In accordance with the operational characters of the Channel--cascade hydropower sta- tions group, a multidimensional dynamic mathematical model with double--purpose is established for optimum dispatching of the cascade hydropower stations group. A large system decompose--coodinate method is used for soling this complex model success fully. Herein, the simulation model is used for inner operation of the stations, and the dynamic programmirg model is used for the whole system dis- patching.
