Summary of the Invention

Problems to be Solved by the Invention

[0004] A regional Energy Management System (EMS) collects and stores energy-related data from multiple facilities that receive energy in a given region, using equipment within those facilities. Through data analysis, it supports energy management through prediction, optimal planning, and optimal control. In a regional EMS, the energy required for management in the region is not limited to electricity; it includes various types of energy such as fuel energy and thermal energy. The regional EMS must manage the supply of these various types of energy and supply energy from the equipment of each energy supply facility to the equipment of each energy recipient facility.

[0005] Regional Energy Management Systems (EMS) sometimes utilize "visualization," displaying usage data such as the consumption and decarbonization of various energy sources in numerical form. Meanwhile, with growing concern for environmental issues in recent years, efforts and results in energy conservation and decarbonization have significantly impacted the value and evaluation of the companies and other players involved in these efforts. These players include, for example, managers of energy supply facilities, managers of equipment at energy supply facilities, managers of facilities receiving energy supplies, and managers of equipment at facilities receiving energy supplies. If the results of these efforts can be rewarded to these players, their efforts will be further encouraged, environmental problems will be resolved more quickly, and a sustainable circular economy can be built.

[0006] However, the reality is that players in regional energy management systems (EMS), including not only the businesses that manage the entire EMS but also companies that manage the facilities included in the EMS, are not actively promoting their contributions to the environment, such as energy conservation and decarbonization.

[0007] This disclosure is made in light of these circumstances and aims to provide an energy management system, energy management method, and program that can disseminate information not only about the regional EMS as a whole, but also about the environmental contributions of the players in the facilities participating in the regional EMS.

[0021] Figure 3 is a block diagram showing an example of the energy management system 1 in the first embodiment. Although the functional components shown in Figure 3 are distributed as shown in Figure 3, they may be distributed or consolidated in other forms.

[0025] 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.

[0026] 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.

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.

[0028] The energy supply destination facilities 700 are customer facilities that consume the energy supplied from the energy supply facility 600. Energy supply destination facilities 700A include, for example, customer facilities such as factories and residences located in the target area. Energy supply destination facilities 700B include, 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 facility information calculation unit 210 calculates facility energy management information corresponding to each of the multiple energy supply destination facilities 700 based on the energy information measured at each of the energy supply destination facilities 700. The facility energy management information includes, for example, energy-related information for each energy supply destination facility 700, such as energy savings, CO2 reduction, energy consumption, energy reduction, total energy (energy generated - energy consumed), CO2 emissions, and CO2 reduction.

[0031] The area information calculation unit 220 calculates area energy management information corresponding to the target area based on multiple energy information from multiple energy supply facilities 700. Area energy management information includes, for example, energy-related information for the entire target area, such as energy savings, CO2 reduction, energy consumption, energy reduction, total energy (energy generated - energy consumed), CO2 emissions, and CO2 reduction.

[0032] The display information generation unit 230 generates display information that displays area energy management information in the first area and facility energy management information in the second area. Based on the display information, the output control unit 250 displays area energy management information in the first area and facility energy management information for at least one of the multiple energy supply destination facilities 700 in the second area.

[0033] Figure 4 shows an example of the information to be displayed on the display devices 300 and 310 in the first embodiment. The displayed information is, for example, information to be displayed in the first area as area energy management information, showing the total reduction amount of XX for the entire region (XX is any amount of energy such as CO2 or an indicator), and in the second area as facility energy management information, showing the reduction amount of XX for each energy supply destination facility 700. In addition, the displayed information may also show the reduction amount of XX when EMS is not introduced and the reduction amount of XX when thermal EMS is not introduced, near the first area, in order to represent the environmental contribution of the energy management system 1.

