The unit commitment problem is a complex nonlinear optimization problem with large dimensions and linear and nonlinear constraints for which no approach has been yet able to extract the global optimum solution. In this paper, a new heuristic approach is represented which comprises two major stages: 1- Intelligent generation of initial population, 2- The bat search algorithm integrated with repair procedures. In this approach, the initial solutions are generated using a priority list and a new repair procedure for the violations related to minimum up/down time constraint. The solutions generated in this stage are infect initial solutions for the bat intelligent algorithm which performs a local search. To establish spinning reserve and minimum up/down time constraints, new procedures have been designed, which play important roles in the efficiency of the search and decreasing computational times. The proposed approach has been implemented on practical test systems of IEEE 54-unit, the Taiwan power system (Taipower), and the standard 100unit test system. The results reveal the approach’s success especially in achieving the lowest production cost in the literature for the first two systems.
