This study deals with the application of hybrid PSO and GSA (hybrid PSOGSA) algorithm to solve the CEED problem. The PSOGSA algorithm profits from the abilities of both PSO and GSA algorithms. The performance of the proposed algorithm is tested on three standard test systems, with different constraints and various cost curve natures. Numerical results obtained by the proposed approach were compared with other optimization results reported in the literature recently.
