Power losses minimization is an important area in power system that needed to be maintained at lowest possible values. The optimal placement of Distributed Generation is able to strengthen and improve the power system efficiency hence reducing the power losses. The increasing in the number of electrical consumers causes the increase in power losses in the system. Hence, the DG is used to reduce the power losses in the distribution system but DG must be placed at their optimal location in the system to avoid any negative effect such as increasing in power losses. The purpose of this project is to optimize the optimal location of the Distributed Generation in a distribution system. The optimal location of Distributed Generation in a distribution system usually done to reduce the power losses and improving the voltage profile of the system. Next, this project focuses on two type of bus system which are IEEE-9 and IEEE-33 bus systems. The power losses will be analyze using Newton-Raphson using MATLAB software. The method used to optimize the location of the DG in this project is Particle Swarm Optimization (PSO) which to obtain the minimum possible power losses. Fixed size of DG is used for both system and one unit DG is used for IEEE-33 bus and 2 units DG is used for IEEE-9 bus system. The result of simulation of PSO is shown in the Section 6 below.
