[0004] [Patent Document 1] JP 2022-120506 A Summary of the Invention [Problem to be solved by the invention]

[0005] Conventional technologies place emphasis on reducing the costs of power transmission and distribution companies that own distribution facilities, such as by expanding their facilities, and on reducing the costs of consumers installing storage batteries. However, if a business uses distributed power sources to supplement the electricity required for business operations, it is necessary to maintain existing operations. Furthermore, when multiple businesses jointly introduce and use distributed power sources, problems such as increased investment costs and reduced CO2 emission reduction effects may arise because each business has different circumstances. The present invention aims to provide a planning device, planning method, and planning system that can develop a plan for the introduction of distributed power sources taking into account the circumstances of each business operator while ensuring the maintenance of existing operations when multiple business operators jointly introduce and use distributed power sources. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention provides a planning device including an acquisition unit that acquires information on resources required when multiple business operators introduce distributed power sources, and a planning unit that creates a distributed power source introduction plan based on the resource information so that the resources allocated to each business operator satisfy a predetermined target value and the power used by each business operator can be secured. In this case, when multiple business operators jointly introduce and use distributed power sources, a planning device can be provided that can create a distributed power source introduction plan taking into account the circumstances of each business operator while ensuring the maintenance of conventional operations.

[0007] Here, the planning unit can create a distributed power source introduction plan by finding an optimal solution of an objective function that represents resources based on a constraint condition that represents a target value. In this case, it becomes easier to create a distributed power source introduction plan. In addition, the planning unit can further add a constraint indicating that each business operator can secure the power they need to use, and can plan the introduction of distributed power sources. In this case, it is possible to ensure that conventional operations can be maintained. Furthermore, the planning unit can further add constraints necessary for operating a vehicle that uses power from the distributed power source and create a vehicle operation plan. In this case, when a vehicle is introduced as a distributed power source, the planning unit can also create a vehicle operation plan. Furthermore, the planning unit can calculate the time it takes for the vehicles of the multiple operators to travel to their destinations for each time period, and calculate the allocation of the vehicles to their destinations for each time period so that the travel times of the vehicles of the multiple operators in all time periods satisfy a certain threshold. In this case, the allocation of the vehicles to their destinations for each time period can be more accurately performed. The acquisition unit can also acquire items that the business operator considers important when introducing distributed power sources, and the planning unit can reflect the items that the business operator considers important as weights for decision variables in the objective function. In this case, a distributed power source introduction plan can be created that meets the business operator's wishes. Furthermore, the decision variables can include the total cost of introducing distributed power sources, the total amount of CO2 reduction when the distributed power sources are introduced, and the total distance traveled by vehicles when they are introduced as distributed power sources. In this case, a more appropriate objective function can be used to plan the introduction of distributed power sources. Furthermore, the plan formulation unit may further formulate an introduction plan in which the location of the distributed power sources is changed in relation to the introduction plan formulated by finding the optimal solution. In this case, a better solution to the objective function may be found. The planning unit can then compare the introduction plan created by finding the optimal solution with an introduction plan in which the placement of the distributed power sources is changed, and create a final introduction plan. In this case, a better introduction plan for the distributed power sources can be created. The resources can also include the area available for installation of distributed power sources, the investment cost required for introducing distributed power sources, and the amount of CO2 reduction resulting from the introduction of distributed power sources. In this case, the items that are particularly necessary when introducing distributed power sources can be used to plan the introduction of distributed power sources. Furthermore, a display information creation unit is provided that creates display information for displaying the drawn up plan, and the display information can include information on resources allocated to the business operator to support the decision-making of the distributed power introduction plan. In this case, the business operator can easily determine the validity of the drawn up plan. Furthermore, the display information can be information that indicates the relative merits of distributed energy introduction plans and vehicle operation plans based on investment costs, CO2 reductions, and vehicle travel times, as desired by multiple business operators. In this case, information that is likely to be a burden for business operators can be presented.

[0008] The present invention also provides a planning method in which a processor executes a program recorded in a memory to obtain information about resources required when multiple business operators introduce distributed power sources, and to create a plan for introducing distributed power sources based on the information about resources so that the resources allocated to each business operator satisfy a predetermined target value and the power used by each business operator can be secured.When multiple business operators jointly introduce and use distributed power sources, a planning method can be provided that can create a plan for introducing distributed power sources while taking into account the circumstances of each business operator while ensuring the maintenance of conventional operations.

