电-热-气综合能源系统多能流计算方法
Multi-Energy Flow Calculation Method for Integrated Energy System Containing Electricity, Heat and Gas
摘要
Abstract
In order to alleviate environmental pollution and improve utilization efficiency of end-used energy,integrated energy system (IES) becomes an important direction of energy structure adjustment in China.Under IES framework,traditional power flow calculation method,with power system as object,is difficult to meet requirements of analyzing coupled energy flow.This paper proposes an extended Newton-Raphson multi-energy flow calculation method,suitable for IES containing electricity,heat and gas.Firstly,models of electricity,heat and natural gas networks in IES are established.In view of complexity of traditional method to solve gas network including compressors,an improved practical method is put forward based on different control modes.On this basis,IES multi-energy flow model is built and Jacobi matrix reflecting multi-energy coupling relationship is derived considering grid-connected and island modes of power system in IES.Validity of the proposed method in multi-energy flow calculation and analysis of interacting characteristics is verified with numerical cases.关键词
