Customer ServiceSeries capacitor compensation has been applied for transmission systems to increase the system capacity and enhance its voltage profile. In distribution systems, the main advantage of the series compensation is its voltage boost to the buses downstream from where the capacitor is positioned.
In the method, the high-potential buses are identified using the sequential power loss index, and the PSO algorithm is used to find the optimal size and location of capacitors, and the authors in have developed enhanced particle swarm optimization (EPSO) for the optimal placement of capacitors to reduce loss in the distribution system.
Research results The placement of capacitors resulted in improved voltage levels across the distribution network. Voltage deviations from the nominal value were significantly reduced. There was a notable reduction in active power losses (I2R losses) throughout the distribution lines.
Distribution systems commonly face issues such as high power losses and poor voltage profiles, primarily due to low power factors resulting in increased current and additional active power losses. This article focuses on assessing the static effects of capacitor bank integration in distribution systems.
The importance of the research lies in the importance of its topic, as Proper capacitor placement helps maintain the voltage levels within desired limits throughout the distribution network, ensuring stable and reliable power supply, and minimizes voltage drops across the distribution lines, improving the overall voltage stability of the system.
The results show that the approach works better in minimizing the operating costs and enhancing the voltage profile by lowering the power loss. Hybrid optimization of particle swarm (PSO) and sequential power loss index (SPLI) has been used to optimal capacitor allocation in radial distribution networks for annual cost reduction .
