Abstract

If a power node has a scheduled exit time, it should be appropriately classified as a primary power source candidate, auxiliary power source candidate, or short-term supply candidate before being allocated to a demand point or critical load equipment. [Solution] The central control device 100 acquires demand information, including the scheduled supply end time or required supply time, for demand points or critical load equipment 500, and acquires node status information, including scheduled exit time information, for multiple power nodes 300A, 300B, and 300C. The central control device 100 compares the scheduled supply end time or required supply time with the scheduled exit time, excludes power nodes whose scheduled exit time is earlier than the scheduled supply end time from the main power candidate list, and classifies them as auxiliary power candidate lists or short-term supply candidate lists. Furthermore, it generates a power allocation plan based on the classification results.

Description

Technical Field

[0001] The present invention relates to a power node allocation control technology in a distributed power network having a plurality of power nodes, and particularly, for a plurality of power nodes including electric vehicles, bidirectional charging / discharging devices connected to the electric vehicles, portable batteries, mobile bodies with generators, and other distributed power sources, a distributed power node supply role determination system, a supply role determination method, a management device, and a program for determining a supply role of a power node to be allocated to a demand location or an important load facility in consideration of withdrawal scheduled time information based on the intention or plan of an owner, user, or operation manager.

[0002] More specifically, the present invention obtains demand information including required power, required power amount, scheduled supply start time, scheduled supply end time, required supply time, priority, etc. for a demand location or an important load facility, obtains node state information including available output, remaining power amount, connection state, communication state, withdrawal scheduled time information, etc. for a plurality of power nodes, and classifies power nodes as main power candidates, auxiliary power candidates, short-time supply candidates, standby candidates, or exclusion candidates by comparing the scheduled supply end time or the required supply time with the withdrawal scheduled time information.

[0003] Furthermore, the present invention excludes a power node whose withdrawal scheduled time is earlier than the scheduled supply end time, or a power node whose available time until the withdrawal scheduled time is less than the required supply time from the main power candidates, treats it as an auxiliary power candidate or a short-time supply candidate, and relates to a technology for generating a power allocation plan to a demand location or an important load facility based on the classification result.

Background Art

[0004] In the event of a disaster, a power outage, or a power supply-demand crunch, it is conceivable to supply power to shelters, hospitals, communication facilities, administrative bases, logistics bases, water supply facilities, and other important load facilities using electric vehicles, bidirectional charging / discharging devices, portable batteries, mobile bodies with generators, and other distributed power sources.

[0005] In such a distributed power network, each power node is centrally controlled according to its remaining power, available output, connection status, communication status, connection point, load conditions, etc. The central control unit can monitor the status of multiple power nodes and perform output setting, connection control, shutdown control, switching control, or allocation control for each power node in order to maintain supply to critical loads.

[0006] On the other hand, when electric vehicles are used as distributed power sources, unlike fixed equipment, these electric vehicles may need to be moved at the convenience of the owner, user, or operations manager. For example, electric vehicles may leave their current power supply location at a predetermined time for reasons such as returning home, changing evacuation routes, business operations, medical transport, delivery services, moving to a charging station, or returning the vehicle.

[0007] Such disconnections of power nodes based on the convenience of the owner or operator differ in nature from disconnections caused by communication failure, malfunction, sudden disconnection, or insufficient remaining power. In other words, the scheduled time of such disconnections can sometimes be known in advance, and by using that scheduled time, the network can not only control disconnections during supply but also make allocation decisions before supply begins.

[0008] However, conventional distributed power network control primarily selects power nodes based on factors such as the available output, remaining power, current location, or reachability of the power node. The configuration has not always adequately considered whether the power node is scheduled to exit at a predetermined time in the future before assigning it to a demand point or critical load equipment.

[0009] Therefore, for example, if a power node is scheduled to be decommissioned in a short time but is assigned as the main power source for critical load equipment that requires long-term supply, the power node may be decommissioned midway through the supply cycle, potentially leading to an unstable power supply to the critical load.

[0010] Furthermore, even power nodes with an approaching scheduled decommissioning time may be useful for short-term auxiliary power supply, temporary output support during startup, or bridging power supply until switching to another power node. Therefore, rather than excluding all power supply candidates simply because the scheduled decommissioning time is before the scheduled end of supply, it may be desirable to exclude them from being primary power supply candidates while making them available as auxiliary power supply candidates or short-term supply candidates.

