ABSTRACT

This work illustrates the best possible placement of multiple Distribution Generators (DGs) in the distributed system. The main aim of the chapter is to reduce the power losses in the distribution side. This can be achieved by DGs that should be operated at power factors nearer to the power factor of combined load in the considered system. Moreover, the voltage stability index (VSI) in the distribution network has been improved by placing multiple DGs. In this work, the ability of the DG to withstand the load growth for years is also discussed. This chapter suggests SFLA (Shuffled Frog Leaping Algorithm) for optimal placement of multiple DGs. This proposed methodology is tested on IEEE radial distribution system having 33 buses. The base case analysis is done along with single, double, and triple DG(s) placement. The results were compared with few optimizations methods such as improved analytical approach, mixed integer nonlinear programming, and particle swarm optimization. The comparison encourages the use of SFLA for DG placement. The load growth analysis helps us to keep track of future expansion planning requirement.