[0009] Furthermore, the present invention is a planning system that includes a planning device that plans an introduction plan for distributed power sources when multiple business operators introduce distributed power sources, and a terminal device that sends information necessary for planning the introduction plan to the planning device, and the planning device includes an acquisition unit that acquires information regarding resources required when the multiple business operators introduce distributed power sources, and a planning unit that plans an introduction plan based on the information regarding the resources so that the resources allocated to each business operator satisfy a predetermined target value and the power used by each business operator can be secured. In this case, when multiple business operators jointly introduce and use distributed power sources, a planning system can be provided that can plan an introduction plan for distributed power sources while taking into account the circumstances of each business operator while ensuring the maintenance of conventional operations. Effect of the Invention

[0010] According to the present invention, when multiple business operators jointly introduce and use distributed power sources, it is possible to provide a planning device, planning method, and planning system that can develop a plan for the introduction of distributed power sources taking into account the circumstances of each business operator while ensuring the maintenance of existing operations.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] An embodiment of the planning system 1 will be described in detail below with reference to the drawings. In the following description, the same or similar components may be given common reference numerals and duplicated descriptions may be omitted. When there are multiple elements having the same or similar functions, different suffixes may be added to the same reference numerals. When there is no need to distinguish between multiple elements, the suffixes may be omitted.

[0013] <Outline of Planning System 1> The planning system 1 of this embodiment plans when multiple business operators jointly introduce distributed power sources. In this case, the business operators are not particularly limited, but may be, for example, building operators and bus operators. In the following, these business operators may be referred to as planners. The distributed power sources are made up of a plurality of power sources owned by each of a plurality of business operators, and are, for example, storage batteries, solar power generation, and charging stations. The number of distributed power sources owned by each business operator is not limited to one, and may be multiple. Each business operator uses the distributed power sources to execute conventional operations. In addition, in the planning system 1 of this embodiment, the distributed power sources include vehicles. That is, the vehicles are equipped with storage batteries themselves, and operate by driving a power source such as a motor with the power generated by the storage batteries. The vehicles are, for example, electric vehicles (EVs) and plug-in hybrid vehicles (PHVs). The storage batteries installed in the vehicles are charged with power from distributed power sources such as charging stations.

[0014] In this embodiment, the planning system 1 plans the introduction of distributed power sources that improves environmental value while maintaining the conventional business operations of each business operator, as described in detail below. In other words, as described above, each business operator uses distributed power sources, but at the same time, the system ensures that each business operator can secure the power they need to maintain their business operations. Furthermore, the planning system 1 creates a distributed power source introduction plan taking into consideration the circumstances of each business operator. Specifically, the planning system 1 creates a distributed power source introduction plan while complying with the area available for installing distributed power sources, investment costs, and CO2 reduction targets of each business operator. The distributed power source introduction plan is, for example, a plan to install storage batteries, solar power generation, and charging stations as distributed power sources. Also, it is a plan to introduce vehicles such as EVs as distributed power sources. Furthermore, the planning system 1 creates a vehicle operation plan. In this case, the planning system 1 has a display device and can display the advantages and disadvantages of each of the multiple introduction plans. In this case, multiple business operators can make decisions about introducing distributed energy sources based on the presented plans and their advantages and disadvantages. Multiple introduction plans can be created by changing values ​​such as the available area for installing power sources, investment costs, and CO2 reduction targets when registering these values.

[0015] <Explanation of the overall configuration of planning system 1> FIG. 1 is a block diagram showing an example of the overall configuration of a planning system 1 according to the present embodiment. In the planning system 1, an introduction / operation planning system 100 is connected to user terminals 113 and 116 used by planners (bus companies, building companies, etc.) via networks 114 and 115.

[0016] The user terminals 113 and 116 function as terminal devices that send information necessary for planning the introduction of distributed power sources to the introduction and operation plan planning system 100. In addition, the user terminals 113 and 116 function as terminal devices that are used when displaying the drawn up introduction plan for distributed power sources.

