[Technical field]

[0001] The present disclosure relates to an energy trading management server and a mobile energy trading processing device. [Background technology]

[0002] JP 2020-186951 A (Patent Document 1) discloses an information providing device that includes a search unit that searches for whether or not there is a charging facility capable of charging the electric vehicle at a destination of the electric vehicle that is set based on an input operation by a user of the electric vehicle, and a providing unit that changes the route that the electric vehicle takes to travel to the destination depending on the presence or absence of a charging facility and provides this to the user of the electric vehicle.

[0003] [Patent Document 1] JP 2020-186951 A Summary of the Invention [Problem to be solved by the invention]

[0004] Due to the liberalization of the electricity market, the introduction of P2P (Peer to Peer) electricity trading, in which electricity is traded directly between not only electric power companies but also individuals or corporations who own electricity resources and other individuals or corporations who are electricity consumers, is being considered. In P2P electricity trading, by using mobile objects such as electric vehicles equipped with large-capacity storage batteries as a means of storing electricity, ordinary individuals or corporations can trade electricity using the mobile objects.

[0005] When P2P energy trading using mobile objects is performed, the market can be categorized into a "general trading market" and an "individual trading market." The "general trading market" is a market in which an agreement is made for electricity to be procured from an electricity seller to a buyer via a transmission line of a power grid. The "individual trading market" is a market in which an agreement is made for electricity to be directly exchanged between one party and another party by moving the mobile object to the other party's location. For mobile objects, being able to procure electricity to charge a storage battery through the individual trading market is very useful in reducing electricity costs. For example, as in Patent Document 1, by providing the owner of the mobile object with information on charging facilities as a stopover on the way to the destination, it becomes possible to procure electricity while traveling to the destination, thereby reducing the cost and effort required for procuring electricity for the mobile object.

[0006] However, in Patent Document 1, mobile unit owners are only provided with location information of charging facilities, and are not provided with information on electricity trading. Therefore, in order to realize electricity procurement through the individual trading market, it is necessary to build a system that allows mobile unit owners to obtain information on the individual trading market that is advantageous to them.

[0007] The present disclosure has been made to solve such problems, and an objective of the present disclosure is to provide mobile entities with information regarding energy transactions being bid in the individual trading market in P2P energy trading, so that the mobile entities can participate in energy transactions on favorable terms. [Means for solving the problem]

[0008] An energy trading management server according to an aspect of the present disclosure manages trading of electricity in an energy trading market. The energy trading market includes a plurality of individual trading markets provided corresponding to a plurality of charging / discharging facilities, respectively. Each of the plurality of individual trading markets is configured to contract trading of electricity directly exchanged between a corresponding charging / discharging facility and a mobile object. The energy trading management server includes a storage device, a registration unit, an input unit, a setting unit, a search unit, and a presentation unit. The registration unit receives, for each individual trading market, energy trading information including location information of the corresponding charging / discharging facility and bidding conditions for trading electricity, and registers the information in the storage device. The input unit receives information of the mobile object participating in the energy trading market. The information of the mobile object includes information indicating a geographical range in which the mobile object can exchange electricity. The setting unit sets a search condition based on the information of the mobile object. The search unit searches for an individual trading market that matches the search condition among the plurality of individual trading markets. The presentation unit presents energy trading information in the individual trading market that matches the search condition.

[0009] According to the above configuration, the energy trading management server presents energy trading information in the individual trading market for charging / discharging facilities that exist within a geographical range where a mobile unit can receive and send energy, so that an energy trading processing device for a mobile unit (hereinafter also referred to as a "mobile unit agent") that performs bidding and agreements for a mobile unit can efficiently collect energy trading information in the individual trading market for which the mobile unit can bid. In addition, the mobile unit agent can determine bidding conditions for the mobile unit's energy trading while referring to the presented energy trading information in the individual trading market, so that the mobile unit can participate in energy trading under favorable conditions.

[0010] Preferably, the bidding conditions include a time period during which the corresponding charging / discharging facility is available to receive and transmit power, and a buying / selling price for each unit time period in the time period. Preferably, the bidding conditions further include an amount of power for each unit time period in the time period.

[0011] According to this, the mobile agent can determine bidding conditions for the power trading in the mobile unit based on the presented bidding conditions, thereby enabling the mobile unit to participate in the power trading under favorable conditions.

[0012] Preferably, the information about the mobile object includes information about a current location of the mobile object. The setting unit sets, as the search condition, a geographical range defined based on the current location of the mobile object.

[0013] With this, electricity trading information about charging / discharging facilities located within a specified range based on the current location of the mobile body is presented, and the mobile body agent can determine the bidding conditions using the presented electricity trading information while referring to the future usage status of the mobile body so as to maximize the profits in electricity trading within the range of the amount of electricity that the mobile body's storage battery can charge and discharge.

[0014] Preferably, the information about the mobile object includes information about a region that is a living area of ​​an owner of the mobile object. The setting unit sets a geographical range including the region that corresponds to the living area as the search condition.

[0015] With this system, electricity trading information about charging / discharging facilities located within the living area of ​​the mobile body owner is presented, and the mobile body agent can use the presented electricity trading information to determine bidding conditions so as to maximize profits in electricity trading within the range of the amount of electricity that the mobile body's storage battery can charge and discharge, while referring to the future usage status of the mobile body.

[0016] Preferably, the information about the mobile object includes information about a travel route from a current position of the mobile object to a destination point. The setting unit sets, as the search condition, a geographical range that is determined so as to include the travel route.

[0017] With this, electricity trading information about charging and discharging facilities located in the vicinity of the driving route to the destination is presented, so that the mobile agent can determine the bidding conditions using the presented electricity trading information so as to maximize the profits in electricity trading, without significantly changing the driving route to the destination and the arrival time at the destination, even if it is predicted that the storage battery will need to be charged before reaching the destination.

[0018] Preferably, the energy transaction information further includes information regarding a parking fee for the mobile object incurred when electricity is exchanged between the corresponding charging / discharging facility and the mobile object.

[0019] This allows the mobile agent to accurately estimate the costs incurred in energy trading, and therefore determine bidding conditions that are advantageous to the mobile agent.

[0020] Preferably, the energy trading information further includes information regarding an incentive to be given to the mobile object in response to the exchange of electricity between the corresponding charging / discharging facility and the mobile object.

