Optimized scheduling of heating network transmission delay and heat storage can improve the flexibility of the electricity-heat integrated energy system, while achieving economic operation of the system, further improving the system"s new energy consumption. In this paper, day-ahead optimal scheduling strategy of electric-heat integrated energy system is proposed considering transmission delay and heat storage of heating network. Firstly, a heating system model describing the transmission delay and heat storage of the heating network is established. Then combined with the energy equipment model, the heating network is used as a scheduling resource to participate in the day-ahead optimal scheduling, and a day-ahead scheduling model considering the heating system is proposed to realize the scheduling and utilization of the virtual energy storage in the heating network. Finally, a typical example is given to verify the effectiveness of the proposed method. The calculation results show that the method can further reduce the operating cost of the system and improve the absorption rate of wind power by using the transmission delay and heat storage of heating network..
