摘要:In this paper allocating of DGs and optimal number, locations and size of solid State FaultCurrent Limiters (SSFCLs) is performed for a case study contains modern protective devices.Genetic algorithm (GA) is employed for optimal allocating of DGs and SSFCLs. Thedistribution system contains remote controllable switches in addition to conventional tools suchas fuses, relays and circuit breakers. The results demonstrate that minimization of distributionprotection system cost, is still valid for a distribution system, which contains modern protectivedevices.
