Research on Economic Dispatching Method of Active Distribution Network based on Multi-microgrids

With the addition of more high-performing new energy power generation, the lack of multi-microgrids dispatch plan will severely limit the potential for new energy sources to be dissipated. This paper proposes a hierarchical scheduling structure for multiple interconnected microgrids, the upper level coordination scheduling center mainly considers the energy interaction between the distribution network scheduling plan and the whole interconnected microgrids response, the lower level coordination scheduling is to ensure the optimal operation of each microgrid while considering the energy interaction between microgrids. The energy exchange within the multi interconnected microgrids is realized according to the contact line plan. With this scheduling, the problem of oversize information exchange is improved in the original scheduling mode.