[0034] Figure 5 shows an example of the operation flow of the energy management system 1 in the first embodiment. First, the measurement unit 710 of the energy supply destination facility 700A measures energy information and transmits the measured energy information to the information management device 200 (step S100). The information management device 200 acquires energy information from the energy supply destination facility 700A. The facility information calculation unit 210 calculates facility energy management information for the energy supply destination facility 700A based on the energy information acquired from the measurement unit 710 (step S102). Also, the measurement unit 710 of the other energy supply destination facility 700B measures energy information and transmits the measured energy information to the information management device 200 (step S104). The information management device 200 acquires energy information from the energy supply destination facility 700B. The facility information calculation unit 210 calculates facility energy management information for the energy supply destination facility 700B based on the energy information acquired from the measurement unit 710 (step S106). The area information calculation unit 220 calculates area energy management information corresponding to the target area in the target area based on the facility energy management information of the energy supply destination facility 700A and the facility energy management information of the energy supply destination facility 700B (step S108). Next, the display information generation unit 230 generates display information that displays the area energy management information in the first area and the facility energy management information in the second area (step S110). Next, the output control unit 250 outputs the display information to the display devices 300 and 310 (step S112). As a result, the display devices 300 and 310 display the area energy management information in the first area and the facility energy management information of at least one of the multiple facilities in the second area based on the display information (step S114).

[0035] As described above, the energy management system 1 of the first embodiment can calculate facility energy management information based on energy information measured at each of the multiple energy supply destination facilities 700, calculate area energy management information based on the facility energy management information of the multiple energy supply destination facilities 700, display the area energy management information in the first area, and display the facility energy management information of at least one of the multiple energy supply destination facilities in the second area. As a result, the energy management system 1 can transmit not only information about the entire regional EMS, but also information about the players among the facilities participating in the regional EMS.

[0036] The facility selection unit 240 may select an energy supply facility 700 to be displayed from among multiple energy supply facilities 700. For example, if an energy supply facility 700 is selected based on the operation of a viewer using the display devices 300 and 310, the facility selection unit 240 selects the energy supply facility 700. The facility selection unit 240 may select an energy supply facility 700 based on facility energy management information. For example, the facility selection unit 240 may select an energy supply facility 700 that has a large CO2 reduction amount or an energy supply facility 700 that has a small amount of waste. The display information generation unit 230 generates display information for the selected energy supply facility 700 (step S110). The output control unit 250 outputs the facility energy management information of the selected target facility, thereby displaying the facility energy management information of the target facility on the display devices 300 and 310 (steps S112 and S114). As a result, the energy management system 1 can transmit information that includes area energy management information for the entire target area and facility energy management information for selected target facilities.

[0037] The facility information calculation unit 210 may calculate multiple facility energy management information for each energy supply destination facility 700, with different variables or units of variables (steps S102, S106). The variables are, for example, information specific to each energy supply destination facility 700, such as energy consumption, CO2 emissions, CO2 reduction amount, and waste amount. The units of the variables are, for example, CO2 reduction rate [%] and CO2 reduction amount [tons]. The information selection unit 242 selects some facility energy management information from multiple facility energy management information for the target facility. The display information generation unit 230 generates display information for the target facility to display the selected facility energy management information (step S110). The output control unit 250 displays the selected facility energy management information for the target facility on the display devices 300 and 310 (steps S112 and S114). As a result, the energy management system 1 can display the degree of contribution to the environment for each energy supply destination facility 700, viewed by variable, along with the area energy management information. Furthermore, the energy management system 1 can display the degree of contribution to the environment for each energy supply facility 700, in terms of each variable unit, along with area energy management information. In addition, the information management device 200 can select and display good facility energy management information for each energy supply facility 700.

[0038] The measurement unit 710 measures energy information for each tenant facility of the energy supply destination facility 700 and outputs it to the information management device 200. The facility information calculation unit 210 calculates facility energy management information, including energy management information for each tenant facility. Energy management information for each tenant facility includes, for example, energy consumption, CO2 reduction amount, and waste amount for each tenant facility. The display information generation unit 230 may generate display information for building tenant services, which is transmitted to building tenants located in the target facility, based on the energy management information for each tenant facility (step S110). Display information for building tenant services is, for example, if the energy supply destination facility 700 is a commercial building and an apparel shop located in the commercial building provides an online mail-order service, the display information is for displaying the apparel shop's energy management information via the online mail-order service. The output control unit 250 causes the building tenants to display the information using the building tenant service (step S112). As a result, the energy management system 1 can display energy management information for the facilities of the energy supply destination facility 700, along with area energy management information.

