Particle Swarm Optimization Based Approach for Loss Reduction in Unbalanced Radial Distribution System
نویسنده
چکیده
The losses at distribution level contribute a major portion of power system losses. Proper sizes of shunt capacitors in unbalanced radial distribution systems (URDS) can reduce some portion of this loss and can improve the voltage profile of the feeder section. Most conventional optimization techniques are in capable to solve this hard combinatorial problem with set of operating conditions where as particle swarm optimization (PSO) algorithm is very suitable. This paper presents an efficient algorithm for determining the location, type and size of capacitor bank to be installed in unbalanced radial distribution system. The main objective function formulated consists of two terms: Cost of energy loss and cost related to capacitor purchase and capacitor installation, so that the fitness function is to be maximizing for the net saving.
