Abstract
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 promote external charging, suppress external charging, or carry out external power feed in accordance with the made schedule. The server obtains power run-out information that indicates power run-out risk for each power storage and carries out at least one of selection of the power storage and making of the schedule in accordance with a type of a request based on the obtained power run-out information.
Claims18
A server comprising a processor circuit and a memory, said server usable in a power management system including a plurality of power storages, each of the plurality of power storages carrying out at least one of external charging and external power feed, the external charging being charging of the power storage with electric power supplied from outside, the external power feed being supply of electric power from the power storage to outside, the server configured to:
- select at least one of the plurality of power storages;
- make a schedule for the selected power storage;
- request a user of the selected power storage to promote the external charging, suppress the external charging, or carry out the external power feed in accordance with the made schedule;
- obtain power run-out information that indicates power run-out risk for each power storage;
- carry out at least one of selection of the power storage and making of the schedule in accordance with a type of a request based on the obtained power run-out information;
- make a charging schedule such that the request is started earlier in a DR (demand response) vehicle higher in power run-out risk among selected DR vehicles;
- make a charging suppression schedule such that the request is started earlier in a DR vehicle lower in power run-out risk among selected DR vehicles;
- make a power feed schedule such that the request is started earlier in a DR vehicle lower in power run-out risk among selected DR vehicles;
- transmit the schedule for the DR vehicle to a user of the DR vehicle to request the user to give an answer as to whether or not the user approves the schedule;
- determine whether or not trading of electric power was done after all users have approved the schedule by the answer;
- and
- transmit a DR signal to each user that has approved the schedule when it is determined that the trading of electric power was done, the DR signal requesting the user of the DR vehicle to promote the external charging, suppress the external charging, or carry out the external power feed in accordance with the schedule.
A server comprising a processor and a memory, said server usable in a power management system including a plurality of power storages, each of the plurality of power storages carrying out at least one of external charging and external power feed, the external charging being charging of the power storage with electric power supplied from outside, the external power feed being supply of electric power from the power storage to outside, the plurality of power storages being mounted on a plurality of mobile bodies, respectively, the server configured to:
- select at least one of the plurality of power storages;
- make a schedule for the selected power storage;
- request a user of the selected power storage to promote the external charging, suppress the external charging, or carry out the external power feed in accordance with the made schedule;
- obtain information on at least one of long-distance travel capability, charging capability, a current position, a next travel distance, next departure time, a next travel route, and remaining energy for traveling for each mobile body;
- carry out at least one of selection of the power storage and making of the schedule in accordance with a type of a request based on the obtained information;
- make a charging schedule such that the request is started earlier in a DR (demand response) vehicle higher in power run-out risk among selected DR vehicles;
- make a charging suppression schedule such that the request is started earlier in a DR vehicle lower in power run-out risk among selected DR vehicles;
- make a power feed schedule such that the request is started earlier in a DR vehicle lower in power run-out risk among selected DR vehicles;
- transmit the schedule for the DR vehicle to a user of the DR vehicle to request the user to give an answer as to whether or not the user approves the schedule;
- determine whether or not trading of electric power was done after all users have approved the schedule by the answer;
- and
- transmit a DR signal to each user that has approved the schedule when it is determined that the trading of electric power was done, the DR signal requesting the user of the DR vehicle to promote the external charging, suppress the external charging, or carry out the external power feed in accordance with the schedule.
