This chapter presents the applications of hybrid PSOGSA algorithm and hybrid GSA-SQP algorithm to the ORPD problem. Performances of the algorithms for the ORPD problem are studied and evaluated on standard IEEE 30-bus and IEEE-118 test systems. The simulation results are compared with those of other metaheuristic optimization algorithms reported in the literature recently. In addition, a critical analysis of the ORPD results is also presented.
