Optimal Dispatch of Park-level Integrated Energy System with Flexible Loads and Equipment Variable Operating Conditions

In order to fully exploit the advantages of the park-level integrated energy system, economic optimization and dispatch of the system are essential. The economic scheduling of the park-level integrated energy system considering flexible loads and variable operating conditions of energy conversion equipment is studied. Firstly, the load side is analyzed, and the consideration of flexible loads in the economic scheduling of the integrated energy system in industrial parks can better utilize the adjustable characteristics of flexible loads and achieve the goal of saving total cost. Secondly, the device side is analyzed, and a modeling approach for the variable operating conditions of energy conversion equipment is proposed, considering that the variable operating conditions of energy conversion equipment can improve the coordination among the devices in the integrated energy system and make it operate at a suitable operating condition. Finally, the applicability and economic benefits of the proposed method are demonstrated through experiments.
