【Abstract】 The purpose about power system optimal dispatch was stated and the development of power system optimization in recent twenty years was reviewed from two aspects,classic economic dispatch and optimal power flow in this paper.Some problems about each dispatch method during development were analyzed and countermeasures for these problems were provided.Because of its fast computation speed,classic economic dispatch was often used for on line dispatch.Compared to classic economic dispatch,the result of optimal power flow was very precise but computation procession is slow.So this method can’t be used in real time.Some urgent problems in the two methods were put forward at the same time.更多还原
