Placement and Sizing of Distributed Generation in Distribution System

Advances in power systems motivated by the increasing demand of generation sources connected to the power distribution system have brought several benefits, such as losses reduction and improved voltage profile. However, further research must be conducted to avoid the disadvantages and to improve the benefits. This paper applies differential evolution meta-heuristic to perform sizing and placement of Distributed Generation units in radial distribution networks in order to reduce active power losses. Besides, the proposed algorithm allows an evaluation of the active power losses behavior when compared to the number of generating units placed and dimensioned by the algorithm. Simulations have been performed using the IEEE 33-bus and IEEE 69-bus for evaluating the proposed methodology. The results obtained demonstrate the ability of the algorithm for placing and sizing Distributed Generation units in addition to evaluate the optimal number of generating units to minimize the active power losses in the networks.
