Minimization of Power Loss in Distribution System by Tap Changing Transformer using PSO Algorithm

Energy is a primary requirement for everyone and it is available in different forms in nature, in all forms of energy “Electrical Energy” is the most significant and useful in the daily life of humans. In the last two decades, the usages of electrical & electronic devices are rapidly increased and technology modernizes lifestyles as well as simplified their lives. In this way, the load demand also significantly increased and leads to an imbalance between generated power and load demand. Load uncertainty also increased with the rise of load demand; it leads higher power losses & poor voltage in distribution system (DS). The main objective of this paper is going to discuss the minimization of losses by adjusting tap settings of the distribution transformer with the help of particle swarm optimization (PSO) algorithm. The proposed approach verified on 15 bus distribution system using MATLAB. Electric vehicle charging stations are located in the distribution system to represent the load uncertainty.
