摘要：

A distributed control strategy for Energy Storage Unit (ESU) in MicroGrid is presented in this paper. In the presence of the stochasticity of renewable generation and load demand, the power balance for MicroGrid should be guaranteed by employing real-time control of the charging/discharging power of ESU. A distributed gradient algorithm is firstly employed to construct the distributed power balance control, which is used to balance the active power in MicroGrid. The objective of the proposed control is minimizing the total active power loss during the charging/discharging process, with the linear relationship among charging/discharging efficiency, charging/discharging rate and State of Charge (SOC) considered. The simulation results demonstrate the effectiveness of the proposed method.
