Abstract

To improve the economic benefits and operational flexibility of the integrated energy system, the complex operation mechanism of integrated energy is studied and analyzed from three levels of “generation, storage and load”, then a scheduling model of integrated energy system including concentrating solar power station, power to gas and controllable load is built. Firstly, an electric-coupled photothermal power station is proposed to realize the integration of electric-thermal energy conversion and thermal energy storage. Secondly, the double-layer energy optimization control strategy of power to hydrogen and power to gas is established, which provides a new way for renewable energy storage and dissipation. Finally, comprehensively consider the impact of electric load demand response and thermal flexible load to ensure power supply. Based on the actual data of an industrial park in Inner Mongolia, the feasibility of scheduling is verified under multi scenario and multi energy configuration. The simulation results show that the proposed model can reduce operating costs and reduce CO₂ emissions effectively, which further realize coordinated dispatching of integrated energy system.