[0011] Therefore, when a power node such as an electric vehicle has information on its scheduled exit time, there is a need for a technology that compares the scheduled supply end time, required supply time, and scheduled exit time information before allocating it to a demand point or critical load equipment, classifies the power node as a primary power source candidate, auxiliary power source candidate, or short-term supply candidate, and generates a power allocation plan based on the classification result.

[0013] The present invention has been made in view of the above circumstances, and aims to provide a distributed power node supply role determination technology that can reflect the scheduled departure time information in power allocation control before the start of supply when a power node is to leave the distributed power network at a predetermined time in the future based on the will or schedule of the owner, user, or operations manager.

[0014] Furthermore, the present invention aims to provide a distributed power node supply role determination technology that can exclude power nodes whose scheduled exit time is earlier than the scheduled end time of supply to demand points or critical load equipment, or whose available time until the scheduled exit time is less than the required supply time, from the main power source candidates and classify them as auxiliary power source candidates or short-term supply candidates.

[0015] Furthermore, the present invention aims to provide a distributed power node supply role determination technology that can calculate the amount of power that can be supplied for a short period of time based on the available time until the scheduled exit time, the available output, and the remaining power amount, and appropriately allocate power nodes that can be used as candidates for short-term supply to demand points or critical load equipment.

[0016] Furthermore, the present invention aims to provide a distributed power node supply role determination technology that can improve the continuity of supply to critical loads while effectively utilizing power nodes with scheduled exit times, by generating a power allocation plan based on the classification results of main power supply candidates, auxiliary power supply candidates, and short-term supply candidates, and including scheduled switching information to switch to an alternative power source before the scheduled exit time.

[0017] Furthermore, the present invention aims to provide a distributed power node supply role determination technology that can update the candidate classification of power nodes and the power allocation plan when there is a change or cancellation of the scheduled exit time information. [Means for solving the problem]

[0018] According to one aspect of the present invention, a distributed power node supply role determination system for determining the supply role of power nodes to be assigned to demand points or critical load equipment in a distributed power network having a plurality of power nodes, comprising a central control device.

[0019] The central control device includes a demand information acquisition unit that acquires demand information for the demand point or the important load equipment, including at least one of the required power, required amount of power, scheduled supply start time, scheduled supply end time, required supply time, and priority.

[0020] For each of the plurality of power nodes, the overall control device includes a node state acquisition unit that acquires node state information including at least one of a node identifier, available output, remaining power amount or SOC, connection state, communication state, connection point information, presence or absence of abnormality, and scheduled departure time information.

[0021] The overall control device includes an available time calculation unit that compares the scheduled supply end time or required supply time included in the demand information with the scheduled departure time indicated by the scheduled departure time information included in the node state information, and calculates the available time for each power node with respect to the demand location or the critical load facility.

[0022] The overall control device includes a main power supply candidate exclusion unit that excludes a power node whose scheduled departure time is earlier than the scheduled supply end time or a power node whose available time is less than the required supply time from the main power supply candidates for the demand location or the critical load facility.

[0023] The overall control device includes a candidate classification unit that classifies a power node excluded from the main power supply candidates as an auxiliary power supply candidate or a short-time supply candidate based on at least one of the available time, available output, remaining power amount or SOC, connection state, and communication state of the power node.

[0024] The overall control device includes a short-time supply available amount calculation unit that calculates the short-time supply available power amount of a power node classified as a short-time supply candidate based on at least one of the available time, available output, and remaining power amount or SOC.

[0025] The overall control device includes an allocation plan generation unit that generates a power allocation plan including the supply role of the power node to be allocated to the demand location or the critical load facility based on the classification results of the main power supply candidates, the auxiliary power supply candidates, and the short-time supply candidates.

[0031] The present invention can also be understood as a supply role determination method including the above functions, a program for causing a computer to execute the method, and a management device having the functions.

Advantages of the Invention

[0032] According to the present invention, before allocating power nodes to a demand point or important load equipment, the supply role can be determined in consideration of the scheduled exit time information of each power node.

[0033] Furthermore, according to the present invention, power nodes whose scheduled exit time is earlier than the scheduled supply end time, or power nodes whose available time until the scheduled exit time is less than the required supply time, can be excluded from the main power candidate list. This prevents the incorrect assignment of power nodes scheduled to exit in a short time to a main power source that requires long-term supply.

[0034] Furthermore, according to the present invention, even power nodes that have been excluded from the main power supply candidates can be classified as auxiliary power supply candidates or short-term supply candidates, and can therefore be effectively utilized in the short time until the scheduled exit time.