[0021] This allows the mobile agent to accurately estimate the profits it will gain from energy trading, and therefore allows it to determine bidding conditions that are advantageous to the mobile agent.

[0022] Preferably, the energy trading management server further includes a determination unit that acquires information on buying and selling prices for each unit time slot in the individual trading market, and determines whether or not the acquired information on buying and selling prices for each unit time slot matches information on buying and selling prices for each unit time slot stored in the storage device.

[0023] This makes it possible to detect discrepancies between the buying and selling prices in the individual trading market and the buying and selling prices stored in the power management server, thereby preventing mobile objects bidding in the individual trading market from being disadvantaged due to the discrepancy in the buying and selling prices.

[0024] Preferably, the energy trading management server further includes a correction unit that acquires information on buying and selling prices for each unit time slot in the individual trading market, and corrects information on the buying and selling prices for each unit time slot stored in the storage device so as to match the acquired information on the buying and selling prices for each unit time slot.

[0025] This makes it possible to eliminate discrepancies between the buying and selling prices in the individual trading market and the buying and selling prices stored in the power management server, thereby preventing mobile objects bidding in the individual trading market from being disadvantaged due to the discrepancy in the buying and selling prices.

[0026] According to another aspect of the present disclosure, an energy trading processing device for a mobile object includes a communication circuit. The communication circuit transmits information on the mobile object participating in the energy trading market to the energy trading management server. The communication circuit receives energy trading information in the individual trading market that matches a search condition from the energy trading management server.

[0027] According to this, the mobile body power trading processing device (mobile body agent) can efficiently collect power trading information in the individual trading market for charging / discharging facilities that exist within a geographical area where the mobile body can receive and send power. In addition, the mobile body agent can determine bidding conditions for the mobile body's power trading while referring to the presented power trading information in the individual trading market, so that the mobile body can participate in power trading under favorable conditions.

[0028] Preferably, the mobile object energy trading processing device further includes a notification unit that notifies an owner of the mobile object of the energy trading information received by the communication circuit via a user interface.

[0029] According to this, the owner of the mobile unit can grasp the electricity trading information in the individual trading market where the mobile unit can bid. When a plurality of individual trading markets where the mobile unit can input electricity are presented, the owner of the mobile unit can compare the electricity trading information among the plurality of individual trading markets.

[0030] Preferably, the mobile object energy trading processing device further includes a determination unit that determines bidding conditions for trading of electricity by the mobile object based on the energy trading information in the individual trading market that matches the search conditions and the predicted usage status of the mobile object.

[0031] With this, the mobile agent can refer to the future usage status of the mobile agent and use the presented electricity trading information to determine bidding conditions so as to maximize profits in electricity trading.

[0032] Preferably, the determination unit calculates, based on the predicted usage status of the mobile body, an amount of power that the storage battery of the mobile body can charge and discharge per unit time period and a total amount of power that the mobile body can transfer to and from the charging and discharging facility. The determination unit determines a bid energy amount upper limit value for each unit time period for the mobile body, based on the calculated amount of power that the storage battery of the mobile body can charge and discharge per unit time period and the total amount of power that the mobile body can transfer to and from the charging and discharging facility, and the amount of power for each unit time period in an individual trading market that matches the search conditions. The determination unit determines the individual trading market to which the bid will be placed, the amount of power that the mobile body will transfer to and from the charging and discharging facility, and the purchase and sale price for each unit time period, based on the determined bid energy amount upper limit value and the purchase and sale price for each unit time period in the individual trading market that matches the search conditions.

[0033] With this, the mobile agent can determine the bidding conditions using the presented electricity trading information so as to maximize the profits in electricity trading within the range of the amount of electricity that the mobile agent's battery can charge and discharge, while referring to the future usage status of the mobile agent.

[0034] Preferably, the determination unit notifies the owner of the mobile object of the determined bidding conditions for the mobile object via a user interface. The determination unit executes a contract when approval is obtained from the owner of the mobile object.

[0035] According to this, bidding and contracting of mobile bodies are carried out under bidding conditions approved by the owner of the mobile body, so that electricity trading can be carried out in accordance with the intentions of the owner of the mobile body. Effect of the Invention

[0036] According to the present disclosure, it is possible to provide a mobile entity with information regarding energy transactions being bid on an individual trading market in P2P energy trading, so that the mobile entity can participate in energy transactions under favorable conditions.

[0038] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. The same or corresponding parts in the drawings are denoted by the same reference numerals, and their description will not be repeated.

[0039] [Embodiment 1] [Configuration Example of P2P Power Trading System] FIG. 1 is a diagram schematically showing a configuration example of a P2P (Peer to Peer) power trading system to which a power trading information providing system according to the present embodiment is applied.

[0040] As shown in FIG. 1, in the P2P power trading system, there are a charging / discharging facility agent 4 and a mobile agent 5. The charging / discharging facility agent 4 manages the bidding and contracting of the charging / discharging facilities owned by power consumers. The charging / discharging facility agent 4 includes a business office agent that manages the bidding and contracting of power consumers with large power demands such as factories, commercial facilities, railway stations, and airports, and a residential agent that manages the bidding and contracting of power consumers with normal power demands such as houses or small and medium-sized stores. The charging / discharging facility agent 4 corresponds to an embodiment of the "power trading processing device for charging / discharging facilities".

[0041] The mobile agent 5 manages the bidding and contracting of mobile bodies such as electric vehicles. The mobile body is equipped with a storage battery that can be charged from the outside and discharged to the outside. The mobile body is, for example, an electric vehicle, a hybrid vehicle, a plug-in hybrid vehicle, or an autonomous driving vehicle capable of transporting goods unmanned. Power consumers and mobile bodies submit bids through the agents in charge. The mobile agent 5 corresponds to an embodiment of the "power trading processing device for mobile bodies".

[0042] Each of the charging / discharging facility agent 4 and the mobile agent 5 can exchange information with an information processing device (server) constituting the P2P power trading market 1 through a communication network.

[0043] When P2P electricity trading using mobile devices takes place, there are two possible market forms: a "general trading market" and an "individual trading market." A "general trading market" is a market where agreements are made for electricity to be procured from electricity sellers to buyers via transmission lines in a power grid (a power grid for supplying electricity from large-scale power plants operated by power companies). An "individual trading market" is a market where agreements are made for electricity to be directly exchanged between one party in an electricity transaction, with the mobile device moving to the other party's location. For example, when a mobile device is the seller of electricity, an individual trading market makes an agreement for electricity to be procured by moving the mobile device to the location of the electricity buyer.

