Abstract 

This paper presents a new approach for capacitor placement in the modified IEEE 16 bus distribution system that determines the optimal locations and size of capacitor with an objective of improving the voltage profile and reduction of power loss. The location of the buses where the capacitors should be placed is decided by a set of rules given by the Fuzzy Expert System (FES) and the sizing of the capacitors determined by Q-V analysis in these buses. A comparison is made between the proposed Fuzzy approach and the Particle Swarm Optimization (PSO) algorithm in terms of improve voltages with reduce losses and economic savings achieved to study the performance of both Techniques. The proposed Fuzzy Technique is proven to give better results. 

Keywords:  Distribution Systems, Capacitive compensation, Loss minimization, Fuzzy.
