Comparative study between Interior Point and Particle Swarm methods for Optimal Renewable Distributed Generation location

This paper presents an optimal location of Renewable Distributed Generation (RDG) problem. For this, interior point method (IPM) and particle swarm optimization (PSO) have been used to locate three RDG plants in their optimal location. RDG represent 10.5% of the total load. First, two types of RDG are separately considered: those that inject only active power and ones that inject active power and consume reactive power on the grid. Secondly both types are considered together. The proposed methods are tested on 33 kV distribution busbars from the standard IEEE-30 bus system. Total generation cost has been chosen as the Fitness function allowing the power system to operate under technical and safety conditions. The results obtained are compared with these reported in the literature. They showed that the optimization of the DG position minimizes the cost of generation while reducing active power losses.
