SYSTEM AND METHOD FOR ESTIMATING BATTERY CAPACITY OF MICROGRID

摘要

PURPOSE: A system and method for estimating the capacity of a microgrid energy storage device are provided to stably and economically operate a system. CONSTITUTION: A micro grid system unit(100) includes one or more distribution power sources and supplies power to a micro grid load. An operation plan system unit(200) calculates the optimum output condition of the distribution power source and calculates the capacity of an energy storage device. An energy managing system unit(400) controls the distribution power source and the energy storage device according to the capacity of the energy storage device and the optimum output condition of the distribution power source.
