In order to overcome the problem of large energy consumption cost in the traditional energy efficiency modeling method of integrated energy system, the energy efficiency modeling method of integrated energy system in coastal area is proposed to reduce the energy consumption cost of integrated energy system in coastal area. Based on the energy network of the integrated energy system, the energy conversion relationship of the integrated energy system is analyzed, and a group of independent variables in the energy network is selected to calculate the complexity of the energy network. The time-varying energy network equation of the comprehensive energy system is established by establishing the difference matrix of the strength at both ends of the branch. Combined with the process of energy efficiency modeling of integrated energy system in coastal areas, the cost of energy efficiency modeling of integrated energy system is improved, and the energy efficiency modeling of integrated energy system is realized. The simulation results show that the proposed energy efficiency modeling method has lower energy consumption cost in the process of energy efficiency modeling.