[0044] As shown in Fig. 1, each charging / discharging equipment agent 4 forms an individual trading market 3 for the charging / discharging equipment under management to make an agreement on the direct exchange of electricity between the charging / discharging equipment and a mobile object. That is, in the P2P trading market 1, one individual trading market 3 is formed for an electricity consumer who owns a charging / discharging equipment. The individual trading market 3 can be configured by a server managed by the electricity consumer. Alternatively, a plurality of individual trading markets 3 may be collectively configured on one server.

[0045] In each individual trading market 3, electricity consumers submit bids for buying or selling for each unit time period via charging / discharging equipment agents 4, and multiple mobile objects submit bids for buying or selling for each unit time period via mobile object agents 5.

[0046] In this specification, a "unit time slot" refers to one of a plurality of time slots obtained by dividing the time during which electricity trading takes place into a predetermined time length set in the P2P energy trading market 1. Currently, in Japan, 24 hours are divided into 48 segments, so the length of one unit time slot is 30 minutes. Electricity trading is carried out for each amount of electricity transmitted within a unit time slot (electricity x length of unit time slot).

[0047] Each of the sellers and buyers submits a bid for a combination of power amount and price for each unit time period. A contract is made when the seller's bidding conditions match the buyer's bidding conditions. In the individual trading market 3, power consumers usually submit selling bids and mobile entities can submit buying bids. In addition, in a situation where a power consumer performs peak shaving, which will be described later, the power consumer can submit buying bids and the mobile entity can submit selling bids.

[0048] The charging / discharging equipment agent 4 issues identification information for identifying the individual trading market 3 (hereinafter also referred to as "market ID") and a password for logging in to the individual trading market, and assigns them to the individual trading market 3. This allows only the mobile agent 5 that has obtained the market ID and password to place a bid in the individual trading market 3. Note that there may be one or more individual trading markets that the mobile agent can select as the bid destination.

[0049] For a mobile body, being able to procure electricity to charge a storage battery through the individual trading market 3 is extremely useful in reducing electricity costs. For example, if a storage battery can be charged using a charging / discharging facility present in the living area of ​​the owner of the mobile body, the cost and effort of moving the mobile body to the charging / discharging facility can be reduced. Alternatively, if a storage battery can be charged using a charging / discharging facility present on the travel route of the mobile body from the current position to the destination, this will be advantageous in terms of cost and effort.

[0050] Furthermore, for example, if the owner of a mobile object can charge a storage battery while shopping at a commercial facility using charging and discharging equipment installed in the facility, it will be possible to improve the convenience of the owner of the mobile object. In order to realize the procurement of electricity through such an individual trading market 3, it is necessary to build a system that allows the owner of the mobile object to obtain information on the individual trading market that is advantageous to the mobile object.

[0051] On the other hand, for large-scale power consumers who consume a large amount of power, such as factories, commercial facilities, railway stations, and airports, it is very useful to be able to procure power without using the transmission lines of the grid power grid through the individual trading market 3 in order to reduce power costs. In general, when procuring power through the grid power grid (including procuring power in the general trading market), the basic charge in the power rate is determined by the maximum amount of power demand in the past year. Therefore, in order to reduce power costs, power consumers will try to suppress the maximum amount of power received from the grid power grid. However, since the power demand of power consumers may increase transiently, in such cases, especially large-scale power consumers may take a measure called "peak cut" in which the amount of power received from the grid power grid is suppressed to below a predetermined value during a time period (peak time period) when the amount of power used per unit time period (usually 30 minutes) exceeds a predetermined value. If the excess amount of power is covered by existing storage batteries or generators to implement this peak shaving, the introduction of such equipment will require significant costs. On the other hand, if the power contracted in the individual trading market 3 described above can be procured during peak shaving, the introduction of such equipment will be unnecessary, which will be advantageous in terms of costs.

[0052] Here, when an electric power consumer intends to enter into an electric power transaction with a mobile object through the individual trading market 3 in order to cut peak demand at the electric power consumer, it is important to also consider the profit and loss and costs involved in procuring electric power at the mobile object. If the mobile object cannot find a benefit that exceeds the cost of accommodating electric power through the individual trading market 3, not many mobile objects will gather in the individual trading market 3 where the electric power consumer is bidding, and as a result, the amount of electric power that the electric power consumer can procure may be limited to the total amount of electric power stored in the mobile object within the electric power consumer's jurisdiction. Therefore, in order to enable the electric power consumer to procure electric power through the individual trading market 3, it is necessary to build a system that enables the mobile object (owner) to grasp the benefit of electric power trading in the individual trading market.

[0053] In this embodiment, an energy trading information providing system is described that is configured to provide information regarding energy trading in which energy consumers are bidding in the individual trading market 3 to a mobile entity so that the mobile entity can participate in energy trading under favorable conditions in P2P energy trading.

[0054] <Overall configuration of the electricity trading information system> 2 is a diagram showing an outline of the overall configuration of an energy trade information system according to the present embodiment. As shown in FIG. 2, the energy trade information system 100 includes a management server 8, a charging / discharging equipment agent 4, and a mobile agent 5.

[0055] The management server 8 is a server that manages electricity trading in the P2P energy trading market. The management server 8 is configured to be able to communicate with each of the charging / discharging equipment agent 4, the mobile agent 5, and the P2P energy trading market 1 via the communication network NW. The management server 8 corresponds to one embodiment of the "energy trading management server."

[0056] Specifically, the management server 8 includes a processing device 80, a database (DB) 86, and a communication interface (I / F) 88. The processing device 80 includes a processor 82 and a memory 84.

[0057] The processor 82 is, for example, a central processing unit (CPU) and is configured to execute predetermined calculation processes described in a program. The calculation processes include searching for individual trading markets, which will be described later.

[0058] The memory 84 includes a read only memory (ROM) and a random access memory (RAM). The ROM stores the programs executed by the processor 82. The RAM temporarily stores data generated by the execution of the programs in the processor 82 and data input via the communication I / F 88. The RAM also functions as a temporary data memory used as a working area.