[0017] The networks 114, 115 are the Internet, a LAN (Local Area Network), or a WAN (Wide Area Network). The communication lines used for the networks 114, 115 may be wired or wireless. They may also be used in combination. Furthermore, the introduction and operation plan formulation system 100 and the user terminals 113, 116 may be connected via multiple networks or communication lines using relay devices such as gateway devices or routers.

[0020] The distributed power introduction plan formulation unit 103 is an example of a plan formulation unit, and formulates a plan for the introduction of distributed power sources. In this case, the distributed power introduction plan formulation unit 103 formulates a plan for the introduction of distributed power sources based on information about resources so that resources allocated to each business operator meet a predetermined target value and power to be used by each business operator can be secured. The resources are those necessary to introduce a distributed power source, such as the area and cost required to introduce the distributed power source, and the amount of CO2 reduction that can be achieved when the distributed power source is introduced. More specifically, in this embodiment, the resources include the area available for installing the distributed power source (the maximum area that can be provided when installing the distributed power source), the investment cost required to introduce the distributed power source (the maximum cost that can be borne when introducing the distributed power source), and the amount of CO2 reduction that occurs by introducing the distributed power source. The distributed power source introduction plan formulation unit 103 formulates an introduction plan for distributed power sources based on the information presentation and acquisition unit 105 , user and facility data 106 , facility power data 107 , and distributed power source data 110 .

[0021] The operation planning unit 104 is also an example of a planning unit, and creates an operation plan for the vehicle. The operation planning unit 104 creates an operation plan for the vehicle based on the existing vehicle data 108 and the destination data 109.

[0022] The information presentation and acquisition unit 105 is an example of an acquisition unit, and acquires information about resources required when a plurality of business operators introduce distributed power sources. The information presentation and acquisition unit 105 is an example of a display information creation unit, and creates display information for displaying the drawn up plans. That is, the information presentation and acquisition unit 105 creates display information for displaying the advantages and disadvantages of each of a plurality of plans on a display device.

[0023] The introduction and operation planning system 100 is realized by using a general PC (Personal Computer) or server. The user terminals 113, 116 used by planners (bus operators, building operators, etc.) are not limited to any particular electronic terminal that can be managed and can send and receive input information, and may be a general PC, tablet terminal, smartphone, etc.

[0024] That is, the introduction and operation planning system 100 and the user terminals 113 and 116 are computer devices, and have a processor such as a CPU (Central Processing Unit) that controls each part through the execution of a program, and a memory such as a RAM (Random Access Memory), a ROM (Read Only Memory), and a storage in which system data and internal data are stored. In addition, the introduction and operation planning system 100 and the user terminals 113 and 116 have a display device such as a display that displays images and other information. Furthermore, the introduction and operation planning system 100 and the user terminals 113 and 116 have input devices such as a keyboard and a mouse for inputting characters, etc. Note that the display device and the input device may be a touch panel that has both of these functions. Furthermore, the introduction and operation planning system 100 and the user terminals 113 and 116 have a communication interface used for communication with an external device.

[0025] <Outline of the operation of the planning system 1> In this embodiment, a planner (such as a bus operator or a building operator) accesses the introduction and operation planning system 100 using the user terminals 113 and 116, and uses various data held by the introduction and operation planning system 100 to plan an introduction and operation plan for distributed power sources for facilities owned by the planner. The planner then registers facilities for which multiple operators plan introduction plans for distributed power sources and vehicle operation plans, information about the facilities, information about the power required at the facilities, information about existing vehicles, and information about the distributed power sources to be introduced. The introduction and operation planning system 100 plans an introduction and operation plan that improves environmental value while maintaining conventional operations, while complying with the target values ​​for the area available for installing distributed power sources, investment costs, and CO2 reduction amounts for the facilities of multiple operators. In this embodiment, storage batteries, solar power generation, charging stations, and electric vehicles such as EVs and PHVs are given as examples of distributed power sources, but the actual types of distributed power sources are not limited to these. Furthermore, in this embodiment, devices necessary for operating distributed power sources are also treated as distributed power sources.

[0026] The introduction and operation plan formulation system 100 uses each registered information to formulate an introduction and operation plan that takes into consideration the maintenance of the planner's conventional business and the improvement of environmental value. The investment cost, environmental value, and vehicle operation time for conventional business are determined at the time of formulating the introduction and operation plan, and the formulated multiple plans, their advantages and disadvantages, and details of the operation plan and distributed energy introduction plan are displayed on the user terminals 113 and 116 of the business operators (bus operators, building operators, etc.).

