Abstract—The research paper introduces a water cycle algorithm (WCA) for optimizing the placement and sizing of Distributed Generation (DGs) and capacitors banks (CBs) in distribution systems. The objective is to minimize power losses, voltage deviation, and total electrical energy cost, and improve voltage stability. The proposed method emulates the water flow cycle, considering streams, rivers, and the sea. The study evaluates the performance of the approach using five operational cases in three distribution systems: IEEE 33-Bus, 69-Bus, and Sankhu feeder network. Results demonstrate significant reductions in power loss and improvements in voltage profiles. For IEEE 33-Bus and 69-Bus, power loss decreased by up to 92.04%, and minimum bus voltage improved by up to 0.990pu. For the Sankhu feeder network, power loss was reduced by up to 98.63%, and minimum bus voltage improved by up to 0.993pu. The proposed Water Cycle Algorithm proves its effectiveness in optimizing DG and CB placement and sizing, outperforming other optimization algorithms.