[0059] The database 86 stores information (hereinafter also referred to as "power trading information") relating to power trading in each individual trading market 3 included in the P2P power trading market 1. This power trading information includes location information of charging / discharging equipment where power is exchanged, and information on bidding conditions submitted by power consumers in the individual trading market. The power trading information will be described in detail later.

[0060] The communication I / F 88 is configured to enable bidirectional communication with external devices of the management server 8 (such as the charging / discharging facility agent 4, the mobile agent 5, and the P2P energy trading market 1) via the communication network NW.

[0061] The charging / discharging equipment agent 4 includes a processor 40, a memory 42, and a communication I / F 44. The processor 40 is, for example, a CPU, and is configured to execute a predetermined calculation process described in a program. This calculation process includes bidding for energy trading in the P2P energy trading market 1.

[0062] The memory 42 includes a ROM and a RAM. The ROM stores the programs executed by the processor 40. The RAM temporarily stores data generated by the execution of the programs in the processor 40 and data input via the communication I / F 44. The RAM also functions as a temporary data memory used as a working area.

[0063] The communication I / F 44 is configured to enable bidirectional communication with external devices of the charging / discharging facility agent 4 (such as the P2P energy trading market 1, the management server 8, and the mobile agent 5) via the communication network NW.

[0064] The management server 8 may be configured integrally with an information processing device (server) that constitutes the P2P energy trading market 1, or may be configured separately from the information processing device.

[0065] The charging / discharging equipment agent 4 may be configured using a computer device provided in the power consumer, or may be configured using cloud computing.

[0066] The mobile agent 5 includes a processor 50, a memory 52, a communication I / F 54, and an input / output circuit (I / O) 56. The processor 50 is, for example, a CPU, and is configured to execute a predetermined calculation process described in a program. The calculation process includes bidding for energy trading in the P2P energy trading market 1.

[0067] The memory 52 includes a ROM and a RAM. The ROM stores the programs executed by the processor 50. The RAM temporarily stores data generated by the execution of the programs in the processor 50 and data input via the communication I / F 54 and the I / O 56. The RAM also functions as a temporary data memory used as a working area.

[0068] The communication I / F 54 is configured to enable bidirectional communication with external devices (such as the P2P energy trading market 1, the management server 8, and the charging / discharging equipment agent 4) of the mobile agent 5 via the communication network NW. The communication I / F 54 corresponds to one embodiment of a "communication circuit."

[0069] The input / output circuit 56 is connected to a user interface (UI) 6. The user interface 6 is, for example, a navigation device mounted on a mobile object or a mobile terminal (tablet, smartphone, etc.) operated by the owner of the mobile object. The processor 50 can output information to the user interface 6 through the input / output circuit 56, and also receives an input of a signal indicating an operation instruction given to the user interface 6. The input / output circuit 56 corresponds to one embodiment of a "notification unit."

[0070] The mobile agent 5 may be configured using a computer device provided in the mobile object, or may be configured using cloud computing.

[0071] <Functional configuration of the electricity trading information system> 3 is a diagram for explaining the flow of processes executed in the energy trade information provision system 100. Note that the reference characters (1) to (9) in the diagram indicate the order in which the processes are performed. However, the order of the processes is not limited to this.

[0072] As shown in Fig. 3, electricity consumers submit bids in the individual trading market 3 formed within the P2P electricity trading market 1 via charging / discharging equipment agents 4 (see (1) in the figure). The "bidding conditions for electricity trading" presented by the charging / discharging equipment agents 4 include the time periods during which electricity can be exchanged at the corresponding charging / discharging equipment, the amount of electricity per unit time period during those time periods, and the buying and selling prices per unit time period for the exchange of that amount of electricity.

[0073] The charging / discharging equipment agent 4 transmits power trading information, including the bidding conditions presented in the individual trading market 3, to the management server 8 (see (2) in the figure). In addition to the above-mentioned bidding conditions, the power trading information includes location information of the charging / discharging equipment where power is exchanged.

[0074] When the management server 8 receives the energy trading information from the charging / discharging equipment agent 4, it stores the received energy trading information in a database 86. As shown in Fig. 3, data on the energy trading information for each individual trading market 3 is registered as "individual trading market data" in the database 86. In this way, the database 86 of the management server 8 stores energy trading information for a plurality of individual trading markets 3 included in the P2P energy trading market 1.

[0075] Fig. 4 is a diagram for explaining an example of the configuration of the energy trading information. As shown in Fig. 4, the energy trading information includes the market ID and password of the individual trading market 3, and the location information of the corresponding charging / discharging facility (such as the address of the charging / discharging facility).

[0076] The electricity trading information further includes bidding conditions for electricity consumers to trade electricity in the individual trading market 3. Specifically, the bidding conditions include "time periods during which electricity consumers can trade electricity", "energy volume per unit time period in those time periods", and "buying and selling prices per unit time period".

[0077] "Time periods during which electricity can be traded" correspond to time periods during which electricity can be exchanged at charging / discharging facilities. In Figure 4, the availability of electricity exchange for each unit time period is shown. Specifically, "◯" indicates that electricity exchange is possible at charging / discharging facilities, and "-" indicates that electricity exchange is not possible at charging / discharging facilities.

[0078] "Electricity amount per unit time period" refers to the amount of electricity that can be exchanged by the charging / discharging equipment during the unit time period. During the unit time period during which the charging / discharging equipment can supply power, electricity consumers can make selling bids in the individual trading market. On the other hand, during the unit time period during which the charging / discharging equipment can receive power, electricity consumers can make buying bids in the individual trading market.

[0079] The "buying and selling price per unit time slot" is the price at which the amount of electricity per unit time slot is sold or purchased.

[0080] The energy trading information further includes information on costs incurred by the mobile object when transferring power to and from the charging / discharging facility, such as parking fees when the mobile object is parked under an electricity consumer.

[0081] The energy trading information further includes information about incentives. An incentive is something given to a mobile object by an energy consumer through an energy trading, and is typically a monetary reward. Note that the form of the incentive is not limited to a monetary reward, and can be set appropriately by each energy consumer.

[0082] Returning to FIG. 3, the mobile agent 5 communicates with the management server 8 and provides information about the mobile agents to be managed, thereby using the management server 8 to collect energy trading information in the individual trading market 3 for which it is a potential bidder.

