Research on Multi-energy Power Flow Calculation of Thermoelectric Coupling Integrated Energy System

Integrated energy system (IES) is an important technology for energy efficiency improving, energy conservation and emission reduction. The electrothermal coupling system with combined heat and power (CHP) as the core is one of the widely used IES at present. The power flow calculation of the electrothermal coupling system can provide the necessary data for the safe and stable operation of the IES and improve economic benefits. In this paper, the basic structure of the electrothermal coupling system is analyzed, and the joint solving process of multi-energy flow is proposed and verified by the simulation example.
