Research on Secondary Frequency Control Strategy for Islanded Microgrid

[摘要] In view of the fact that the primary control has a steady-state frequency difference, this paper aims at the rapidity and economy of isolated microgrid frequency modulation, and proposes a secondary frequency control strategy for islanding microgrid based on distributed control. In order to verify the reliability of the strategy, the correctness and effectiveness of the proposed frequency modulation strategy were verified by Matlab/Simulink simulation analysis.
