A fast technique for unit commitment problem by extended priority list

This paper introduces. a new unit commitment problem, adapting extended priority fist (EPL) method. The EPL method consists of two steps, in the first step we get rapidly. some initial unit commitment problem schedules by priority list (PL) method. At this step, operational constraints are disregarded. In the second step unit schedule is modified using the problem specific heuristics to fulfill operational constraints. To calculate efficiently, however, note that some heuristics applied only to solutions can expect improvement. Several numerical exam pies demonstrate the effectiveness of proposed method.
