Research status and prospect of key problems of integrated energy system optimization model

Abstract

 In the traditional energy system, the operation structure of various energy sources is single, the coupling degree is not high, the efficiency of energy utilization is low, and the waste of clean energy appears, so the concept of comprehensive energy system arises at the historic moment.This paper firstly introduces the composition of the integrated energy system, summarizes the research status of the network power flow model of electric power, thermal power and natural gas, and summarizes the optimization operation method, leading to the integrated energy system source-source optimization model.The objective function, constraint condition, solution algorithm and operation cost of the optimization system are analyzed, and the key scientific problems and future research direction of the optimization management are put forward