[0034] <How to create a plan for introducing distributed power sources and a vehicle operation plan> Next, a specific method for creating a distributed power source introduction plan and a vehicle operation plan will be described. FIG. 9 is a sequence diagram showing a method for creating a distributed power source introduction plan and a vehicle operation plan. Hereinafter, specific processing of the introduction and operation planning system 100 will be described mainly with reference to FIG. 9. FIG. 9 shows a flow in which the planner uses the introduction and operation planning system 100, and the planner accesses the introduction and operation planning system 100 via the networks 114 and 115 using the user terminal 113 of FIG. 1. In this embodiment, the planners are the bus operator and the building operator, but the planners are not limited to these operators and may include local governments and non-profit organizations. Furthermore, in this embodiment, the planners are two operators, but the number of planners is not limited to two operators, and there is no limit to the number of operators that cooperate with each other.

[0035] First, the planner inputs and registers the user and facility data 106 (S901). The user and facility data 106 is registered by the introduction and operation plan making system 100 managing the facility data (S902). The input data includes, as shown in FIG. 2, a user ID 201, a facility ID 202, a facility name 203, a location (address) 204, an industry and facility type 205, an investment cost (M yen) 206, a contracted power (A) 207, an average daily power consumption (kWh) 208, a CO2 emission amount 209, a CO2 reduction target value 210, a facility area (m 2 )211, area where distributed power generation can be installed (m 2 ) 212 are stored in the user and facility data 106 in FIG.

[0036] Next, the planner inputs and registers the facility power data 107 (S903). The facility power data 107 is registered by the introduction and operation plan making system 100 managing the power data (S904). The input data includes, as shown in FIG. 3, the equipment 301, the power consumption (kW) per unit 302, the number of units required per area (units / 100m), etc. 2 1. The facility power data 107 in FIG. 1 is stored by items such as the power consumption (kW) 303 and the usage time per day (h / day) 304.

[0037] The planner also inputs and registers the existing vehicle data 108 (S905). The registration of the existing vehicle data 108 is performed by the introduction and operation plan making system 100 managing the vehicle data (S906). The input data is stored in the existing vehicle data 108 in Fig. 1 by items such as vehicle ID 401, fuel efficiency (km) 402, and usage time (h / day) 403, as shown in Fig. 4.

[0038] Furthermore, the planner inputs and registers destination data 109 (S907). The destination data 109 is registered by the introduction and operation planning system 100 managing the destination data (S908). The input data is stored in the destination data 109 in Fig. 1 by items, such as destination ID 501, destination address 502, location 503, designated arrival time 504, and designated departure time 505, as shown in Fig. 5.

[0039] Furthermore, the planner inputs and registers the distributed power source data 110 (S909). The distributed power source data 110 is implemented by the introduction and operation plan planning system 100 performing distributed power source data management (S910). The input data includes, as shown in FIG. 6, a resource ID 601, a resource name 602, a price (M yen) 603, and a required installation area (m 2 1 for each of the following items: power output (kW) 604, output (kW) 605, capacity (kWh) 606, power generation efficiency (kWh) 607, fuel consumption (km) 608, and minimum capacity (kWh) 609.

[0040] It is assumed that the registration of user / facility data 106 (S901), the registration of facility power data 107 (S903), the registration of existing vehicle data 108 (S905), the registration of destination data 109 (S907), and the registration of distributed power source data 110 (S909) are performed simultaneously by the planner, but this is not limited and the registration may be performed at different times. Furthermore, these registrations do not have to be performed in the above-mentioned order, and the order may be arbitrary. Various registrations are performed by the planner by accessing the operation planning system 100 using the user terminals 113 and 116.

[0041] Next, the introduction and operation plan formulation system 100 formulates an introduction plan for the distributed power sources and an operation plan for the vehicles (S911). Then, the introduction and operation plan formulation system 100 notifies the planner of the formulated plan (S912). The planner checks the plan he has prepared and makes a decision on whether or not to introduce distributed power sources (S913).

