Microgrid PCC Power Dispatch Strategy Based on Multi-ESS Control during Peak, Flat and Valley Periods

Due to the self-healing ability and energy storage of microgrid, it can not only improve stability of islanding operation, but also increase the economic when grid operates. This paper takes the PCC point power dispatch strategy as research objective, after analysis the structure and control strategy of microgrid, this paper develop the dispatch strategy of PCC point and put forward the multi-ess charge/discharge strategy based on wavelet packet decomposition, the multi-ess charge/discharge achieved by PQ control method. Finally, a numerical example verifies the correctness and effectiveness of the strategy.
