Economic Analysis of Optimal Planning of Distribution System in Presence of DGs with Considering Power Quality Indices with Fuzzy Logic Algorithm (FLA)

One of the remarkable phenomena in power systems is the appearance of Distributed Generation (DGs). DGs can improve losses and voltage profile of system. In this paper Fuzzy Logic Algorithm is used to obtain optimal number, capacity and location of DGs for radial distribution networks. First of all FLA is used for optimal placement and capacity of DGs in the network. A composition of power quality index such as voltage profile improvement with economic indices is defined as the objective function in the optimization procedure. This method was carried out on a 33- feeder distribution network. Simulation results validate the effectiveness of the proposed method.
