At present, the thermal network and electrical network in regional energy network are intensifying their coupling, and provide users with different forms of energy such as cold, heat and electricity. However, the relevant coordinated control technologies are still immature. Considering the advantages and disadvantages and their complementary characteristics of different energy sources, a hierarchical and distributed collaborative optimization control structure is proposed. The structure centers on the power grid and collaborate optimization and interconnection with thermal network, at the same time, it draws on the idea of information and data interconnection, integrates energy into network, and matches corresponding communication means to achieve multi-energy coordination, complementarity and deep integration. Finally, through PSCAD/EMTDC simulation platform, a regional energy network model considering the electric-thermal coupling characteristics is bulit to verify the effectiveness of the proposed control strategy.
