Optimal Dispatching of Combined Heat and Power System Considering the Power Demand Elasticity of Hydrogen Storage Active Load

With the wide application of hydrogen storage technology in the integrated energy system, the advantages of multienergy complementation on the load side are becoming obvious. In order to fully explore the elasticity of multienergy complementation to optimize system operation, this article incorporates hydrogen storage active load (HS-AL) into the combined heat and power system (CHPS) and analyzes its optimal operation mechanism. By analyzing the operating characteristics of hydrogen storage and the integrated demand response of terminal electric and thermal loads, the external demand elastic space of HS-AL is extracted. Then, the optimal dispatching model considering the power demand elasticity of HS-AL is established. Finally, the simulation validates the effectiveness of the proposed model. The results also show that the elasticity of HS-AL can be fully utilized to promote wind power accommodation and effectively reduce the deep regulation pressure of coal-fired power units at night. This research will provide a theoretical reference for the bidirectional coordinated optimization between HS-AL and CHPS.
