In order to increase the rate of renewable energy accommodation and reduce the environmental pollution caused by carbon emissions during power generation, an optimal dispatch model considering heating network constraints and carbon trading for the multi-region integrated energy systems is proposed. Firstly, a model is established to couple the regional integrated energy system and the heating network with basic equations to represent the heat-supply pipelines and nodes in the heating network system. Secondly, by analyzing the characteristics of two domestic and foreign carbon trading mechanisms, a low-carbon economic dispatch model is established, in which the objective function is to minimize the sum of system operation cost, carbon trading cost and the penalty cost relevant to the renewable energy accommodation. Finally, a mixed integer linear programming is used to solve the problem of a multi-region integrated energy system interconnected with a heating network in winter, and the effects of two carbon trading mechanisms on the economic operation and carbon emissions of the system are analyzed. The results show that the multi-region integrated energy system connected with a heating network can reduce the system carbon emissions and increase the rate of renewable energy accommodation by fully utilizing the complementary characteristics of inter-region loads.
