Determination method of hydropower station water storing and releasing dispatch and operation scheme based on energy storage analysis

The invention discloses a determination method of a hydropower station water storing and releasing dispatch and operation scheme based on energy storage analysis. By the method, performance indexes such as incoming flow energy losses, used (future) reservoir stored energy, practical electric energy capable of being generated and stored energy utilization efficiency can be calculated and analyzed) according to different utilization conditions of incoming flow energy and reservoir stored energy in the process of water storing and releasing and based on different operation schemes specific to falling of a water level in a dry season and ascending of the water level in a storage period, the demand for electric quantity of a system is combined, and optimal water storing and releasing operation manners of various time periods are obtained. The method has the advantages that the achievement of hydropower station water storing and releasing operation manners where water quantity and a water head are coordinately utilized is studied by utilizing the point of view of high-efficiency utilization of the stored energy, and more practical and credible instructions can be provided for scientifically formulating dispatch decisions for the hydropower station which is operated in a power grid.
