Abstract:Based on the analysis of voltage-power characteristics of micro-grid with wind power and energy storage, an approach to suppress voltage fluctuation based on the super capacitor control strategy is proposed. It can quickly compensate for random fluctuations of wind power, ensuring the common power of wind power and super capacitor transmitted to the outside steady, thereby achieving the system bus voltage stability control. The PSCAD-based simulation of the proposed method is performed, and simulation results show that when wind speed changes, it can effectively suppress the voltage fluctuation caused by changes in wind power; when large resistive inductive loads are input or the external fault happens, it can also reduce the voltage fluctuation and voltage recovery time, which proves the proposed method is effective and feasible.
Keywords:micro-grid  wind power  voltage fluctuation  optimization control  super capacitor energy storage
