Unit Commitment Considering Operation of Energy Constrained Units

에너지제약을 갖는 발전기의 운전을 고려한 기동정지계획에 관한 연구

This paper presents a new method for solving unit commitment problem including hydro and pumped storage hydro units in a large scale power system. The proposed method makes it possible to get variable power of hydro and pumped storage hydro units and results in the better unit commitment with good convergency. Moreover this paper proposes an unit commitment algorithm to consider variable power of these units effectively by Lagrangian Relaxation method. By applying the proposed method to the test system, it is verified the usefulness of this method.
