A CEMS server manages an amount of demanded electric power of consumer facilities organized into groups. The groups include at least two consumer facilities of which amounts of demanded electric power are correlated with each other. One of the at least two consumer facilities includes an HEMS server that transmits an amount of demanded electric power of the corresponding consumer facility to the CEMS server every first period. The CEMS server stores relationship information indicating a relationship between the amounts of demanded electric power of the at least two consumer facilities. The CEMS server calculates a total amount of demanded electric power of the groups based on the amount of demanded electric power transmitted from the HEMS server and the relationship information and outputs a DR request to the consumer facilities such that the total amount of demanded electric power matches a planned amount of electric power.

Management server and management method

A vehicle diagnosis method includes a) determining, when a subject vehicle including a power storage enters a chargeable state in which it can receive power feed from EVSE, whether or not charging of the power storage is started in the subject vehicle, b) determining whether or not timer-programmed charging has been set in the subject vehicle that has entered the chargeable state, and c) determining whether or not charging and discharging control of the power storage is being carried out in the subject vehicle under remote control based on a determination result in at least one of a) determining and b) determining.

Server, vehicle, and vehicle diagnosis method

A power management system includes a first server configured to manage electric vehicle supply equipment in a microgrid and a second server configured to manage power supply and demand balance of a power system. The electric vehicle supply equipment is configured to execute a charging and discharging operation that suppresses a voltage fluctuation of the microgrid by exchanging power between the microgrid and a vehicle, and a reactive power compensation operation that suppresses a voltage fluctuation of the power system by controlling reactive power of the microgrid.

Power management system, electric vehicle supply equipment, server, and adjustment method of power supply and demand balance

A power management system includes a photovoltaic power generator connected to a power network, an energy storage device configured to be connected to the power network, and a server. The server is configured to: acquire a predicted value of solar radiation at a prediction time at a point where the photovoltaic power generator is installed; calculate a predicted value of power generated by the photovoltaic power generator at the prediction time by using the predicted value of solar radiation; set a target range of an SOC of the energy storage device by using the predicted value, and control the SOC in such a way that the SOC falls within the target range by the prediction time; and set the target range to a wider range when reliability of the predicted value is low than when the reliability of the predicted value is high.

Power management system, power management server, and power management method

A power management system includes a CEMS server that outputs a DR request to a plurality of power adjustment resources such that balancing is achieved every prescribed time period. The plurality of power adjustment resources include: a power-storage-type DER that stores the supply power in an energy form of at least one of electricity, heat and gas fuel; and a consumption-type DER that consumes the supply power by at least one of air conditioning and lighting. In a case where it is expected in the middle of the prescribed time period that the actual amount of power exceeds the planned amount of power at the end of the prescribed time period, the CEMS server outputs, to the power-storage-type DER more preferentially than to the consumption-type DER, the DR request for decreasing the actual amount of power in comparison with before expectation.

Power management system, server, and power supply and demand adjustment

In a server, an acquisition unit obtains, from a vehicle through a communication apparatus, history information indicating that demand and supply of electric power has been performed for a power grid PG, and information on the state of charge of a battery. A control unit determines priorities of a plurality of DERs for a DR request. The control unit determines a priority of the vehicle so that the vehicle is less likely to be selected for the DR request, when the SOC obtained by the acquisition unit has changed although the acquisition unit has not received the history information.

Power management apparatus and power management method

A server that manages a plurality of power adjustment resources electrically connectable to a power network includes a determination unit and a first permission unit. The determination unit determines, before a vehicle including a power storage starts charging of the power storage by using the power network, whether or not electric power corresponding to charging power can be supplied to the power network by having at least one of the power adjustment resources respond to the charging of the power storage. When the determination unit determines that electric power can be supplied, the first permission unit permits supply of electric power from the power network to the vehicle.

