Einsatzmöglichkeiten einer übergeord-neten Steuerung beim automatisierten Betrieb von Staustufenketten

While automated local controllers for water resources management are a widely used assistance system for the operators of hydropower plants, superordinate regulation modules are rarely found. Nevertheless, a variety of objectives in cascades of hydropower plants can only be achieved with coordinate operation. Some of these objectives are the smoothing of the discharge or the generation of more complex and higher remunerated power products, such as control reserve power. The paper shows a solution for smoothing the discharge of the upper Inn by storing and releasing volume in two subsequent reservoirs, which is determined by specific algorithms using a discharge forecast from upstream gauges. It also compares different strategies of hydropeaking with respect to the generation of control reserve power and describes two projects for the coupling of the simulation tools with control room interfaces in order to make them usable as a training simulator for the staff.
