Dynamic Power Flow Calculation And Open Simulation Of Electro-Thermal Coupled System

This paper relates to the system analysis of energy internet with multi-type energy coupling complementation characteristic, the quasi-steady model of thermal system was built, and the dynamic power flow calculation method of electro-thermal coupling energy system was studied. Based on Power System Analysis Software Package (PSASP), the dynamic power flow calculation program was developed. Besides, open simulation was studied and the interface was developed accordingly, user-defined models could be inserted to the simulation of multi-type energy coupling system. In this paper, mature power system analysis software functions are fully used, and dynamic calculation of integrated energy network is realized, at the time, the scope of the program is extended to adapt to the situation of new equipment, components and new control strategies emerging nowadays.