[0042] In this embodiment, the distributed power source introduction plan formulation unit 103 and the operation plan formulation unit 104 of the introduction and operation plan formulation system 100 formulate a distributed power source introduction plan and a vehicle operation plan that maximize the amount of reduction in the distributed power source introduction and maintenance costs, the amount of CO2 emissions reduction, and the reduction in vehicle travel time by sharing storage batteries, charging stations, etc. To this end, the introduction and operation plan formulation system 100 solves an optimization problem with the following formula 1 as the objective function.

[0043]

number

[0044] Σ a Σ d (x a,d *(introduce a,d )) is the total introduction cost of distributed power source d for facility a. x a,d is a flag indicating whether or not to allocate the distributed power source d to the facility a.

For example, when a business operator places importance on reducing the introduction cost of distributed power sources, the weight w1 is set to the largest value. The formula in equation 1 is Σ a Σ d (x a,d *(introduce a,d )), Σ a Σ d (x a,d *(aemission a,d - bemission a,d )), Σ e Σ t Σ i (y e,t,i *adistance e ) are decision variables, and equation (1) is the equation that maximizes them.

[0070] FIG. 10 is a flowchart illustrating a process for approximately solving the optimization problem of Equation 1. FIG. 10 is a flow of processing actually performed by the distributed power source introduction plan formulation unit 103 and the operation plan formulation unit 104 of the introduction and operation plan formulation system 100. First, the introduction and operation plan formulation system 100 reads the existing vehicle data 108, and further reads the distributed power source data 110, and calculates the number of vehicles (EVs) required to replace the existing vehicles (S1001). The calculated number of required vehicles (EVs) is stored in the resource ID 803 of the distributed energy introduction plan result data 112, and at that time the battery capacity (kWh) 808, minimum capacity (kWh) 800, and fuel efficiency (km) 810 are determined at the same time.

[0071] Next, the introduction and operation plan formulation system 100 calculates the amount of electricity required to operate the vehicle (EV) from the usage time (h / day) 403 of the existing vehicle data 108 and the fuel efficiency (km) 810 of the distributed energy introduction plan result data 112 (S1002). The introduction and operation plan formulation system 100 adds the amount of electricity required for operating the vehicle (EV) calculated in S1002 to the amount of electricity used in the facility of the business operator, and calculates the amount of electricity required for the facility (S1003). The introduction and operation plan making system 100 reads the user and facility data 106, the facility power data 107, the existing vehicle data 108, the destination data 109, and the distributed power source data 110, and creates an introduction plan for the distributed power source and an operation plan for the vehicle (EV) based on the amount of power required for the facility and the area where the distributed power source can be installed calculated in S1003 (S1004). In this case, the objective function of the above-mentioned formula 1 and the constraint conditions of formulas 2 to 8 are set, and the optimization problem is solved to create the introduction plan for the distributed power source and the operation plan for the vehicle.

[0072] After creating a distributed power introduction plan and a vehicle operation plan, the introduction and operation plan creation system 100 rearranges the locations of the distributed power sources (S1005). The rearrangement of the distributed power sources is performed by randomly determining the distributed power sources to be replaced and partially searching for x a,d This can be obtained by switching the distributed power source to 1 / 0.

[0073] The introduction and operation planning system 100 checks whether the introduction cost, CO2 emissions, and vehicle (EV) operation time of the distributed energy source (including EV) replaced by the replacement are updated (S1006). At this time, the introduction cost, CO2 emissions, and EV operation time may or may not have been improved.

[0074] The introduction and operation plan formulation system 100 compares the introduction cost, CO2 emissions, and EV operation time after the replacement of the distributed energy source with those before the replacement (S1007). As a result, if these values ​​are higher than those before the replacement or are the same (No in S1007), the process flow is repeated again from the replacement of the distributed power source (S1005). An arbitrary number of repetitions is preset. Here, this number is set to N times, and the introduction and operation plan formulation system 100 determines whether or not the process has been repeated N times (S1008). If it has not been repeated N times (No in S1008), the process returns to S1005.

