There is a wind curtailment problem caused by the traditional Combined Heat and Power (CHP) operation mode of determining-power-by-heat. Thus a method of "source-network-load-storage" coordinated optimization operation for an integrated energy system considering wind power accommodation and operational economic benefits is proposed. A heat pump and energy storage equipment are added to the source side to decouple the determining-power-by-heat operation constraints of CHP. Also a steady-state electricity-heat flow is constructed on the network side and integrated demand response is considered on the load side to increase the wind power accommodation space of the system. The system aims to minimize the total cost and takes into account constraint conditions such as the energy balance, steady-state electricity-heat flow and CHP unit output. An integrated energy system "source-network-load-storage" optimized operation model is constructed considering wind power accommodation. Finally, an integrated energy system consisting of a 33-node network containing wind turbines and an 8-node heating network is used to verify the correctness and effectiveness of the proposed method. The results of multi-scenario simulation show that this method can effectively improve the accommodation space of wind power and the economic benefits of the system.
