Algoritmo PSO com Voos de Lévy para Alocação e Dimensionamento de Geração Distribuída

Distributed generation (DG) offers several benefits to the electrical system, such as the reduction of losses and improvement of the voltage profile. DG benefits can be maximized when allocation and sizing are optimal — a problem known as the Optimal Sizing and Placement of Distributed Generation (OSPDG). This paper presents a new meta-heuristic that associates PSO (Particle Swarm Optimization) with L´evy flights (LF) to solve the OSPDG, identified in this work as LFPSO. The tests carried out on the 69-bus distribution system indicate that the LFPSO is superior to the PSO in relation to the convergence process. The results obtained considering the allocation of up to three DG point to a reduction of 98.1 % in active power losses.
