Optimal sizing and placement of shunt capacitors on the distribution system using Whale Optimization Algorithm

This paper aims at power loss minimization and reduction of cost due to losses in the distribution network as well improvement voltage stability profile via optimal shunt capacitor allocation. The allocation was obtained using Whale Optimization Algorithm considering technical (real VSI) economic objective functions sub-optimal may result undesired effects on network. sizes capacitors were placed location networks ascertain behavior before after their placements taking loss, losses, index performance metrics. A comparison these metrics under four cases, namely base case (case one), installation one SC two), two SCs three), three four) demonstrated standard IEEE 33-bus Dada 46-bus networks. results gave a percentage 33.74% with 27.60% annual net saving for 22.24% 25.60% Hence, total costs. Also, significantly improved.
