Abstract:In order to optimize the regional comprehensive energy system, the battery, the thermal storage electric boiler and the power to gas ( P2G) equipment were added into the energy system. The impact of system operation was analyzed after adding different equipment. Then, the demand side response of the electric , heating, and gas were considered, and the economic operation model of regional comprehensive energy system of various energy storage equipment was established with the minimum operating cost of the system as the objective function. Seven scenarios were set up for comparative analysis. The results showed that the demand side response of electric, heating, and gas were considered in the regional comprehensive energy system with multiple energy storage devices, which not only made the load achieve the purpose of peak load cutting and valley filling, but also made the phenomenon of wind and sunlight cartailments be reduced. The energy utilization efficiency could effectively be improved by considering the electric, heating, and gas multi-load comprehensive demand response than the single consideration of the demand response. The environmentally friendly economic operation of the system was realized, the operation results verified the innovation of the theoretical technology.