[0035] Furthermore, according to the present invention, since the amount of power that can be supplied for a short period of time from a candidate for short-term supply can be calculated, the power node can be appropriately used for auxiliary supply, startup support, peak load support, bridging supply until switching is complete, or temporary supply to non-priority loads.

[0036] Furthermore, according to the present invention, a power allocation plan can be generated that includes scheduled switching information for switching supply to another power node or an alternative power node before the scheduled exit time. This makes it possible to effectively utilize power nodes with scheduled exit times while improving the continuity of power supply to critical loads.

[0037] Furthermore, according to the present invention, candidate classifications and power allocation plans can be updated in response to changes or cancellations of scheduled exit time information, making it easier to maintain the supply stability of the distributed power network while responding to changes in the schedules of owners, users, or operations managers.

[0039] The embodiments for carrying out the present invention will be described below with reference to the drawings. The embodiments described below are examples to facilitate understanding of the present invention, and the present invention is not limited to these embodiments.

[0040] As shown in Figure 1, the distributed power node supply role determination system 10 according to this embodiment comprises a central control device 100, a communication network 200, a plurality of power nodes 300A, 300B, 300C, an owner information terminal 400, critical load equipment 500, and an operation management device 600.

[0041] The central control device 100 acquires status information and scheduled exit time information for power nodes 300A, 300B, and 300C in the distributed power network, and determines the power supply role of the power nodes to be assigned to critical load equipment 500.

[0042] The communication network 200 is a network that enables communication between the central control unit 100 and the power nodes 300A, 300B, 300C, the owner information terminal 400, and the operation management device 600.

[0043] Power nodes 300A, 300B, and 300C may be electric vehicles, bidirectional charge / discharge devices connected to said electric vehicles, portable batteries, mobile units with generators, fuel cell vehicles, power trailers, stationary batteries, or combinations thereof.

[0044] The owner information terminal 400 may be a terminal for the owner, user, or operations manager of a power node to input or transmit information regarding the scheduled departure time, the end of available use time, the scheduled departure time, the scheduled return time, or the scheduled departure time.

[0045] Critical load equipment 500 may include evacuation centers, hospitals, communication facilities, administrative centers, logistics centers, water supply facilities, public facilities, factories, shared facilities in apartment buildings, event venues, and other facilities that require power supply.

[0046] The operation management device 600 may be a device that manages the operation schedule, reservation schedule, return schedule, delivery schedule, or departure schedule of electric vehicles, delivery vehicles, business vehicles, rental cars, taxi vehicles, welfare vehicles, or disaster response vehicles.

[0047] As shown in Figure 2, the central control device 100 may include a demand information acquisition unit 101, a node status acquisition unit 102, an available time calculation unit 103, a main power supply candidate exclusion unit 104, a candidate classification unit 105, a short-time supplyable amount calculation unit 106, an allocation plan generation unit 107, an allocation plan update unit 108, a storage unit 109, and a communication unit 110.

[0048] The demand information acquisition unit 101 acquires demand information for important load equipment 500 or demand points, including at least one of the required power, required energy amount, scheduled supply start time, scheduled supply end time, required supply time, and priority.

[0049] The node status acquisition unit 102 acquires node status information for each of the multiple power nodes 300A, 300B, and 300C, which includes at least one of the following: node identifier, available output, remaining power or SOC, connection status, communication status, connection point information, presence or absence of abnormalities, and scheduled exit time information.

[0050] Exit schedule information indicates the time when an electric vehicle or mobile power source related to a power node is scheduled to leave the distributed power network based on the will or schedule of the owner, user, or operations manager. Exit schedule information may also be managed as departure schedule information, availability end time information, disconnection schedule information, departure schedule information, or return schedule information.

[0051] The available time calculation unit 103 compares the scheduled supply end time or required supply time included in the demand information with the scheduled exit time indicated by the scheduled exit time information included in the node status information, and calculates the available time for each power node for the critical load equipment 500.

[0052] The available time may be the time from the scheduled start time of service to the scheduled exit time, the time from the current time to the scheduled exit time, or the time from the scheduled exit time to the time obtained by subtracting the departure preparation time.

[0053] The main power supply candidate exclusion unit 104 excludes power nodes whose scheduled exit time is earlier than the scheduled supply end time, or power nodes whose available time until the scheduled exit time is less than the required supply time, from the main power supply candidates for the critical load equipment 500.

[0054] The candidate classification unit 105 classifies power nodes excluded from the main power supply candidates as auxiliary power supply candidates or short-term supply candidates based on at least one of the available time, available output, remaining power or SOC, connection status and communication status.