[0083] Specifically, first, the mobile agent 5 transmits information about the mobile object to be managed to the management server 8 (see (3) in the figure). This mobile object information includes information indicating a geographical range within which the mobile object can receive and exchange power. The geographical range within which the mobile object can receive and exchange power may include the current location of the mobile object or the area in which the owner of the mobile object lives.

[0084] Alternatively, when a destination point is set in a navigation device mounted on the moving object, the geographical range may include the destination point and a travel route of the moving object to the destination point set by the owner of the moving object through the navigation device. Note that, when the moving object is an electric vehicle configured to be capable of automatic driving, the geographical range may include a travel route created in advance.

[0085] The mobile agent 5 can collect information on these mobile objects through a processor (e.g., an ECU (Electronic Control Unit)) provided in the mobile object. The mobile agent 5 may be configured to collect travel data (trip information) from the past to the present of the mobile object, and determine an area that will be a living area based on the collected travel data.

[0086] The information on the mobile object may include information indicating the time period during which the mobile object can receive and exchange electric power, in addition to the information indicating the geographic range described above. The mobile object agent 5 is configured to collect information such as the mobile object's travel data and data on the connection status to charging / discharging equipment at home, etc., and to predict the future usage status of the mobile object (future travel data, connection location of charging / discharging equipment, stopping time, etc.) based on the collected information. The mobile object agent 5 predicts the time period during which the mobile object can receive and exchange electric power based on the predicted usage status of the mobile object, and transmits the prediction result to the management server 8.

[0087] When the management server 8 receives information about the mobile object from the mobile agent 5, it sets search conditions for searching for individual trading markets 3 that may be potential bidders for the mobile object based on the received information (see (4) in the figure).

[0088] The search conditions may include geographical conditions. The geographical conditions may be set using information indicating a geographical range in which the mobile body can receive and exchange power. Specifically, when the information indicating the geographical range in which the mobile body can receive and exchange power is information indicating the current position of the mobile body, the management server 8 may set the geographical conditions to include a range in which the distance from the current position of the mobile body is equal to or less than a predetermined value set in advance.

[0089] Alternatively, if the information indicating the geographical range within which a mobile body can receive and provide power is information indicating the living area of ​​the owner of the mobile body, the management server 8 can set the area that is the living area of ​​the owner of the mobile body as the geographical condition.

[0090] Alternatively, if the information indicating the geographical range within which a mobile body can receive and provide power is information indicating the travel route of the mobile body from the current location to the destination point, the management server 8 can set the travel route and the destination point as the geographical conditions.

[0091] The search conditions may further include a time condition. The time condition may be set using information indicating a time period during which the mobile object can receive and exchange power. Specifically, the management server 8 may set the time condition to include a time period during which the mobile object can receive and exchange power.

[0092] Next, the management server 8 uses the set search conditions to search for individual trading market data that matches the search conditions from among multiple individual trading market data registered in the database 86 (see (4) in the figure). This search extracts individual trading market data whose location information of the charging / discharging equipment matches the above-mentioned geographical conditions. If the search conditions include geographical conditions and temporal conditions, the search extracts individual trading market data whose location information of the charging / discharging equipment matches the geographical conditions and whose time period during which electricity can be traded at the charging / discharging equipment matches the temporal conditions.

[0093] The extracted individual trading market data corresponds to the electricity trading information in the individual trading market 3 where the mobile unit can bid. The management server 8 presents the search result to the mobile agent 5 (see (5) in the figure). As described above, the search result includes the electricity trading information in the individual trading market 3 where the mobile unit can bid (see FIG. 4). Therefore, for the individual trading market 3 where the mobile unit can bid, information on bidding conditions, parking fees, and incentives for electricity trading, together with location information of charging / discharging equipment, is presented to the mobile agent 5.

[0094] According to this, the mobile unit agent 5 is presented with electricity trading information in the individual trading market 3 for charging / discharging facilities that are present within a geographical range where the mobile unit can receive and send electricity, so that it can efficiently collect electricity trading information in individual trading markets where the mobile unit can bid. Furthermore, the mobile unit agent 5 can determine bidding conditions for the mobile unit's electricity trading while referring to the presented electricity trading information in at least one individual trading market 3, so that the mobile unit can participate in electricity trading under favorable conditions.

[0095] The mobile object agent 5 notifies the owner of the mobile object of the search results presented by the management server 8 via the user interface 6 (see (6) in the figure). As described above, the user interface 6 is a navigation device mounted on the mobile object or a mobile terminal (smartphone, tablet, etc.) operated by the owner of the mobile object.

[0096] Fig. 5 is a diagram showing a first example of a search result displayed on the user interface 6. Fig. 5 shows a schematic diagram of a screen displayed on the display of a navigation device mounted on the mobile body 200. An area RGN1 in the diagram indicates a range in which the distance from the current position of the mobile body 200 is equal to or less than a preset predetermined value. The screen shows position information of charging / discharging facilities 300 existing within the area RGN1. For each charging / discharging facility 300, power trading information in the individual trading market corresponding to the charging / discharging facility 300 is further shown.

[0097] This allows the owner of the mobile object 200 to grasp the electricity trading information in the individual trading market 3 which may be a bidder for the mobile object 200. When a plurality of individual trading markets 3 which may be input destinations are displayed as in Fig. 5, the owner of the mobile object 200 can compare the electricity trading information between the plurality of individual trading markets 3.

[0098] Fig. 6 is a diagram showing a second example of the search result displayed on the user interface 6. Like Fig. 5, Fig. 6 also shows a schematic diagram of a screen displayed on the display of the navigation device of the mobile object 200.

[0099] As shown in Fig. 6, the screen shows a travel route R1 from the current position of the moving body to the destination point. This travel route R1 is searched by the navigation device in response to an input of the destination point, and is selected by the owner of the moving body. If the moving body 200 is configured to be capable of automatic driving, a travel route created in advance will be displayed.

[0100] The screen shows location information of charging / discharging facilities 300 existing around the travel route R1. For each charging / discharging facility 300, power trading information in the individual trading market 3 corresponding to the charging / discharging facility 300 is further shown. Although not shown in the figure, the user interface 6 can further display location information of charging / discharging facilities 300 existing around the destination point and the power trading market in the individual trading market corresponding to the charging / discharging facility 300.

