PSO APPLICATION FOR DISTRIBUTED GENERATION ALLOCATION WITH THE OBJECTIVE OF REDUCING ACTIVE LOSSES
Distributed Generation (DG) presents several benefits for the electrical system, such as reduction of losses, increase in the voltage profile, besides improving the grid stability, postponing investments in reinforcements in the grid. DG also brings benefits to the environment when the energy source is considered clean, such as sun, wind, biomass, hydraulics, among others. In recent years several studies have been presented with the objective of allocating and dimensioning GD, using different objectives and techniques. This work seeks to investigate the application of the PSO algorithm (Particle Swarming Optimization) in the solution of the problem of optimal allocation of distributed generation, in its basic version and in a proposal that is under development. In this sense, it intends to introduce improvements in the original PSO algorithm through mathematical manipulations of the speed function and in the iterative process. Some preliminary tests were performed in a distribution system with 34 buses, which ensures the proper implementation of the original PSO.