[0055] The candidate classification unit 105 may classify a power node as a short-term supply candidate even if the scheduled exit time is before the scheduled supply end time, provided that the available time until the scheduled exit time is equal to or greater than a predetermined time, and the available output or remaining power amount satisfies predetermined conditions.

[0056] The short-term supply capacity calculation unit 106 calculates the short-term supply capacity of power nodes classified as short-term supply candidates based on at least one of the available time, supplyable output, remaining power, or SOC.

[0057] The allocation plan generation unit 107 generates a power allocation plan, including the supply roles of power nodes to be allocated to critical load equipment 500, based on the classification results of main power supply candidates, auxiliary power supply candidates, and short-term supply candidates.

[0058] The power allocation plan may include at least one of the following: power node identifier, supply role, equipment to be supplied, scheduled start time of supply, scheduled end time of supply, scheduled power to be supplied, scheduled amount of power to be supplied, scheduled exit time, scheduled switchover time, and alternative power node identifier.

[0059] The allocation plan generation unit 107 may assign power nodes classified as short-time supply candidates to at least one of the following: auxiliary supply within a predetermined time, startup support, peak support, bridging supply until switching is complete, or temporary supply to non-priority loads.

[0060] The allocation plan generation unit 107 may generate a power allocation plan that includes scheduled switching information for switching the supply from a power node classified as a short-term supply candidate to another power node or an alternative power node before the scheduled exit time.

[0061] When the allocation plan update unit 108 obtains a change or cancellation of the scheduled exit time information, it updates at least one of the available time, candidate classification, short-term available power supply amount, and power supply allocation plan.

[0062] The memory unit 109 stores at least one of the following: demand information, node status information, scheduled exit time information, available time, candidate classification results, short-term supplyable power amount, power supply allocation plan, scheduled switching information, change history of scheduled exit time information, and allocation plan update history.

[0063] As shown in Figure 3, demand information may include a demand point identifier, a key load equipment identifier, required power, required energy amount, scheduled supply start time, scheduled supply end time, required supply duration, and priority. Node status information may include a node identifier, available output, remaining energy amount or SOC, connection status, communication status, connection point information, presence or absence of abnormalities, and scheduled exit time information.

[0064] As shown in Figure 4, the available time calculation unit 103 compares the scheduled supply period, from the scheduled supply start time to the scheduled supply end time, with the scheduled exit time of the power node. If the scheduled exit time is later than the scheduled supply end time, the power node may be treated as a primary power candidate. If the scheduled exit time is earlier than the scheduled supply end time, the power node is excluded from being a primary power candidate and may be treated as an auxiliary power candidate or a short-term supply candidate.

[0065] As shown in Figure 5, the candidate classification unit 105 classifies each power node into one of the following categories based on the scheduled exit time, available time, available output, and remaining power: main power candidate, auxiliary power candidate, short-term supply candidate, standby candidate, or exclusion candidate.

[0066] As shown in Figure 6, the short-term supply capacity calculation unit 106 calculates the amount of power that can be supplied for a short time for power nodes classified as short-term supply candidates, based on the available time and the available output. The amount of power that can be supplied for a short time may be capped based on the remaining power or the State of Charge (SOC).

[0067] As shown in Figure 7, the allocation plan generation unit 107 determines the supply role for each power node based on the classification results of main power supply candidates, auxiliary power supply candidates, and short-time supply candidates. For example, power nodes whose scheduled exit time is after the scheduled supply end time may be selected as main power supply candidates, and power nodes whose scheduled exit time is before the scheduled supply end time but have a short-time supply capacity may be assigned as short-time supply candidates.

[0068] As shown in Figure 8, the power allocation plan may include scheduled switching information to switch the supply from a power node classified as a short-term supply candidate to an alternative power node before the scheduled exit time of that power node.

[0069] As shown in Figure 9, if the scheduled exit time information is changed or canceled, the allocation plan update unit 108 recalculates the available time, updates the candidate classification, recalculates the short-term available power supply amount, and updates the power supply allocation plan.

[0070] As shown in Figure 10, the distributed power node supply role determination method first acquires demand information, then acquires node status information and scheduled exit time information, compares the scheduled supply end time or required supply time with the scheduled exit time to calculate the available time, and then performs the following: exclusion of main power candidate, classification into auxiliary power candidate or short-term supply candidate, calculation of short-term supplyable power amount, and generation of power allocation plan. [Examples]

[0071] The following describes embodiments of the present invention. In this embodiment, an example is taken in which a power node including multiple electric vehicles and portable storage batteries is assigned to a critical load facility 500 which is an evacuation center.

