Abstract

Compensation for reactive power is provided, and the use of capacitor banks reduces both active and reactive power losses in distribution systems. In the power system, the capacitor also helps control the voltage and power factor. The genetic algorithm (GA) to the stage finds appropriate OPC. The voltage profiles of the system have improved as a result. The number of capacitors at minimum load has been determined for the candidate buses for optimal capacitor bank placements. To assess the sensitivity of compensating power losses, the calculation of optimal capacitor placement is done at peak load. By using this method, the sag and swelling of the voltage caused by the lead phase of the system are prevented in the increase or decrease of the load within the IEEE standard. Using a ETAP 16.0, a load current analysis of 33-IEEE Simply Radial Test System was made to portray the effect of the method. The Newton-Raphson iteration technique was used for both the original system and the improved system.

Keywords: Radial distribution system (RDS), ETAP, Optimum capacitor placement (OCP), Genetic Algorithm (GA).
