Research on New Power System and the Modeling of CCHP System

With the introduction of the concepts of “carbon peak and carbon neutrality”, setting up a power system with renewable energy has become a top priority, so as to construct a new development pattern and comprehensively support the energy revolution. This paper carried on a detailed research on the new power system's architecture and one of its particular unit-CCHP. By reviewing literature and summarizing the current global energy structure and status, the definition of the new power system is provided. This paper draws a topology structure of new power system. Instead of modeling a complex and huge energy internet, this paper selects an important component of the energy internet-CCHP to do research on modeling. By setting up the model in PSCAD, the simulation results proves the validity of the proposed structure. The results will provide theoretical basis for next-step study on the new power system.
