Restructuring of power system stresses the need for economic and reliable generation of power. Therefore generating units should be committed considering fuel cost and reliability level of the system. This necessitates the need for multi-objectives to be met in a unit commitment problem (UCP). Since the above objectives are conflicting in nature, a novel methodology employing optimal deviation based...
This paper presents a new approach for binary and real coded particle swarm optimization (BRPSO) algorithm to solve the unit commitment problem (UCP). On solving UCP, the proposed binary coded PSO finds the ON/OFF status of the generating units while the economic dispatch problem (EDP) is solved using the real coded PSO. Tanh function is proposed to improve the particle searching mechanism in binary...
This paper proposes a new method for the incorporation of the generation unit and transmission line unavailability in the solution of the unit commitment problem. The above parameters are taken into account in order to assess the required spinning reserve capacity at each hour of the dispatch period, so as to maintain an acceptable reliability level. The unit commitment problem is solved by a Genetic...
