This paper presents a hybrid method by combining cultural algorithm (CA) and particle swarm optimization (PSO) to solve the economic load dispatch (ELD) problem with valve-points effect. The proposed method is called SCAPSO. In SCAPSO, a new velocity update strategy is employed to replace the standard one in PSO, which can enlarge the search space and speed up the convergence. SCAPSO not only has the advantages of PSO, but also utilizes the CA to increase the diversity of the population so as to improve the global search ability. To verify the performance of the proposed method, the power system with 40 generating units is tested. Simulation results show the efficiency, convergence characteristic and robustness of proposed SCAPSO.
