In this paper

the regional comprehensive energy system power flow analysis is carried out. Based on the characteristics of power network and natural gas network

the energy flow of the integrated energy system is modeled

and the energy hub model is constructed. Aiming at different operation

the problem of the integrated energy flow model is studied

and the unified solution of the multi-energy flow of the integrated energy system is realized. Based on the case study of a comprehensive energy system in a development zone

the operating status of the system under different operating modes is analyzed by constraints. The adjustment strategy is put forward without satisfying the constraints

verify the proposed power flow model and calculate the effectiveness of the algorithm.
