摘要:
      针对典型的电—气耦合综合能源系统,提出一种基于统一潮流模型的静态灵敏度分析方法,用于分析电力与燃气供能系统间的交互作用机理。首先,给出电—气耦合综合能源系统的统一潮流模型。然后,在此基础上,定义电—气耦合综合能源系统的燃气压力—节点注入功率灵敏度矩阵。最后,结合典型场景下的综合能源系统灵敏度指标,分析电网节点注入功率对燃气压力的影响,定位综合能源系统的薄弱环节。算例表明,所提方法可为区域综合能源系统的安全稳定运行提供辅助信息,有效提升了系统的安全性。
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.