[0101] In the second example shown in Fig. 7, similarly to the first example shown in Fig. 6, the owner of the mobile body 200 can grasp the energy trading information of the charging / discharging facilities 300 present in the vicinity of the travel route R1 to the destination point. When there are multiple charging / discharging facilities 300 in the vicinity of the travel route R1, the owner of the mobile body 200 can compare the energy trading information among multiple individual trading markets 3.

[0102] Returning to Fig. 3, the mobile agent 5 searches for the individual trading market 3 in which the mobile body will place a bid and the bidding conditions for the electricity trading, using the search results presented by the management server 8 (see (7) in the figure). Specifically, the mobile agent 5 determines, as the bidding conditions, the individual trading market 3 in which the mobile body will place a bid, the amount of electricity to be charged / discharged to the battery of the mobile body, and the buying / selling price for each unit time period.

[0103] For example, as shown in Figure 5, when electricity trading information in multiple individual trading markets 3 corresponding to multiple charging / discharging facilities located within a range where the distance from the current location of the mobile body is less than a predetermined value is presented, the mobile body agent 5 determines the bidding conditions using the presented electricity trading information in the multiple individual trading markets 3, while referring to the future usage status of the mobile body, so as to maximize the profit in electricity trading within the range of the amount of electricity that the mobile body's storage battery can charge and discharge.

[0104] Alternatively, as shown in Figure 6, when electricity trading information in multiple individual trading markets corresponding to multiple charging / discharging facilities located in the vicinity of the driving route to the destination is presented, when it is predicted from the future usage status of the mobile object that the storage battery will need to be charged before arriving at the destination, the mobile object agent 5 determines the bidding conditions using the presented electricity trading information in the multiple individual trading markets 3 so as to maximize the profit in electricity trading within the range of the amount of electricity that the storage battery of the mobile object can charge and discharge, without significantly changing the driving route to the destination or the arrival time at the destination.

[0105] In addition, when it is predicted that the storage battery will need to be charged after arriving at the destination, the mobile agent 5 determines the bidding conditions using the presented electricity trading information in the individual trading market 3 for charging / discharging facilities located around the destination so as to maximize the profit in trading electricity within the range of the amount of electricity that the mobile battery can charge and discharge, without moving the mobile body further from the destination.

[0106] The mobile agent 5 submits a bid to the individual trading market 3, which is the target of the bid, in accordance with the determined bidding conditions (see (8) in the figure). Specifically, the mobile agent 5 logs into the individual trading market 3, which is the target of the bid, using the market ID and password included in the energy trading information, and submits a buy or sell bid for each unit time slot in accordance with the determined bidding conditions. An energy transaction is concluded between the mobile agent 5 and the charging / discharging equipment agent 4 for which the bidding conditions match (see (9) in the figure).

[0107] <Functional configuration of management server and mobile agent> Next, the functional configuration of the management server 8 and the mobile agent 5 will be described with reference to FIG. 7 and FIG.

[0108] Fig. 7 is a block diagram showing the functional configuration of the management server 8. As shown in Fig. 7, the management server 8 includes a registration unit 90, a database 86, a search unit 91, a setting unit 92, an input unit 93, and a presentation unit 94. These functional configurations are realized by the processor 82 executing a predetermined program in the management server 8 shown in Fig. 2.

[0109] The registration unit 90 receives energy trading information from the charging / discharging equipment agent 4. As shown in FIG. 4 , the energy trading information includes the bidding conditions presented by the charging / discharging equipment agent 4 to the individual trading market 3, location information of the charging / discharging equipment where electricity is exchanged, and the market ID and password of the individual trading market 3. The registration unit 90 registers data indicating the received energy trading information of the individual trading market 3 (individual trading market data) in the database 86. The registration unit 90 registers energy trading information for each of the multiple individual trading markets 3 included in the P2P energy trading market 1 in the database 86.

[0110] The input unit 93 receives information about the mobile object from the mobile object agent 5. The information about the mobile object includes at least information indicating a geographical range in which the mobile object can receive and exchange electric power. The geographical range in which the mobile object can receive and exchange electric power is, for example, the current location of the mobile object, the living area of ​​the owner of the mobile object, or the travel route of the mobile object from the current location to the destination point.

[0111] The setting unit 92 sets search conditions for searching for the individual trading market 3 to which the mobile body can bid, based on the information about the mobile body. The search conditions include geographical conditions set based on information indicating a geographical range in which the mobile body can receive and send electricity.

[0112] The search unit 91 uses the search conditions set by the setting unit 92 to search for individual trading market data that matches the search conditions from among a plurality of individual trading market data stored in the database 86. In this search, individual trading market data in which location information of the charging / discharging equipment matches the geographical conditions included in the search conditions is extracted.

[0113] The presentation unit 94 presents the individual trading market data extracted by the search unit 91 to the mobile agent 5. The presented individual trading market data includes electricity trading information in the individual trading market 3 where the mobile body can bid. Therefore, for the individual trading market 3 where the mobile body can bid, information on the location information of the charging / discharging equipment, bidding conditions for electricity trading, parking fees, and incentives is presented to the mobile agent 5.

[0114] Fig. 8 is a block diagram showing the functional configuration of the mobile agent 5. As shown in Fig. 8, the mobile agent 5 includes a user usage prediction unit 60, a unit time tradable energy amount detection unit 61, a total tradable energy amount calculation unit 62, a bid energy amount upper limit determination unit 63, an input unit 64, a traded energy amount prediction unit 65, a buying and selling price prediction unit 66, and a bidding condition determination unit 67.

[0115] The user usage prediction unit 60 collects data stored in the mobile body, such as past and present operation data (trip information) of the mobile body, SOC (State Of Charge) fluctuation data of the storage battery, and connection status to charging and discharging equipment, through a calculation processing device (e.g., ECU) provided in the mobile body, and predicts future usage status of the mobile body based on the collected data. Future usage status of the mobile body includes, for example, future driving data, connection locations to charging and discharging equipment, and stopping time.

[0116] The unit time tradable energy amount detection unit 61 uses the prediction result by the user usage prediction unit 60 to detect the amount of energy that can be charged / discharged to the storage battery of the mobile body per unit time slot when the mobile body is connected to charging / discharging equipment in the individual trading market 3 that is the bidder. The amount of energy that can be charged / discharged per unit time slot corresponds to the amount of energy that can be traded per unit time slot. The charging / discharging equipment with which the mobile body receives and sends power is the charging / discharging equipment that corresponds to at least one individual trading market 3 that is presented by the management server 8 and that is a potential bidder. The amount of energy that can be traded per unit time slot may be detected for each of the charging / discharging equipment in at least one individual trading market 3.

