摘要: This paper presents a new UPFC operation algorithm to find the operating point of UPFCs for system security level enhancement. The proposed iteratively minimizes index which indicates overload transmission lines. sensitivity representing change given set changes in real power outputs is derived. In each iteration, with this sensitivity, finds opening that reduces or increases margin. verified by IEEE 39 bus multiple UPFCs. study results show flow congestion can be relieved normally and margin guaranteed even an over loaded faulted condition applying
