Optimal Operation Strategy of Integrated Energy System Considering Demand Response

Abstract

During the heating period of integrated energy systems, the heat-led mode operation of the heat and power association unit limits the peak shaving capacity of the system, resulting in high wind power abandonment rate and operation cost. An optimal operation strategy of integrated energy system considering demand response(DR) is proposed for solving this problem. Firstly, the electric boiler is introduced into the heat and power association system to realize the thermal power decoupling and optimize the heat and power association unit output. Secondly, an integrated DR model including reducible load and transferable load is established. Finally, considering the penalty cost of wind abandonment, a day ahead optimal operation strategy of heat and power association system with minimum operation cost as the objective is proposed. The simulation results demonstrate that the proposed strategy can improve the consumption rate of wind power and reduce the operation cost of the system effectively.
