COOPERATED CONTROL METHOD AND SYSTEM FOR DISTRIBUTED BATTERY ENERGY STORAGE SYSTEMS

摘要

A cooperated control system for distributed battery energy storage systems (BESS) according to embodiments of the present invention comprises: a cooperated control server which receives measurement data including magnitude of voltage, frequency, phase angle, magnitude of load from sensors installed in a distribution system, receives charge state data from each of the BESS constituting a battery energy storage system group, determines whether disturbance of the distribution system occurs on the basis of the measured measurement data, and transmits a charge control signal or a discharge control signal to a priority BESS of each BESS group to suppress disturbance occurring in the distribution system when the disturbance occurs; and at least one battery energy storage system which performs one of a charge operation, a discharge operation, or a system separation operation on the basis of the charge state of the secondary battery while sequentially receiving the charge control signal or the discharge control signal in accordance with the given priority in each BESS group.;COPYRIGHT KIPO 2016
