ABSTRACT
Demand for electric power is increasing day by day due to the increase in commercial, residential and agriculture load and it is very important to decide which generating unit should be kept on and how much power should be dispatched from the committed generating units so that time varying load demand can be meet. In the proposed research, the recently developed hybrid meta-heuristics search algorithm, i.e. GWO-PS, has been applied to solve the unit commitment problem of the electric power system. The efficiency of the proposed hybrid algorithm has been tested for standard IEEE test system consisting of 4 and 10 generating units and it has been experimentally found that GWO-PS performs much better than GWO and PSO algorithms.
