Optimal localization of voltage regulator banks in distribution systems based on technical and economic criteria

The optimal control of voltage profile with mono-phase voltage regulators banks in radial distribution feeders is presented. The formulation is made as a combinatorial optimization problem and solved by a Genetic Algorithm. The used optimization criteria are: voltage profile centred in the normal range, losses and costs reductions. The proposed method determine: the location and optimal adjustments of mono-phase regulator banks in maximum and minimum load conditions, and the maximum regulation.