[0117] The total tradable power calculation unit 62 calculates the amount of power that can be charged and discharged in the mobile body's storage battery by referring to the SOC fluctuation data of the storage battery, etc. The amount of power that can be discharged from the storage battery corresponds to the amount of power from the storage amount of the storage battery to the lower limit of the SOC. The amount of power that can be charged to the storage battery corresponds to the amount of power from the storage amount of the storage battery to the upper limit of the SOC. Specifically, the total tradable power calculation unit 62 calculates the amount of power that can be charged and discharged in the storage battery by subtracting the predicted value of the amount of power consumed for the traveling of the mobile body estimated from the future traveling data from the current storage amount of the storage battery detected from the SOC fluctuation data of the storage battery or the predicted value of the future storage amount of the storage battery estimated from the SOC fluctuation data.

[0118] The total tradable electricity calculation unit 62 further calculates the total amount of electricity that can be exchanged between the charging / discharging equipment and the storage battery while the mobile body is stopped, based on the planned time that the mobile body is stopped under the charging / discharging equipment and the charging / discharging speed of the charging / discharging equipment during that stopping time.

[0119] The total tradeable electricity calculation unit 62 ultimately calculates the smaller of the amount of electricity that can be charged and discharged in the storage battery and the amount of electricity that can be exchanged between the charging / discharging equipment and the storage battery as the total amount of tradeable electricity.

[0120] The input unit 64 receives, as a search result from the management server 8, an input of at least one individual trading market data item that can be a bidder.

[0121] The traded energy amount prediction unit 65 predicts the amount of energy traded by power consumers from the present to the future in each individual trading market, based on at least one individual trading market data acquired through the input unit 64. The traded energy amount prediction unit 65 predicts the amount of energy traded by power consumers for each unit time period for each individual trading market, based on the bidding conditions of the power consumers included in the individual trading market data.

[0122] The buying and selling price prediction unit 66 predicts the buying and selling prices for each unit time slot in each individual trading market by referring to at least one individual trading market data acquired through the input unit 64. The buying and selling price prediction unit 66 predicts the buying and selling prices for each unit time slot in each individual trading market based on the bidding conditions of electricity consumers included in the individual trading market data.

[0123] The bid energy upper limit determination unit 63 determines the upper limit of the bid energy amount for the mobile body for each unit time slot. The bid energy upper limit for the mobile body for each unit time slot corresponds to the upper limit of the amount of energy charged and discharged to the storage battery of the mobile body, which is set for each unit time slot. Therefore, the amount of energy for each unit time slot in the bidding conditions for the mobile body is determined to be equal to or less than the bid energy upper limit. Specifically, when the tradable energy amount for each unit time slot and the total amount of tradable energy are obtained, the bid energy upper limit determination unit 63 determines the upper limit of the bid energy amount for each unit time slot so that the bid energy amount is allocated according to the size of the tradable energy amount of the power consumer for each unit time slot.

[0124] When the upper limit of the bid amount of energy for each unit time slot is determined, the bidding condition determination unit 67 determines the bidding conditions so as to maximize the profit for the mobile unit, using the predicted value of the buying and selling price for each unit time slot in each individual trading market. Note that "maximizing the profit" means minimizing the loss when the loss occurring in the energy trading is larger than the profit.

[0125] The bidding condition determination unit 67 calculates the profit and loss incurred in the electricity trading for each unit time period. This profit and loss includes the cost and incentives incurred in the electricity trading. Specifically, the profit and loss incurred in the electricity trading includes the profit and loss obtained by multiplying the amount of electricity traded by the purchase and sale price, the parking fee for the mobile body incurred during the transaction, and the monetary reward given for the electricity trading.

[0126] The bidding condition determination unit 67 searches for bidding conditions that maximize the profit for the mobile body based on the calculated profit and loss. In searching for bidding conditions, for example, an objective function is set that calculates the cost incurred in the power transaction as an index representing the loss in the power transaction. Under the constraint condition on the upper and lower limit values ​​of the SOC that should be satisfied in the storage battery of the mobile body (the range in which the storage battery can be charged and discharged), the amount of power to be sold or purchased that minimizes the objective function is searched for. Note that the process of optimizing the objective function may be a process using any numerical calculation such as linear programming or convex optimization.

[0127] When the optimization process of the objective function is executed and the optimal conditions are detected, an individual trading market 3 to which the bidders will bid is selected for each unit time slot. In addition, the buying and selling prices used in the optimal conditions and the amount of power desired to be purchased and the amount of power desired to be sold found in the optimal conditions are determined as the bidding conditions.

[0128] The bidding condition determination unit 67 submits a bid for electricity trading to the individual trading market 3 selected as the bidder for each unit time period in accordance with the determined bidding conditions. When a bid in the individual trading market 3 is agreed upon, the mobile object travels to the electricity consumer with which the transaction is made, and exchanges electricity with the charging / discharging equipment installed at the electricity consumer.

[0129] The bidding condition determination unit 67 may be configured to notify the owner of the mobile object of the determined bidding conditions via the user interface 6 prior to bidding. In this configuration, bidding is conducted only when the owner of the mobile object approves the notified bidding conditions.

[0130] As described above, in the energy trade information providing system according to the first embodiment, the management server 8 is configured to search for energy trade information in individual trading markets 3 that can be potential bidders for the mobile unit, based on the information about the mobile unit provided by the mobile unit agent 5, and to present the search results to the mobile unit agent 5. In this way, the mobile unit agent 5 can determine bidding conditions for the mobile unit's energy trade so as to maximize the profits for the mobile unit, while referring to energy trade information in at least one individual trading market 3 that can be a potential bidder. As a result, the mobile unit can participate in energy trade under favorable conditions.

[0131] [Embodiment 2] In the above-mentioned embodiment 1, a configuration has been described in which the management server 8 presents electricity trading information in the individual trading market, which has been presented by the charging / discharging equipment agent 4 and stored in the database 86, in response to a request from the mobile agent 5.

