Abstract :In this paper, an effective methodology is proposed for the optimal allocation of conventional insert ignore into journalissuearticles values(Gas turbines); and renewable based distributed generators insert ignore into journalissuearticles values(solar, wind); in the distribution system insert ignore into journalissuearticles values(DS); are presented. The objectives are to minimize real, reactive power losses and emission produced by the sources. Initially, the best locations for placement of  DGs  are identified by voltage stability factor insert ignore into journalissuearticles values(VSF); concept. The number and size of solar, wind based DGs and gas turbines corresponding to these locations are determined by applying search based dragonfly algorithm insert ignore into journalissuearticles values(DFA);. The generation uncertainties associated with wind and solar based DGs is effectively modeled by Weibull and beta probability distribution functions insert ignore into journalissuearticles values(PDF); to determine the exact output power. Two different scenarios, i.e. optimal allocation and the combination of different types DERs in the distribution system is considered in this analysis. The developed method is tested on IEEE 33 and 69 bus distribution systems. Finally, the obtained results are compared with other promising methods in the literature. The results show its effectiveness in terms of solving respective objective function.
