Research on Optimal Operation of Regional Integrated Energy System Considering Virtual Energy Storage Characteristics of Buildings

摘要

Taking into account the quasi-dynamic characteristics of the thermal system can improve the complementary characteristics of the integrated energy system and reduce the operating costs. Firstly, by analyzing the quasidynamic characteristics of the heating building and the human comfort model, the virtual energy storage model of buildings is established in this paper. Then, taking the lowest economic cost of regional integrated energy system as the objective function, an optimal model for integrated energy utilization is proposed under time-of-use (TOU) electricity price, and CPLX is adopted to solve the model. Finally, the simulation results show that the proposed method can improve the economy of regional integrated energy system.
