Optimal Placement of Distributed Generator using BFPSO

Distributed generators (DGs) are a dependable alternative for providing customers with affordable and reliable power. It is described as an electric power source connected to the distribution network or the customer's premises. To get economic, technological, environmental, and regulatory benefits, it is required to plan DGs optimally in terms of size, placement, and type. In this paper, optimal sizing and placement problem of DGs has been addressed. A multi-objective formulation considering loss reduction in conjunction with improvement in voltage profile has been formulated. The analysis has also been conducted through variation in weighting factors. An enhanced version of conventional particle swarm optimization (PSO) called as Butterfly-PSO (BF-PSO) has been used for DG sizing and placement. The study has been carried out for the IEEE 33 bus radial distribution feeder. The results obtained through BF-PSO has been compared with PSO in order to establish its superiority.
