CONTROL SYSTEM FOR ELECTRIC STORAGE SYSTEM

摘要

A control system for an electric storage system, in which a plurality of pairs of storage batteries and converters are connected in parallel to a power system, includes: a unit that decides charge and discharge of total power by the pairs of storage batteries and converters; and a unit that distributes the charge and discharge power decided by the charge and discharge power decision unit to the pairs of storage batteries and converters. The power distribution decision unit compares the charge and discharge total power with a limit output when conversion efficiency of the converters is equal to or greater than standard efficiency, and decides a running number by which an output of all the pairs of running storage batteries and converters is equal to or greater than the limit output when the charge and discharge total power is equal to or greater than the limit output.

1. A control system for an electric storage system in which a plurality of pairs of storage batteries and converters are connected in parallel to a power system, and which includes:
a charge and discharge total power decision unit that decides charge and discharge total power by the plurality of pairs of storage batteries and converters, and a power distribution decision unit that distributes the charge and discharge total power decided by the charge and discharge total power decision unit to the plurality of pairs of storage batteries and converters, the system comprising: causing the power distribution decision unit to compare the charge and discharge total power with limit output when conversion efficiency of the converters is equal to or greater than standard efficiency, and to decide an operation number by which an output of all the pairs of operating storage batteries and converters is equal to or greater than the limit output when the charge and discharge total power is equal to or greater than the limit output.
