【 摘 要 】

Integrated energy system (IES) has become the trend of energy development in the future, but the degree of coupling between energy systems in traditional systems is not high, and the power flow calculation method based on power system will be difficult to meet the need for coupled energy flow analysis. This paper firstly uses the coupling matrix of the energy hub to construct a coupled model of the integrated energy system that fully considers the coupling of the power network and the natural gas network; then we use the Newton-Raphson method to calculate the power flow; finally, an example is used to verify that the comprehensive coupled model will have practical significance in the construction and operation of the integrated energy system.