[0072] The scheduled start time for supplying critical load equipment 500 is 10:00, the scheduled end time is 16:00, and the required supply time is 6 hours. The required power is 10 kW, and the required energy volume is 60 kWh.

[0073] Power node 300A has a supply capacity of 10kW, a remaining energy capacity of 80kWh, and is scheduled to exit at 17:00. Power node 300B has a supply capacity of 8kW, a remaining energy capacity of 30kWh, and is scheduled to exit at 12:00. Power node 300C has a supply capacity of 6kW, a remaining energy capacity of 40kWh, and is scheduled to exit at 14:00.

[0074] The available time calculation unit 103 determines that for power node 300A, the scheduled exit time of 17:00 is later than the scheduled supply end time of 16:00, and therefore, it has available time that satisfies the required supply time.

[0075] The main power supply candidate exclusion unit 104 retains power node 300A as a main power supply candidate.

[0076] On the other hand, for power node 300B, since its scheduled exit time of 12:00 is before the scheduled end time of supply at 16:00, the main power candidate exclusion unit 104 excludes power node 300B from the main power candidate list.

[0077] The candidate classification unit 105 classifies power node 300B as a short-term supply candidate based on the fact that it has a two-hour availability period from 10:00 to 12:00, that its supplyable output is 8kW, and that its communication status is normal.

[0078] The short-term supply capacity calculation unit 106 calculates the short-term supply capacity for power node 300B as 16kWh, based on the available time of 2 hours and the supplyable output of 8kW. However, if the upper limit is restricted by the remaining power or SOC, the short-term supply capacity is calculated taking that upper limit into consideration.

[0079] Regarding power node 300C, since its scheduled exit time of 14:00 is before the scheduled end time of supply at 16:00, the main power candidate exclusion unit 104 excludes power node 300C from the main power candidate list.

[0080] The candidate classification unit 105 classifies power node 300C as an auxiliary power supply candidate or a short-term supply candidate based on the fact that it has a 4-hour available period from 10:00 to 14:00.

[0081] The allocation plan generation unit 107 generates a power allocation plan that allocates power node 300A as the main power source, power node 300B as a short-term power supply from 10:00 to 12:00, and power node 300C as an auxiliary power source.

[0082] The allocation plan generation unit 107 includes scheduled switching information in the power allocation plan to switch the power supply from power node 300B to power node 300C or another alternative power node before the scheduled exit time of power node 300B, 12:00.

[0083] Subsequently, if the owner of power node 300B changes their planned departure time from 12:00 to 15:00, the allocation plan update unit 108 recalculates the available time for power node 300B and updates the candidate classification and power allocation plan.

[0084] Furthermore, if the scheduled departure of power node 300B is canceled, the allocation plan update unit 108 determines whether power node 300B can be reclassified as a main power candidate and updates the power allocation plan as necessary.

[0085] This prevents the erroneous assignment of power nodes whose scheduled exit time is earlier than the scheduled supply end time as the primary power source, while allowing those power nodes to be effectively utilized as short-term supply candidates or auxiliary power source candidates. [Industrial applicability]

[0086] The present invention can be used in a distributed power network that supplies power to critical load equipment using electric vehicles, portable batteries, mobile units with generators, and other distributed power sources during disasters, power outages, or periods of tight power supply.

[0087] Furthermore, the present invention can be used to determine the supply role when utilizing electric vehicles, delivery vehicles, rental cars, taxi vehicles, commercial vehicles, welfare vehicles, disaster response vehicles, and other mobile power sources as power supply sources, taking into account the scheduled departure time, scheduled departure time, scheduled return time, scheduled end time of use, or scheduled departure time of the mobile power source.

[0088] Furthermore, the present invention can be used for generating power allocation plans, pre-allocating, short-term supply, auxiliary supply, bridging supply, scheduled switching, and updating allocation plans for evacuation centers, hospitals, communication facilities, administrative centers, logistics centers, water supply facilities, public facilities, factories, shared facilities in apartment buildings, event venues, and other critical load facilities.

[0089] Furthermore, since the present invention can record information on the scheduled exit time of power nodes, candidate classification results, short-term supplyable power amount, power allocation plan, scheduled switching information, and allocation plan update history, it can be used for post-event verification, auditing, settlement, fault analysis, evidence preservation, and operational improvement.
