Power Flow Calculation for Electric & Gas Integrated Energy System Considering Natural Gas Pipeline Leakage
摘要
Abstract
In view of the practical situation of natural gas pipeline leakage,an flow calculation of electric-gas integrated energy considering natural gas pipeline leakage is proposed.First,a model of natural gas network considering the pipeline leakage and the improved micro-gas turbine model is established.Then,the Newton-Raphson method is used to solve the flow of natural gas network,and the coupling relationship of gas turbines is used to solve the flow of power system iteratively.Finally,the power flow calculation results under states of the normal operation,the pipeline leakage and the pipeline failure of the coupling system are calculated and compared through a case study composed of the IEEE 30-node system and the Belgian 20-node natural gas system.关键词
