Comparative study between capacitor placement optimization (PSS/ Adept) and bus ranking method for optimal capacitor placement: article / Muhammad Fahmi Zainudin

This paper proposed efficient method for determining optimal capacitor placement in distribution network. The capacitor placement optimization was determined by the CAPO application available in the power system simulation programmed for planning, design and analysis of distribution system (PSS/Adept) and bus ranking method. Bus ranking determines suitable location by calculate loss reduction index. High loss reduction index is considered as critical area. CAPO is determined by application in PSS/Adept that already programmed inside that. Comparison between these methods has been made to determine more suitable method to optimal capacitor placement in term of low power losses and high power factor. This paper consists of finding the optimal location and size of capacitors in electrical distribution with an objective to improving the voltage profile, reduction power loss, and power factor correction. The proposed study was conducted on the 45 bus distribution system contain 33Kv bus and HKv bus. The result has shown that significant reduction in power losses, voltage profile and power factor improvement was obtained with the installation of capacitor bank at the suitable location with appropriate sizing. Proposed solution methodology has been implemented and the test results are including in this paper.
