Utilizing capacitors has long been recognized to improve the voltage profile and reduce the losses in power system. Many strategies have been successfully developed to determine the best allocation of capacitors in order to achieve the greatest results. In this paper, a method to find the optimal placement and sizing of capacitors in distribution system is presented. The objective function is composed of the line loss and the voltage profile of each bus. A power loss sensitivity factor is employed to identify the appropriate buses for optimal location and sizing of capacitors which is formulated and determined by using Pattern Search Optimization. This technique is used in power distribution system to select candidate locations for compensating reactive power which will enhance the system voltage and lower the power loss. To validate the proposed method, the IEEE 34 radial distribution system is used to observe the method's performance, effectiveness, and efficiency in finding solutions. © 2022 Little Lion Scientific.
