Abstract

This paper proposes an approach based on Bacterial Foraging Algorithm (BFA) for optimal placement of Distribution Generations (DGs). The optimal sitting and sizing of distributed generation is formulated as a multi-objective function including the network power losses minimization and voltage profile improvement. BFA algorithm has been employed to optimize the problem. To demonstrate the effectiveness of the proposed approach, it has been applied to 33 and 69 bus systems. The results of the proposed approach are compared with those of Genetic Algorithm (GA) and also Shuffled Frog Leaping Algorithm (SFLA) to reveal its strong performance.
