下垂控制下的微电源并入和退出运行策略
Connecting and Disconnecting Strategies for Micro Generation Based on Droop Control
摘要
Abstract
To achieve the function of“plug and play”and power-sharing in micro grid,the connecting and disconnect⁃ing processes of micro generations to the micro grid are studied. The theory of circulation current which is caused by mi⁃cro generations is analyzed in detail. By using secondary frequency modulation,the circulation power is eliminated ef⁃fectively,and the recovery time to steady state is also reduced. At the same time,different situations when the micro generations are disconnected to the micro grid are discussed. In the case of overload,the strategy of using both primary and secondary frequency modulations is proposed to cut off the loads according to their levels to avoid overloading, which can keep the frequency of micro grid stable. At last,the rationality and feasibility of these strategies are proved by simulation using MATALAB/Simulink.关键词
