In order to solve these issues that severe abandonment of wind and air pollution caused by coal combustion in North China during winter heating period, considering the forecast error of wind power and price elasticity of supply, a electric boiler pre-day optimal scheduling model based on terminal heat load characteristics is constructed by taking the minimum operation cost of the heating system as the optimization objective function and the operation economy of electric heating system with storage system for heating is analyzed under the background of electricity market. Through the introduction of heat storage device to make more reasonable use of the wind power curtailment in all periods, the operation economy of the heating system is further improved. In solving stage, branch and bound algorithm (BBA) based on CPLEX software is used to solve the model, and the effectiveness of the proposed method and model is verified by the simulation results of a certain example.
