Power trading management apparatus and power trading system

A power trading system in which a power supply apparatus which supplies power, a power demand apparatus which requests power, a power storage and discharge apparatus which stores and discharges power, and a power transmission switching apparatus which switches a power transmission path between the power supply apparatus, the power demand apparatus, and the power storage and discharge apparatus are connected via a power network and that includes a supply-side computer which controls the power supply apparatus, a demand-side computer which controls the power demand apparatus, and a power trading management apparatus connected so as to be able to communicate with the power transmission switching apparatus, the supply-side computer, the demand-side computer, and the power transmission switching apparatus via a communication network, wherein

• the power trading management apparatus includes a processor that executes a program and a storage device that stores the program,
• the processor executes
• reception processing of receiving power supply application data including an amount of supplied power and a supply period from the supply-side computer, and receiving power demand application data including an amount of requested power and a request period from the demand-side computer,
• determination processing of determining whether or not a first trading condition in which the supply period is a period earlier than the request period is satisfied,
• decision processing of deciding an amount of transmitted power for the power demand apparatus based on at least any one amount of power of the amount of supplied power and the amount of requested power when it is determined that the first trading condition is satisfied by the determination processing, and
• power transmission control processing of storing the amount of supplied power in the power storage and discharge apparatus from the power supply apparatus in the supply period and discharging the amount of transmitted power decided by the decision processing to the power demand apparatus from the power storage and discharge apparatus in the request period by controlling the power transmission switching apparatus,
• wherein the power supply apparatus is connected so as to able to transmit power to a first power storage and discharge apparatus via a first power transmission switching apparatus, the power demand apparatus is connected so as to be able to transmit power from a second power storage and discharge apparatus via a second power transmission switching apparatus, and the first power transmission switching apparatus and the second power transmission switching apparatus are connected so as to be able to transmit power, and
• wherein in the power transmission control processing, the processor stores the amount of supplied power in the first power storage and discharge apparatus via the first power transmission switching apparatus from the power supply apparatus in the supply period, transmits the amount of supplied power to the second power storage and discharge apparatus from the first power storage and discharge apparatus after the supply period elapses and before the request period is started, and discharges the amount of transmitted power to the power demand apparatus from the second power storage and discharge apparatus via the second power transmission switching apparatus in the request period by controlling the first power transmission switching apparatus and the second power transmission switching apparatus.
