Capacitor Placement Using Ant Colony Optimization and Gradient

This paper aims to minimize the total active losses in electrical distribution systems by means of optimal capac- itor bank placement. The proposed methodology to solve this optimization problem is the Ant Colony Optimization (ACO) metaheuristic. The gradient method is combined with the meta- heuristic in order to accelerate the convergence of the ACO algorithm. The methodology has been applied successfully in three real systems.
