Abstract: In the plan control, the control right of HEMS is held by the energy management server 2, and HEMS is controlled based on a power supply and demand plan developed in advance. The edge-control is such that HEMS controllers has a control right of HEMS and control HEMS based on the actual status of HEMS surplus power and power demand. HEMS includes an electrified vehicle (storage battery). The energy management server 2 switches the power management control from the edge control to the planning control when it is predicted that the actual SOC of electrified vehicle 12 is insufficient for the target SOC at the scheduled departure time of electrified vehicle during the execution of the edge control.

Abstract: An electricity management apparatus (an aggregator server, an electricity generation business operator server) is an apparatus that manages adjustment power of electricity delivered to an electricity transmission and distribution business operator by a trading business operator (an aggregator, an electricity generation business operator).

Abstract: A power management system includes a plurality of power adjustment resources electrically connected to a microgrid MG, and a CEMS server that manages the power adjustment resources. The CEMS server outputs a power adjustment request to the power adjustment resources when suppression of power consumption or consumption of surplus power in the microgrid MG is requested, and gives an incentive to a “responding resource” as the power adjustment resource that performs power adjustment in response to the power adjustment request among the power adjustment resources. The CEMS server increases the incentive more as a deviation of a time period during which the power adjustment is performed by the responding resource, with respect to a time period determined in the power adjustment request is smaller.
