With the maturity of distributed renewable energy generation technology and the market-oriented changes in China's energy sector, the optimized operation strategy of interconnected microgrids has attracted much attention. In this paper, the research on the optimal operation control strategy of the interconnected microgrid under the new power reform is carried out, and the double-sale electricity purchase optimization model of the interconnected microgrid in the power market is established. The lower level of the model is a distributed power generation dispatching model for the microgrid with its own maximum benefit. The upper level is an economic dispatching model that considers the distribution cost of the interconnected microgrid with the minimum total purchase cost of the system. The effectiveness of the proposed method is verified by simulation analysis of different operating modes and scenarios of interconnected microgrids.
