In the meantime of considering the goals like maximum of generation benefit of cascaded hydropower plants 袁 generation cost minimum of thermal power units and minimum water consumption for power generation of cascaded hydropower plant 袁 the paper takes optimization goal of minimum carbon dioxide emission into account. Aiming at the difficulty in weighting of objective function in short鄄term optimized operation and dispatching 袁 the paper proposes an approach based on overall coordination satisfaction of objective function 袁 which improves algorithm performance via adoption of natural selec
