Application of Shunt Capacitor Compensation Technique on Electrical Power Distribution System: A Review

Abstract

The performance and quality of service of the electrical power distribution system are one of the utmost issues bothering the power system operator. This matter is important in order to fulfil load demands, which increase significantly. The progress in enhancing the efficiency of the system is plagued by high real power losses and poor voltage profile especially in the conventional radial distribution system. Hence, researchers have adopted a variety of different approaches to solve these problems in electrical power distribution system. One of the techniques employed is installation of shunt capacitor (using Capacitor Switching Compensation). Studies have shown that when Capacitor Switching Compensation is incorporated into the distribution system, the system losses can be minimized by reducing the reactive power component. Capacitor Switching Compensation is a widely used technique in electric power distribution system to improve the power system performance. This study therefore, reviews some of the applications of Capacitor Switching Compensation in electrical distribution system based on voltage and reactive power control. Thus, the usage of Capacitor Switching Compensation help to control the reactive power on a distribution system, maintenance of the flat voltage profile, improve the system efficiency and the stability of the electrical power distribution system.