[0039] (Second Embodiment) Figure 6 is a block diagram showing an example of the information management device 200A in the second embodiment. The information management device 200A of the energy management system 1 in the second embodiment differs from that of the first embodiment in that it includes an energy analysis unit 260 and a policy selection unit 262. In the second embodiment, the area information calculation unit 220 collects facility energy consumption information from the energy information of multiple energy supply destination facilities 700. The facility energy consumption information is energy information for each piece of equipment within the facility, such as lighting equipment, air conditioning equipment, ventilation equipment, hot water supply equipment, and elevator equipment, and indicates the content of the energy consumed by the equipment within the facility.

[0040] The energy analysis unit 260 analyzes the energy consumption trends for each target facility from facility energy consumption information. Energy consumption trends include, for example, changes in energy consumption per piece of equipment over time, changes in energy consumption per piece of equipment over day of the week, and changes in energy consumption per piece of equipment over season. The policy selection unit 262 selects energy reduction measures that have been registered in advance according to the energy consumption trends for each target facility. The display information generation unit 230 generates display information to display the selected energy reduction measures, and the output control unit 250 outputs the display information to display the energy reduction measures selected by the policy selection unit 262 to the display devices 300, 310, or the user terminal device 400.

[0041] The information management device 200A displays area energy management information in the first area and facility energy management information in the second area, and also allows facility managers, equipment managers, and other users to view energy reduction measures. As a result, the energy management system 1 in the second embodiment can communicate the efforts of facility players participating in the regional EMS by displaying energy reduction measures for area energy management information and facility energy management information.

[0042] (Third embodiment) Figure 7 is a block diagram showing an example of the information management device 200B in the third embodiment. The information management device 200B of the energy management system 1 in the third embodiment differs from the second embodiment in that it includes a reduction target calculation unit 270, an energy reduction achievement determination unit 272, and a reward calculation unit 274.

[0043] The reduction target calculation unit 270 calculates an energy reduction target from the energy consumption trends analyzed by the energy analysis unit 260. The reduction target calculation unit 270 identifies the energy consumption content to be reduced from among the energy consumption content of multiple pieces of equipment included in the energy supply destination facility 700. The reduction target calculation unit 270 may, for example, identify the energy consumption content to be reduced based on information obtained from the manager of the energy supply destination facility 700, or it may identify the energy consumption content to be reduced based on the time of day or season. The reduction target calculation unit 270 calculates an area energy reduction target from the area energy management information, and calculates a facility energy reduction target from the area energy reduction target for each target facility. The display information generation unit 230 generates display information to display the selected facility energy reduction target for each target facility. The output control unit 250 outputs the display information to the display devices 300 and 310 to display the selected facility energy reduction target for each target facility.

[0044] The energy reduction achievement determination unit 272 determines the energy reduction achievement status for each target facility based on the difference between the facility's energy reduction target and the energy consumption information from the facility's energy management data. The reward calculation unit 274 calculates the energy reduction reward for each target facility based on the energy reduction achievement status and predetermined conditions. For example, predetermined conditions may include a budget, point conversion rate, and coupon issuance conditions, and the energy reduction reward may be money, points, or coupons.

[0045] The information management device 200B displays area energy management information in the first area and facility energy management information in the second area, and also allows facility managers, equipment managers, and other users to view facility energy reduction targets. As a result, the energy management system 1 in the third embodiment can communicate the progress of facility players participating in the regional EMS by displaying facility energy reduction targets for each target facility. Furthermore, the information management device 200B can determine the energy reduction achievement status for each target facility and calculate an energy reduction reward based on predetermined conditions derived from the energy reduction achievement status. As a result, the energy management system 1 in the third embodiment can realize a mechanism to reward the efforts of players in the regional EMS for their achievements.

[0046] Although various embodiments and modifications have been described, these are merely examples and are not limited to these.
