Abstract:
As having a charge/discharge control function of storage batteries, when a plurality of power conditioners having a same basic switching period are installed together, hunting of charging/discharging power of the storage battery connected to each power conditioner is suppressed. Execution periods of control processes performed by control units  14  of a plurality of power conditioners  10  that have a function of controlling charging and discharging of storage batteries  25  are changed from basic switching periods so as to be different from each other.

Claim (Index 1):
A power storage system including a plurality of power conditioners having the same basic switching period and connected to a power system and an alternating current (AC) load, wherein:\n each of the plurality of power conditioners comprises: a power conversion unit capable of supplying electric power from the power system to the AC load and/or a storage battery connected to the own power conditioner and supplying electric power charged to the storage battery together with electric power from the power system to the AC load or supplying only the electric power charged to the storage battery to the AC load; and a control unit configured to periodically perform a control process of controlling the power conversion unit so that a target amount of electric power is transmitted and received between the plurality of power conditioners and the power system based on a magnitude of an input/output current flowing between the plurality of power conditioners and the power system, wherein an execution period of the control process is able to be changed from the basic switching period, and wherein the execution periods of the control processes by the plurality of control units in the plurality of power conditioners are changed to be different from each other.
