Power supply and demand management device, power supply and demand management system, and power supply and demand management method

摘要

PROBLEM TO BE SOLVED: To provide a power supply and demand management device, a power supply and demand management system, and a power supply and demand management method capable of avoiding a penalty due to the occurrence of imbalance. SOLUTION: In the electric power supply and demand management system 1, the electric power supply and demand management device 20 can be generated within the bidding unit time based on the bid electric energy, the current electric power value, and the predicted electric power value after the bidding unit time. The imbalance amount calculation unit 24 that calculates the imbalance amount, the control amount calculation unit 26 that calculates the control amount required to make the imbalance amount calculated by the imbalance amount calculation unit zero, and the control amount calculation unit. A control unit 27 that transmits the control amount calculated in 1 to the device is provided. [Selection diagram] Fig. 1