Server and power management method

Before start of vehicle charging by using a power network, a first determination unit determines whether reserve of the power network is not less than a first reference value. When reserve of the power network is not less than the first reference value, a first permission unit permits supply of electric power from the power network to a vehicle. When reserve of the power network is smaller than the first reference value, a second determination unit determines whether or not electric power corresponding to charging power can be supplied to the power network by having at least one of power adjustment resources respond to vehicle charging. When the second determination unit determines that electric power can be supplied, a second permission unit permits supply of electric power from the power network to the vehicle.

A power management system includes a plurality of power storages and a server. The server includes a selector that selects at least one of the plurality of power storages, a scheduler that makes a schedule for the selected power storage, and a request processor that requests a user of the selected power storage to control at least one of external charging and external power feed in accordance with the made schedule. The server obtains desire information that indicates a desire level (priority on battery life/priority on an incentive) and carries out at least one of selection of the power storage and making of the schedule based on the obtained desire information.

Power management system and server operable for selecting and scheduling power storages based on users desires

A first switching unit switches a first power grid from an isolated operation to a grid-connected operation. In switching the first power grid from the isolated operation to the grid-connected operation, the first switching unit determines a master and a slave among a plurality of power adjustment resources and allows the first power grid to be connected to the second power grid after master-slave control by means of the master and the slave such that electric power of the first power grid is in synchronization with electric power of the second power grid. The first switching unit preferentially selects as the master, a power adjustment resource close to a point of connection between the first power grid and the second power grid from among the plurality of power adjustment resources.

A power management system includes a plurality of power adjustment resources electrically connected to a microgrid. The plurality of power adjustment resources include a plurality of EVSEs, each of EVSEs including a parking space. When any one of a plurality of power feeding vehicles is parked in the parking space, an EVSE enables power feeding from a vehicle parked in the parking space to the microgrid. A CEMS server manages the parking space. When a balance of power supply and demand in the microgrid is in an overdemand state, the CEMS server allocates the parking space to a power feeding vehicle that responds to a request for power feeding to the microgrid, of the plurality of power feeding vehicles.

Power management system, server, and power supply and demand adjustment method

A power management system includes a plurality of power adjustment resources electrically connected to a microgrid, and a CEMS server that manages the plurality of power adjustment resources. The plurality of power adjustment resources include a plurality of FCEVs that supply electric power to the microgrid. Each of the plurality of FCEVs executes a refresh process that removes an oxide film formed on a catalyst electrode of an FC stack by causing the FC stack to generate electric power exceeding prescribed electric power. The CEMS server adjusts execution timings of the refresh process in the plurality of FCEVs during power supply to the microgrid, so as to respond to a request to adjust power supply and demand in the microgrid.

When a baseline is in a certain state, a server executes a process including: a step of calculating an amount of power exchanged between a battery and a power grid during the first charging control; a step of calculating an amount of power exchanged between the battery and the power grid during the second charging control; a step of calculating an amount of power exchanged between the battery and the power grid during the first power feeding control; a step of calculating an amount of power exchanged between the battery and the power grid during the second power feeding control; and a step of setting a calibration line for the amount of power.

Power amount measurement system, power amount measurement method, and power amount measurement device

In switching of a microgrid from an isolated operation to an interconnected operation with a power grid, a CEMS server determines a first master DER and slaves based on a master plan and performs master-slave control. When the first master DER goes down, the CEMS server compares remaining capacities of power-storage-type DERs included in a DER group. The CEMS server then determines a DER with the highest remaining capacity as a second master DER among the power-storage-type DERs included in the DER group and performs master-slave control.

Electric power system and server

A controller in a vehicle includes an obtaining unit that obtains facility information on a charging facility that can charge a power storage mounted on the vehicle, the facility information including position information and utility information in association with each other, the position information indicating a position of the charging facility, the utility information indicating an electric utility that manages the charging facility. The controller further includes at least one of a first notification unit and a second notification unit. The first notification unit causes a notification apparatus to give first information that indicates an electric utility, by using the facility information obtained by the obtaining unit. The second notification unit causes the notification apparatus to give second information that indicates a position of a charging facility, by using the facility information obtained by the obtaining unit.
