Abstract: In view of the promotion of clean energy mechanism and the continuous development of combined cooling heating and power (CCHP), an economic dispatching model considering both demand side response and power interaction among multi-microgrids was proposed, meanwhile following items such as the gas cost, the operation and maintenance cost for wind and photovoltaic power generation, the operation cost for storage battery, the cost and revenue being taken place by the electricity purchasing and selling due to the power interaction among microgrids and large power grid were synthetically considered. Finally, in accordance with typical dispatching days the economic dispatching model for multi-microgrids was simulated. Simulation results show that utilizing the proposed dispatch model, the power consumption of various new energy sources can be obviously increased.
