Abstract

Renewable energy sources are gaining more and more interest because they are sustainable and nonpolluting. Although renewable energy is useful, it can cause voltage violation due to its uncertainty in power output. In this paper, a solution method has been proposed to coordinate dispatchable Distributed Generation (DG) with voltage control devices for optimally regulating voltage profile by using Particle Swarm Optimization (PSO). In addition, Monte Carlo Simulation is applied to calculate probabilistic load flow from the uncertainty of renewable energy DG and loads. The proposed method is simulated in IEEE 34-bus distribution test system, and the satisfactory results are obtained.
