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.
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.
For compensating reactive power, shunt capacitors are often installed in electrical distribution networks. Consequently, in such systems, power loss reduces, voltage profile improves and feeder capacity releases. However, finding optimal size and location of capacitors in distribution networks is a complex combinatorial optimisation problem.