[0132] However, in the above configuration, it may happen that the bidding conditions included in the electricity trading information stored in the database 86 do not match the bidding conditions of the charging / discharging equipment agent 4 in the P2P trading market 1. For example, there may be a discrepancy between the buying and selling price of electricity for each unit time slot in a certain individual trading market 3 and the buying and selling price for each unit time slot included in the electricity trading information of the individual trading market 3 stored in the database 86 of the management server 8. Such a discrepancy in electricity trading information may occur due to the intentional or negligent acts of electricity consumers. The discrepancy in electricity trading information may cause a disadvantage to a mobile object that makes a bid in the individual trading market 3.

[0133] Therefore, in the energy trading information provision system according to the second embodiment, the management server 8 is configured to determine whether or not the energy trading information of the individual trading market 3 stored in the database 86 matches the energy trading information of the individual trading market 3 in the P2P energy trading market 1. Note that the overall configuration of the energy trading information provision system, and the configurations of the charging / discharging equipment agent 4 and the mobile object agent 5 are basically the same as those in the first embodiment, and therefore description thereof will not be repeated.

[0134] Fig. 9 is a block diagram showing a functional configuration of a management server 8 in an energy trade information provision system according to embodiment 2. The basic configuration of the management server 8 shown in Fig. 9 is similar to that of the management server 8 shown in Fig. 7, except that a determination unit 95 is added. The functional configuration shown in Fig. 9 is realized by the processor 82 executing a predetermined program in the management server 8 shown in Fig. 2.

[0135] The determination unit 95 acquires bidding conditions from electricity consumers in the individual trading market 3 through communication with a certain individual trading market 3 in the P2P energy trading market 1. The bidding conditions include a time period during which the electricity consumers can trade electricity, an amount of electricity per unit time period in the time period, and a buying and selling price per unit time period.

[0136] The determination unit 95 reads out data (individual trading market data) on electricity trading information in the individual trading market 3 from the database 86. The determination unit 95 compares the bidding conditions included in the read individual trading market data with the bidding conditions in the individual trading market 3 acquired from the P2P energy trading market 1 to determine whether the two bidding conditions match. If the two bidding conditions do not match (for example, if the buying and selling prices do not match), the determination unit 95 notifies the charging and discharging equipment agent 4 of the determination result.

[0137] The charging / discharging equipment agent 4 that has received the notification transmits new energy trading information of the individual trading market 3 in the P2P energy trading market 1 to the management server 8. In the management server 8, the registration unit 90 updates the individual trading market data stored in the database 86 by overwriting the individual trading market data stored in the database 86 with the newly transmitted bidding conditions.

[0138] The above-mentioned determination process by the determination unit 95 may be configured to be executed periodically, or may be configured to be executed when a request is received from the mobile agent 5.

[0139] The management server 8 according to the second embodiment can present to the mobile agent 5 electricity trading information based on the bidding conditions in the actual electricity trading in the individual trading market 3. This makes it possible to prevent a mobile agent making a bid in the individual trading market 3 from being disadvantaged due to a discrepancy in the electricity trading information.

[0140] [Embodiment 3] Fig. 10 is a block diagram showing a functional configuration of a management server 8 in an energy trade information provision system according to embodiment 3. The basic configuration of the management server 8 shown in Fig. 10 is similar to that of the management server 8 shown in Fig. 7, but differs in that a correction unit 96 is added. The functional configuration shown in Fig. 10 is realized by the processor 82 executing a predetermined program in the management server 8 shown in Fig. 2.

[0141] The correction unit 96 acquires bidding conditions of electricity consumers in the individual trading market 3 through communication with a certain individual trading market 3 in the P2P trading market 1. The bidding conditions include a time period during which the electricity consumers can trade electricity, an amount of electricity per unit time period in the time period, and a buying and selling price per unit time period.

[0142] The correction unit 96 reads out data (individual trading market data) on the electricity trading information in the individual trading market 3 from the database 86. The correction unit 96 compares the bidding conditions included in the read individual trading market data with the bidding conditions in the individual trading market 3 acquired from the P2P energy trading market 1, to determine whether the two bidding conditions match.

[0143] If the two bidding conditions do not match (for example, if the buying and selling prices do not match), the correction unit 96 corrects the individual trading market data stored in the database 86 using the bidding conditions acquired from the P2P energy trading market 1. The correction unit 96 corrects the bidding conditions in the individual trading market data stored in the database 86 to the bidding conditions acquired from the P2P energy trading market 1.

[0144] Like the management server 8 according to the second embodiment, the management server 8 according to the third embodiment can also present to the mobile agent 5 energy trading information based on the bidding conditions in the actual energy trading in the individual trading market 3. This makes it possible to prevent a mobile agent making a bid in the individual trading market 3 from being disadvantaged due to a discrepancy in the energy trading information.

[0145] [Embodiment 4] Fig. 11 is a block diagram showing a functional configuration of a management server 8 in an energy trade information provision system according to embodiment 4. The basic configuration of the management server 8 shown in Fig. 11 is similar to that of the management server 8 shown in Fig. 7, but the configuration of a registration unit 90 is different. The functional configuration shown in Fig. 11 is realized by the processor 82 executing a predetermined program in the management server 8 shown in Fig. 2.

[0146] 11 , the registration unit 90 receives, from the charging / discharging equipment agent 4, location information of the charging / discharging equipment where electricity is exchanged, as well as the market ID and password of the individual trading market 3. The registration unit 90 also receives, from the individual trading market 3 in the P2P energy trading market 1, information on the bidding conditions, parking fees, and incentives that the charging / discharging equipment agent 4 has presented to the individual trading market 3. The registration unit 90 associates the information received from the individual trading market 3 with the location information of the charging / discharging equipment received from the charging / discharging equipment agent 4, and registers the information in the database 86 as data indicating electricity trading information (individual trading market data). The registration unit 90 registers electricity trading information for each of the multiple individual trading markets 3 included in the P2P energy trading market 1 in the database 86.

[0147] As described above, in the fourth embodiment, the registration unit 90 is configured to obtain, from the energy trading information, information on bidding conditions, parking fees, and incentives through communication with the individual trading market 3. The P2P energy trading market 1 is generally configured with a processing device (server) that is highly resistant to information tampering. By configuring the registration unit 90 to obtain information such as bidding conditions, which is important in energy trading, from the P2P energy trading market 1, it is possible to improve the reliability of the energy trading information provided to the mobile agent.

[0148] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. The scope of the present disclosure is defined by the claims, not by the description of the embodiments described above, and is intended to include all modifications within the meaning and scope of the claims.
