This paper describes an algorithm for the flow rate optimization of hydropower plants. This algorithm has been implemented in the optimization system installed in Tombetta hydro power plant, in order to distribute the water flow rate between seven vertical Kaplan turbines maximizing the produced power. The new advanced flow control -"optimized"- has been added to the typical manual and automatic ones, by merging a mathematical approach (the optimization algorithm) and the physical response (plant delays, dynamics and hysteresis). This paper describes the process, its optimized control and the obtained results/benefits.
