Abstract:

In this study, a novel heuristic algorithm is presented for solving Economic Load Dispatch (ELD) problems in power systems. The implemented method is a hybrid method, called Hybrid Immune Genetic Algorithm (HIGA). ELD problems are complicated and nonlinear in nature with equality and inequality constraints. Two benchmark ELD problems of different characteristics were used to investigate the effectiveness of the proposed algorithm. The proposed methodology easily takes care of valve-point effects, Prohibited Operation Zones (POZs), ramp-rate constraints and transmission losses. Comparing of the obtained numerical results with other available methods affirm the proficiency of proposed algorithm over other existing methods. It shows that the HIGA method has good convergence property. Furthermore, the generation costs of the HIGA approach are lower than other optimization algorithms reported in recent literature.
