At present, the coupling of natural gas network, thermal network and power network in the active distribution network has been deepened to jointly provide users with cold, hot, electric, gas and other forms of energy, but the relevant coordination control technology is still immature. This paper takes the power grid as the core and conducts interactive optimization with the heat and natural gas networks. Firstly, it puts forward a comprehensive modeling method including the power network, natural gas network and thermal network, and comprehensively optimizes the constraint conditions and operational objectives of multi-energy flow of each energy subsystem, so as to realize the coordination and complementarity of multi-energy and in-depth integration. Then, a hierarchical distributed coordinated control strategy is designed for the stable operation of multi-micro grid and active distribution network. The system can be divided into the active layer, the interconnected microgrid layer, and the component layer, in which the improved secondary power optimization control for the coordination is proposed between the distributed equipment control. Finally, PSCAD/EMTDC simulation software is used to build a simulation platform for active distribution network, which includes three energy interconnection microgrids, to prove the rationality of intelligent control method.
