Abstract

This paper constructs an integrated energy system framework that includes supply-side physical energy storage, demand response,and Vehicle-to-Grid （V2G） electric vehicles. The framework is designed to supply energy to communities composed of multiple types of buildings,with the objective of minimizing the total system operating cost. The operational parameters of the integrated energy system with generalized energy storage are been optimized accordingly. Furthermore,this study investigates the energy supply characteristics and operational features of the integrated energy system integrated with different types of generalized energy storage,and analyzes the energy coupling relationship between physical energy storage and demand response,as well as the correlation between operational outcomes. The results indicate that the total operational costs for typical winter and summer days are reduced by 23.96% and 55.90%,respectively,compared to an integrated energy system without energy storage. The integration of physical energy storage and demand response can lead to a reduction in the total system operating cost by approximately 18.69% and 52.36%,respectively. Demand response reduces the peak-valley difference rate of electricity load on typical winter days from 98.41% to 78.26%, and on typical summer days from 94.80% to 93.24%. This method tackles challenges in complex energy systems, such as diverse equipment types, complex control parameters, and difficult operational optimization. It also offers a theoretical foundation for optimizing complex integrated energy systems.
