A mathematic model with its optimal scheduling objective of achieving maximum power output does not meet the environmental and ecological demands.The paper gives a thorough research on various optimal scheduling mathematic models for small hydro plant.An optimal scheduling mathematic model with controlled reservoir level and minimum surplus as its objectives is proposed.The environmental and ecological functions of small hydro are taken into consideration in this model.It studies the optimal scheduling of small hydro plant based on Cultural Algorithm(CA),which characterized by co-evolution and co-promotion of the population space and belief space.An improved GA is used to represent the population space and a APSO algorithm to deal with the local variation as belief space governing population space.The optimal scheduling results delivered by different mathematic models are analyzed by utilizing CA.It is showed that the CA and the developed model are effective.
