Optimal Power Generation, Power Factor and Location of Multi Dispersed Generation Using Chaotic PSO

Abstract

The optimal location and sizing of dispersed generations (DGs) play a crucial role in improving the performance of the distribution network. The objectives of incorporating DG into the distribution system are effectively achieved when the DG's are optimally placed and their MVA rating is optimised while satisfying voltage, current and power constraints of the system. In most of the past work in the field, optimal active power generation from the DG along with optimal location was concentrated upon. In this paper, both active and reactive power generation from the DGs is optimised along with optimising the location of the DGs. Here the optimisation is done using a chaotic particle swarm optimisation (CPSO) method which is found to give better results when compared to the general PSO. The effect of DGs on short circuit analysis of the grid-connected system is also analysed here. The algorithm is implemented on 33-bus and 69-bus radial networks.
