Optimal Scheduling Method for Electrical-Thermal Integrated Energy System Considering Heat Storage Characteristics of Heating Network

An optimal scheduling method for electrical-thermal integrated energy system considering heat storage characteristics of heating network is proposed in this paper. Firstly, a dynamic model of heat transmission considering time delay of heating network is proposed. The storage potential of heating network is analyzed. Then, combined with the energy equipment model, an optimal scheduling method for electrical-thermal integrated energy system considering heat storage characteristics of heating network is proposed. The heating network is used as the scheduling resource to participate in the optimal scheduling of electrical-thermal integrated energy system. Numerical studies demonstrate that the model considering time delay and heat storage is able to reduce operational cost of integrated energy system, and take advantage of the complementarity between electrical and thermal power flow.
