Abstract

The use of capacitor banks in distribution system has many well-known benefits that include improvement of the system power factor, voltage profile, and reliability besides the reduction of losses due to the compensation of the reactive component of power flow. These benefits depend greatly on how capacitors are placed in the distribution system. Hence, to achieve the high reliable construction, switching capacitor has been placed to improve the main challenges of the network designing (reliability and reduce power loss) in the radial distribution system. As regards, the importance of the reliability and power losses are ignored in the distribution networks; the aim of this paper is primarily to establish an objective function for the parallel optimization of these parameters mentioned above. For this purpose, three reliability indices: System Average Interruption Frequency Index (SAIFI), the System Average Interruption Duration Index (SAIDI) and the Cost of Energy Not-Supplied (CENS) along with the power loss reduction parameter have been improved based on the proposed GSO algorithm. Then, the developed technique has been used on the IEEE standard distribution network as a problem-solving system and the best and worst placement of the capacitors banks are investigated.
