Abstract
This work presents a multiobjective optimization approach to search the optimal position and size of many Wind based on Distributed Generation (WDG) in radial distribution network (DN). The goal are to minimize the active power losses (APL) and to maximize the voltage stability index (VSI). A multiobjective differential evolution with ranking-based mutation operator (MODE-RMO) algorithm is used to obtain the set of optimal Pareto solutions. The technique of fuzzy logic was used in order to chosen the best arrangement solution from the optimal Pareto. The approach is tested on IEEE network (69 bus) and validated on Algerian DN (59 bus).
