TGC eco-friendly generation multi-objective optimal dispatch model and its solution algorithm

The optimal ecological flow of Yichang station is determined as ecological benefit evaluation standard based on monthly frequency computation method and ecology elements of the Yangtze River. An eco-friendly generation multi-objective optimal dispatch model of cascade reservoir is proposed according to the major ecology problems and the specific engineering practice in the Three Gorges Cascade ( TGC ) . A dual-subpopulation multi-objective differential evolution algorithm with external archive , elitist selection and chaotic migration is presented to solve the optimal dispatch model. The results reveales that a lot of non-dominated and uniformly dispatch schemes for decision-making can be generated in short time.
