A day-ahead optimal scheduling method for combined cooling heating and power(CCHP)multi-microgrid system considering energy storage station service is proposed. Firstly, the public energy storage station is built in the multi-microgrid system, and the service mode for the energy storage station on the user side is proposed. Then, the energy storage station service is applied to the optimal economic schedule of CCHP multi-microgrid system. The power balance and operation cost of the cooling load, heating load and power load in microgrids are optimized by coordinating the interactive power between energy storage station and microgrids. Finally, three operation modes of CCHP multi-microgrid system under the typical scenarios are carried out to analyze the optimal economic scheduling. Numerical studies demonstrate that the proposed optimal scheduling method can effectively improve the operation flexibility of the public energy storage station, realize time-domain transfer of the excess energy of microgrids and consume the renewable energy generation by 100%, while reduce the operation costs of CCHP multi-microgrid system.
