摘　　要：研究了考虑高压直流输电(HVDC)和含典型灵活交流输电系统(FACTS)设备--晶闸管控制串联电容器(TCSC)的复杂电网结构异质性评估模型和算法实现问题。首先,基于电网负荷水平变化和电网结构重要度推导出电气介数指标,并在指标中综合考虑了电网运行状态对电网结构安全性产生的影响;其次,克服传统熵指标的不足,建立考虑HVDC和典型FACTS设备的电气介数扩展模型,并建立复杂电网异质性评估指标;最后,以IEEE30、IEEE39、IEEE118节点系统仿真验证了所提方法的合理性和有效性。A model and algorithm for heterogeneity assessment of complex power grid structures by considering HVDC and a typical flexible AC transmission system(FACTS)equipment are studied.Firstly,based on the load level change and the importance of power grid structure,this paper deduces the electrical betweenness index,and considers the influence of power grid operation status on the security of power grid structure synthetically.Secondly,to overcome the shortcomings of traditional entropy indicators,it establishes the expansion model of electrical betweenness by considering HVDC and typical FACTS equipment,and establishes the heterogeneity assessment index of complex power grid.Finally,this paper uses IEEE30 and IEEE39 and 118 node systems to verify the rationality and effectiveness of the proposed method with the simulation tests.
