Introduction and Efficiency Evaluation of Multi-storage Regional Integrated Energy System Considering Optimal Operation Integrated Demand Side Response

Abstract With the depletion of traditional energy sources, the Regional Integrated Energy System (RIES) came into being to solve the energy crisis and the problem of consumption. The battery, the thermal storage electric boiler and the P2G equipment are added into energy system. The impact of system operation was analyzed after adding different equipment. Then, the demand side response of the electric heating and gas are considered, and the economic operation model of the regional integrated energy system is established with the minimum operating cost of the system as the objective function. Seven scenarios were set up for comparative analysis. The results show that the demand side response of electric, heating, and gas are considered in the regional comprehensive energy system with multiple energy storage devices, which not only makes the load achieve the purpose of peak load cutting and valley filling, but also reduces the phenomenon of abandoned wind and sunlight and the system operation cost.
