【 摘 要 】

The transition to competitive wholesale andretail markets for electric utilities around the world has been a difficult andcontroversial process. One of the difficulties that hindered the developmentand growth of the competitive wholesale power market is the absence ofefficient computational tools to assist the design, analysis and operation of acompetitive power market. PowerWorld simulator is an industry standard softwarepackage that has strong analytical and visualization functions suitable forextensive power flow study of a large power system. However, PowerWorld is notdesigned in such a way that can be used for the analysis and evaluation of acompetitive wholesale power market. This paper investigates mathematical modelsassociated with a competitive wholesale power market and how these models canbe converted and transformed in such a way that makes it possible to usePowerWorld for optimal power dispatch study of a competitive power market. Thepaper also develops a co-simulation mechanism to integrate PowerWorld andMatLab for a combined optimal power dispatch and unit commitment study.Finally, the paper demonstrates a case study for a large competitive electricpower system.