[0075] Also, if these are lower than the values before the swap in S1007 (Yes in S1007), and if it has been repeated N times in S1008 (Yes in S1008), the solution that becomes the introduction of the distributed power source after the distributed power source swap (S1005) becomes the approximate solution of Equation (1), and is adopted as the introduction plan of the distributed power source and the operation plan of the vehicle (S1009). The formulated vehicle operation plan is stored in the operation plan result data 111 of FIG. 7. On the other hand, the formulated distributed power source introduction plan is stored in the distributed power source introduction plan result data 112 of FIG. 8.

[0076] In the form described above, as explained in S1004, the distributed power source introduction plan formulation unit 103 formulates the introduction plan of the distributed power source by obtaining the optimal solution of the objective function representing the resources based on the constraint conditions representing the target values. At this time, the distributed power source introduction plan formulation unit 103 further adds a constraint condition (Equation (8) above) representing that the power used by each operator can be ensured, and formulates the introduction plan of the distributed power source. Further, as explained in S1004, the operation plan formulation unit 104 further adds the constraint conditions (Equations (5) to (7) above) necessary to operate the vehicles using the power of the distributed power source, and formulates the operation plan of the vehicle. Thereby, for example, the distributed power source introduction plan formulation unit 103 can calculate the travel time when the vehicles of a plurality of operators move to the destination for each time period, and calculate the allocation of the vehicles to the destination for each time period so that the travel times of the vehicles of the plurality of operators satisfy a certain threshold value in all time periods. Also, as explained in S1005 to S1009, the distributed power source introduction plan formulation unit 103 and the operation plan formulation unit 104 compare the introduction plan formulated by obtaining the optimal solution with the introduction plan in which the arrangement of the distributed power source is swapped, and formulate the final introduction plan.

[0077] <Description of <UI (User Interface)>> FIG. 11 is an image diagram of the user interface when the planner inputs various data. A display screen 1101 shows an overall picture of the user interface. The planner inputs necessary items in an input field 1102, and if necessary, adds each item and inputs data.

[0081] Conventional inventions can introduce storage batteries that reduce the load on distribution facilities, but they place emphasis on reducing the costs of equipment expansion for the power transmission and distribution business operators who own the distribution facilities, and the cost of introducing storage batteries for consumers. However, when consumers who introduce distributed power sources such as storage batteries use distributed power sources to supplement the power required for their business, it is essential to maintain their conventional business. Furthermore, as distributed power sources become more widespread, it is possible for neighboring businesses to introduce distributed power sources and use them jointly. For example, when multiple bus businesses and building businesses in the same area jointly introduce EVs as storage batteries or business vehicles, the area, investment costs, and target CO2 reduction amounts of the businesses are different. Therefore, when distributed power sources are introduced according to individual circumstances, there is a possibility that the investment costs will increase and the effect of reducing CO2 emissions will be reduced because the area and investment amount cannot be flexible. In such cases, if multiple businesses can share the investment costs and the area available for installing distributed power sources, it is possible to reduce investment costs and increase the amount of CO2 reduction. Furthermore, by showing the proposed introduction plan for distributed power sources to multiple businesses, including the advantages and disadvantages, it is possible to support their decision-making on introducing distributed power sources.

[0082] Therefore, in this embodiment, the distributed power sources are shared among the businesses while satisfying the degree of sufficiency of the required amount of power that allows conventional operations, taking into consideration the area where the distributed power sources can be installed, the investment costs, and the target amount of CO2 reduction of the multiple businesses. Also, by sharing the distributed power sources among the businesses so as not to exceed the upper limit of the costs of the businesses, it is possible to formulate a distributed power source introduction plan and a vehicle operation plan that maximize the amount of reduction in the distributed power source introduction and maintenance management costs and the amount of CO2 emission reduction.

[0083] <Explanation of planning method> The processes performed by the introduction and operation planning system 100 are realized by the cooperation of software and hardware resources. That is, a processor in a computer provided in the introduction and operation planning system 100 loads a program for realizing each of the above-mentioned functions into memory, executes the program, and realizes each of the above-mentioned functions.

[0084] Therefore, the processing performed by the introduction and operation planning system 100 can be considered as a planning method in which a processor executes a program recorded in memory to obtain information regarding the resources required when multiple business operators introduce distributed power sources, and a plan for introducing distributed power sources is developed based on the resource information so that the resources allocated to each business operator meet predetermined target values ​​and the electricity used by each business operator can be secured.
