Advanced control of a hydroelectric power plant

The paper presents an original method for controlling the real power delivered by a hydroelectric power plant to local electrical grid. The advanced control is based on: the implementation of the Internal Model Control strategy in order to obtain the system stabilization and robustness; the implementation of two feed-forward loops in order to reject more efficiently the effect of the disturbances; a control loop for the frequency correction. The main controller from the proposed control system has an original architecture and it is tuned using an original concept, too.
