In view of the problem of wind abandonment during the heating period in the northern China

a comprehensive electricity-heat energy system with horizontal electricity-heat complementation and longitudinal Source-Network-Storage is set up on the basis of the traditional electricity-heat combined system.The system fully considers the thermal dynamic characteristics of the heat supply network and such two types of energy storage devices as power storage and heat storage. In case of meeting the electricity and heat requirements

the optimal operation model with the minimum operation cost as objective is set up. The model is solved by calling YALMIP toolbox and CPLEX solver in Matlab. The thermal dynamic characteristics of the heat supply network and the influence of the energy storage device on the system operating cost and the amount of abandoned wind are analyzed through simulation of example. The impact of energy storage investment cost on the system under different energy storage configurations is also discussed and rationality of the model is verified.
