THE COORDINATED CONTROL SYSTEM AND METHOD OF ENERGY STORAGE DEVICE

摘要

PURPOSE: A coordinate control system and method of an energy storage device for microgrid are provided to implement stable operation by constantly maintaining system power. CONSTITUTION: A first energy storage device(200) has an SOC function. A second energy storage device(300) does not have the SOC function. A central control device(400) receives a current output value of the first and second storage devices. The central control device receives a current output value of each distributed power(100). A load amount calculator calculates a load amount of a microgrid system by adding the current output values. [Reference numerals] (100) Distributed power 1-n; (200) First energy storage device; (300) Second energy storage device; (400) Central control device; (600) Stationary switchgear; (800) Load; (AA) Transformer for power distribution
