摘要
The photovoltaic (PV) power surges with varied with sunlight intensity and temperature, resulting in great fluctuation of power on the side of synchronization on AC busbar micro-grid. Configuring an energy storage system may allow that the grid output is fallen into a specified interval for the purpose of reduction in grid transmission capacity. The energy conversion device of the energy storage system is designed with two stages. The inverter control strategy includes PQ control mode, VF control mode and constant-voltage charging/discharging mode on the battery side. The chopper control strategy uses control DC busbar voltage stability mode. The reliability of control strategies is verified by simulation, which are able to quickly follow up instruction change and suppress disturbance.
