Distributed electricity storage system, power control method, and program

A power control method executed in a distributed electricity storage system comprising a plurality of electricity storage apparatuses connected to a same distribution line, the method performed by a computer included in the distributed electricity storage system comprising:

• determining excess or deficient power in the distribution line;
• acquiring, with respect to each of the plurality of electricity storage apparatuses, state information indicating a state of an electricity storage apparatus and direction information indicating an operating direction of a charging direction or a discharging direction;
• and
• selecting an electricity storage apparatus to be controlled in charging and discharging operations from the plurality of electricity storage apparatuses, using a determination result of the excess or deficient power, the state information, and the direction information.
