Power Losses Reduced by using Particle Swarm Optimization (PSO)
Abstract: Due to the increasing price of electricity, it is very critical to accomplish an optimal decrease in active (real) losses throughout power transmission. The lowering of these failures is essential so because values of leakage losses in coastal lines are quite strong and result in significant transverse active losses. Load unbalancing is the biggest problem of the electricity network and SVC is stronger able to correct the malfunction of the …
