Abstract To realize the global optimization of the electricity and heat networks in the integrated energy system in the case of information privacy protection, this paper conducted the optimal coordinated operation of the photovoltaic (PV)-battery energy storage system (BESS)-combined heat and power (CHP) integrated energy system,and studied the feasibility of using decomposition and coordination to optimize the solution under the premise of privacy protection. Firstly, an overall optimal operation model of the coupled electricity-heat energy system was established. Secondly, Benders decomposition method was proposed to solve this model. The model was decomposed into the main problem of the thermal system and the sub-problem of the electrical system, the optimal power distribution of each system was obtained through the iterative calculation between two systems. Besides, the interactive mode of systems based on Benders decomposition method was studied. On the premise of ensuring the effective protection and isolation of the information of master problem and sub-problem as much as possible, two systems only exchange the privacy parameters and Benders cuts, to maximize the protection of the electrical/thermal system privacy. Finally, comparative analysis of three typical scenarios was used to validate this method.

Key words： Integrated energy system Benders decomposition information privacy protection optimal coordinated operation
