Optimal Placement Distributed Generation by Genetic Algorithm

Distributed Generation (DG) is a promising technology to many power system problems such as voltage regulation, power loss, etc. Genetic Algorithm optimizes the placement Distributed Generators in radial distribution systems to minimize the total power loss and also to improve the voltage sag performance. DGs may be placed at any load buses. This paper proposes Genetic Algorithms (GA) for solving optimal multi-distributed generation (DG) location and capacity. The objective is to minimize the real power loss within security and operational constraints. The analytical expression and the methodology are based on the exact loss formula. The effect of size and location of DG with respect to loss in the network is also examined in detail. A detailed performance analysis is carried out on 33 bus system to demonstrate the effectiveness of the proposed methodology
