A power management server comprises a controller configured to select based on a predetermined standard, from among a plurality of facilities including a distributed power supply, a first facility in which first processing is applied to the distributed power supply and a second facility in which second processing is applied to the distributed power supply. The first processing is processing of controlling an output power of the distributed power supply by using a first target value as a target value for purchased power purchased by the facility from a power provider. The second processing is processing of controlling the output power of the distributed power supply by using a second target value as the target value for the purchased power, the second target value being greater than the first target value.

A power management apparatus includes a receiver configured to receive measurement information obtained by measuring a power of a facility connected to a power grid; and a transmitter configured to transmit a power control message. The transmitter transmits the power control message based on an output power amount of a distributed power supply provided in the facility, in addition to the measurement information. The measurement information is information indicating a total power flow amount from the power grid to the facility or a total reverse power flow amount from the facility to the power grid. The distributed power supply is a power supply that allows a reverse power flow from the facility to the power grid.

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

A power management method comprises: a step A of transmitting a first message from a power management server to a local control apparatus according to a first protocol, the power management server managing a facility connected to a power grid, the local control apparatus provided in the facility; a step B of transmitting a second message from the local control apparatus to the equipment according to a second protocol different from the first protocol; and a step C of transmitting a third message from the local control apparatus to the power management server according to the first protocol, the third message including specification information specifying a local control element which the equipment is capable of dealing with according to the second protocol. The specification information includes information specifying whether or not the equipment deals with a local control element indicating an operation state requesting setting for the equipment.

Power management method, local control apparatus and power management system

A management method includes a step A of estimating, for each of the plurality of entities, an error pattern related to a prediction error occurring when a power consumption amount in a future period is predicted; and a step B of determining a group of entities from among the plurality of entities based on the error pattern, wherein the group is a destination of a power reduction request for reducing the power consumption amount. The step A includes a step of estimating whether the prediction error is a positive error or a negative error. The step B includes a step of determining the group such that a total prediction error of the group is minimized, by combining an entity of which the prediction error is estimated to be a positive error and an entity of which the prediction error is estimated to be a negative error.

Management method and management apparatus

A power management method includes a step A of transmitting a first message from a power management server to a local control apparatus according to a first protocol, and a step B of transmitting a second message from the local control apparatus to an equipment according to a second protocol different from the first protocol. The second message corresponds to control content for the equipment instructed by the first message and includes an information element of the second protocol corresponding to an information element of the first protocol.
