ELECTRICITYPROVIDING SYSTEM INCLUDING BATTERY ENERGY STORAGE SYSTEM

摘要

A power supply system is disclosed. The power supply system includes a power generating device which generates electric energy; a plurality of DC/AC convertors which convert the electric energy into AC; a battery energy storage system which receives the electric energy to charge, discharges the charged electric energy, and supplies the electric energy to the plurality of DC/AC convertors; and a control switch which controls the flow of power supply between the battery energy storage system and the power generating device. So, power supplied to the plurality of DC/AC convertors can be efficiently controlled.
