooperation notification to the facility administrator terminal 400.

[0061] When the facility administrator terminal 400 receives a facility cooperation notification, it notifies the facility administrator via the first notification unit 402 (step S212). The facility administrator terminal 400 obtains equipment operator information and equipment notification destination information (step S214). Based on the equipment notification destination information, the second notification control unit 406 causes the facility server device 300 to send a facility cooperation notification as a second notification to at least one of the multiple equipment operators within the energy supply destination facility 700.

[0062] Upon receiving the facility cooperation notification, the facility server device 300 sends the facility cooperation notification to the facility operator terminal 500 (step S216). As a result, the facility operator terminal 500 notifies the facility operator of the power saving cooperation based on the facility cooperation notification. Furthermore, the facility operator terminal 500 may acquire facility operator information, acquire information to be configured, and display information according to the equipment to be configured and the type of configuration change.

[0063] As described above, according to the energy management system 1 of the embodiment, the EMS server device 200 sets facility notification information with notification destinations set for each energy supply destination facility 700, the facility server device 300 for each energy supply destination facility 700 sets equipment notification information with notification destinations set for multiple equipment operators, and when the area energy management device 100 predicts the balance between the energy supplied by the energy supply destination facility 700 and the energy demanded by the energy supply destination facility 700 using area energy information based on energy increase / decrease factors calculated by the EMS server device 200 and sends a power saving cooperation request to the EMS administrator terminal 210, the EMS administrator terminal 210 sends a facility cooperation notification to at least one notification destination of the multiple energy supply destination facilities 700 based on the facility notification information, the facility administrator terminal 400 notifies the facility administrator when it receives a facility cooperation notification, and sends an equipment cooperation notification to at least one notification destination of multiple equipment operators within the energy supply destination facility 700 based on the equipment notification information. As a result, the energy management system 1 enables a hierarchical notification structure, allowing for smooth operation of the regional EMS when, for example, the need for energy conservation arises in the regional EMS, and various players participating in the regional EMS share energy resources.
