Therefore, the problem addressed in this paper is the ucp which is the scheduling of generators to Ø the life style of a modern man follows regular habits and hence the present society also follows regularly repeated cycles or pattern in daily life. Unit commitment (uc) is a popular problem in electric power system that aims at minimizing the total cost of power generation in a specific period, by defining an adequate scheduling of the.

A classical problem in scheduling and integer programming is the unit commitment problem.in this problem, our task is to turn on and off power generating plants, in order to meet a forecasted future. The greatest advantage of applying the lagrange relaxation method for the unit commitment problem is that it can relax (ignore) each generator's output dependency caused by the demand.
