Allocation of distributed generation to minimize losses in the distribution power system

Abstract

Distributed generation (DG) has been increasing the electricity generation capacity around the world, becoming an area of great interest. DG benefits the distribution system by reducing losses and improving the energy quality and reliability of the system, in addition to the greenhouse gases reduction. The problem of dimensioning and allocating DGs is important since their installation in nonoptimal places can result in increased system losses and operation costs. This article presents a method for optimal allocation and dimensioning of DGs to reduce total losses in the power distribution feeders. The solution technique uses the greedy randomized adaptive search procedure together (GRASP) with tabu search. Results under a real-world distribution system shows the efficiency of the proposed methodology.
