A New Method of Capacitor Allocation and Sizing in Distribution Network Using Combined Fuzzy - Qv Analysis

Abstract

This paper presents a new approach for capacitor allocation and sizing in the modified IEEE 16 bus distribution system connected with wind machine with an objective of improving the voltage profile and reduction of power loss. Three cases are made with change the position of wind machine along three feeders in the proposed network, the case that gives better result for average bus voltage and total power losses selected for further simulation. The location of the buses where the capacitors should be placed is decided by a set of rules given by the Fuzzy Set Theory FST and the sizing of the capacitors determined by Q-V analysis in these buses. In addition calculated wind power factor WPF which achieve the reactive power required from wind farm in point of network connection POC. A comparison is made between the proposed Fuzzy approach and the Particle Swarm Optimization PSO algorithm in terms of improves voltages with reduces losses achieved to study the performance of both Techniques.
