摘要
An optimal scheduling method for integrated electro-thermal energy system considering heat transmission dynamic characteristics is proposed in this paper. Firstly, a quasi-dynamic model of heat transmission is proposed based on dynamic characteristics of heating network such as time delay and heat storage. The virtual storage potential of heating network is analyzed. Then, combined with energy equipment model, an optimal scheduling method considering heat transmission dynamic characteristics is proposed. The heating network is used as scheduling resource to participate in the optimal scheduling of integrated electro-thermal energy system. Scheduling of the virtual storage of heating network is thus achieved. Numerical studies demonstrate that the model considering heat transmission dynamic characteristics is able to reduce operational cost of integrated energy system by making use of the virtual storage inspired by time-of-use electricity prices as well as taking advantage of the complementarity between electrical and thermal power flow. © 2020, Power System Technology Press.
