基于统一潮流模型的电-气耦合综合能源系统静态灵敏度分析
Static Sensitivity Analysis of Integrated Electricity and Gas System Based on Unified Power Flow Model
摘要
Abstract
Aiming at the typical integrated electricity and gas system(IEGS),the static sensitivity analysis method based on the unified power flow model is used to analyze the interaction mechanism between the electric power and gas supply system in the system.Firstly,the unified power flow model of the IEGS is given.On this basis,the gas pressure-node injection power sensitivity matrix of the IEGS is defined.Finally,combined with the regional comprehensive energy system sensitivity index, the impact of node injection power of power grid on gas pressure is analyzed,and the weak links of regional integrated energy system are located.The results show that the proposed method can provide auxiliary information for the safe and stable operation of regional integrated energy system,and effectively enhance the security of the system.关键词
