Hydraulic coupling between hydropower plants,time of delay with downstream flow and possible factors such as wasting water,must take into account in the optimal scheduling of cascade hydropower plants containing hydro and thermal electric plants.

In order to improve the exploitation ability of small hydroelectricity and direct the routine work of Shaoguan local dispatching center,such as prediction and dispatching decision,a system which can support the optimization of dispatching decision has been established for the small hydropower station group of Shaoguan power grid.

In light of the results of the research a combined optimum dispatching system was set up for hydropower station group of.

For the requirement of the power system for the load, this article analyzes the key technique of daily scheduling for cascade hydropower stations.

Study of Optimal Operation ANN Model in Hydropower Stations;

For this reason, this paper puts forward a method based on the principles of system engineering and system-analysis, to conduct the long-term optimal operation of hydropower stations and reservoirs, in order to enhance a remarkable benefits and reliability of power generation of the group of hydropower stations.

This paper introduces the mathematical model of the optimal operation of small hydropower stations group by solving the generated energy in a hybrid method and provides the solving strategy for the optimal operation of small hydropower stations group by Genetic Algorithm(GA).
