RELATED APPLICATIONS

The present application is a National Phase of International Application No. PCT/JP2017/039277, filed Oct. 31, 2017, and claims priority based on Japanese Patent Application No. 2016-212996, filed Oct. 31, 2016.

TECHNICAL FIELD

The present invention relates to a power management method, a local control apparatus and a power management system.

BACKGROUND ART

In recent years, in order to maintain a power supply and demand balance of a power grid, a technique for suppressing a power flow amount from the power grid to a facility or a reverse power flow amount from the facility to the power grid is known (for example, Patent Literatures 1 and 2). In addition, a system (hereinafter, referred to as Virtual Power Plant (VPP)) using distributed power supplies provided in a plurality of facilities as a power supply for supplying electric power to the power grid has attracted attention.

SUMMARY OF INVENTION

A power management method according to a first aspect 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.

A local control apparatus according to a second aspect comprises: a receiver configured to receive a first message from a power management server according to a first protocol, the power management server managing a facility connected to a power grid; and a transmitter configured to transmit a second message to an equipment according to a second protocol different from the first protocol, the equipment provided in the facility. The transmitter is configured to transmit a third message 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.

A power management system according to a third aspect comprises: a power management server configured to manage a facility connected to a power grid; and a local control apparatus provided in the facility. The power management server includes a first transmitter configured to transmit a first message to the local control apparatus according to a first protocol. The local control apparatus includes a second transmitter configured to transmit a second message to an equipment provided in the facility according to a second protocol different from the first protocol. The second transmitter is configured to transmit a third message 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.
