THE OPF AND BUTTERFLY-PSO (BF-PSO) TECHNIQUE BASED OPTIMAL LOCATION AND SIZING OF DISTRIBUTED GENERATION IN MESH SYSTEM

This paper presents the combined optimal power flow (OPF) and Butterfly-particle swarm optimization (Butterfly-PSO or BF-PSO) techniques to determine the optimal location and sizing of distributed generation (DG). The multi-objective function based on the performance index consider for the multi- objective optimization. The 30-bus mesh system is used for the optimal planning of distributed generation.The comparative result analysis of the proposed methodology and the existing methodology is also reported in this work. The results show that the totalgenerating costand the nodal price are more economical. Also, the reduction in losses (active and reactive power loss) and the improvement in overall performance are efficient.
