摘要
应用模糊集理论,在计及发电机出力及负荷不确定性的基础上,研究了线路退运后的模糊切负荷量计算方法。发电机出力、发电机可用度及负荷的不确定性用梯形模糊数描述,推导了线路退运的模糊潮流计算过程,并结合基于灵敏度控制的过负荷控制方法提出了线路退运后的切负荷量计算方法。通过在IEEE118节点系统中进行切负荷量计算,证实了在进行线路退运后切负荷量求解中计及不确定性的必要性和文中方法的应用价值。
By using fuzzy sets theory and on the basis of considering generator output and load uncertainties,this paper stud-ies calculation method for fuzzy load shedding capacity after line outage.It uses trapezoidal fuzzy numbers to describe gener-ator output,generator availability and load uncertainties and deduces fuzzy flow calculation process of line outage.Combi-ning overload control method based on sensitivity control,it proposes calculation method for load shedding capacity after line outage.By applying in IEEE 1 1 8 node system,it proves necessity to considering uncertainties in solving load shedding capacity after line outage and application value of the above method.
