PREVENTIVE AND CORRECTIVE SWITCHING FOR FEEDER CONTINGENCIES IN DISTRIBUTION-SYSTEMS WITH FUZZY SET ALGORITHM

This paper presents a new fuzzy-set based algorithm for optimal switch ing. The algorithm deals with feeder contingencies and service restora tion. Optimality will be pursued to get a preventive solution to avoid further contingencies. Issues of the inter-feeder load balance and in ter-phase load balance will be emphasized. A fast algorithm has been d eveloped by the fuzzy approach to avoid numerical computation. And the state-space of all the feasible solutions is confined by limited sear ch instead of the time-consuming exhaustive search.
