Optimum Deployment of Distributed Generation with Shunt Capacitor to maximize the Economy of Distribution System

In this study, to keep the secure and stable operation of the power system, distributed generation (DIG) and shunt capacitor are optimally placed in a radial distribution system. Many researchers are working on optimal DIG and shunt capacitor placement using intelligent method like genetic algorithm, artificial neural network, fuzzy logic and ant colony algorithm. In such regard, a particle swarm optimization (PSO) based technique is used to determine the optimal location and optimal size of the DIG and shunt capacitor. The main purpose of this study is to increase the economic advantage of the distribution system operator as well as to decrease the active and reactive power loss. Different indexes such as Cost Index (CI), Active loss reduction index (ALRI), and Reactive loss reduction index (RLRI) are proposed and formulated accordingly. Different cases are considered and the obtained results are deeply analyzed for finding out the best option of system operator.
