Abstract
In the future, integrated functions and energy internet will become the direction of smart energy development. This puts forward requirements for power flow calculation and simulation of combined heat and power supply and unified modeling. Due to the complexity of the tespy heat network equipment model, the lack of node modeling corresponding to the power flow calculation model brings difficulties to the simulation modeling of the unified power and power flow calculation. Therefore, it is necessary to unify the interface of thermal network and power flow calculation model. Based on the tespy and pandapower libraries, this paper unifies the interface functions of heat network and power grid power flow calculation modeling, constructs a unified interface library Open-IES-Sim platform and builds a coupled power flow calculation process method and corresponding visualization results display program. The corresponding open source example is given. It is convenient for the future use of scientific research workers who need thermal and electrical coupling modeling and the demonstration research in education and teaching.
