Optimal placement and sizing of distributed generation units using different cat swarm optimization algorithms

Abstract

This paper presents a proposed method to allocate the distributed generation (DG) units on distribution networks using cat swarm optimization algorithm. The proposed method finds the optimal placement and sizing of DG units. The objectives of the optimization problem are minimizing: total generation costs, total power losses, total emissions produced by the generation units and improving the voltage stability. The proposed method depends on cat swarm optimization (CSO) algorithm and parallel cat swarm optimization (PCSO) algorithm. The proposed optimization methods are tested on the IEEE 33-bus and IEEE 69-bus distribution systems. The results of these algorithms are compared to other previous methods that are reported in this field. The proposed optimization methods are considered effective and perfective method to find the placement and the sizing of the DG units on distribution systems.
