Abstract: An important criterion in power system operation is to meet the power demand at minimum fuel cost using an optimal mix of different power plants. Moreover, in order to supply electric power to customers in a secured and economic manner, unit commitment (UC) is considered to be one of the best available options. The problem of unit commitment (UC) is to decide which units to inter connect over the next T hours, where T is commonly daily or weekly duration of time. The problem is complicated by the presence of constraints and also it is complicated because it involves integer decision variables, i.e., a unit is either committed or not. In this paper SFLA algorithm is used for the solution of UC by meeting all its constraints. Minimum up and minimum down constrains are directly coded. This SFLA algorithm has been applied to 10 generating units considered for one day scheduling period
Keywords: Economic dispatch, generation scheduling, optimization techniques, unit commitment.
