This paper presents an efficient a hybrid rough set theory-PSO (RPSO) algorithm for solving large-scale economic load dispatch (ELD) problems in power networks with wind turbine. To realize the ELD, the valve-point loading effect, system load demand, power losses, ramp rate limits and prohibited operation zones are considered here. Simulations were performed on four different power systems with 3, 6, 15 and 40 generating units and the results are compared with two forms of power systems, one power system is with wind power generator and other power system is without wind power generator. The results of this study reveal that the proposed approach is able to find appreciable ELD solutions than those of previous algorithms.
