To keep the current pace, at which the European energy transition is progressing to date, decentralized energy production units are required in the future, which can be operated more flexibly than at the current state. While the control of a variable-speed wind turbine is still primarily aimed at maximizing the annual energy production, the provision of ancillary grid services and the explicit regulation of structural loads will become increasingly important for maintaining levelized costs of energy at an acceptable level.

Model-predictive control represents an attractive and effective means for harmonizing these competing operating targets, on the one hand because of the quickly increasing computing power of industrial control hardware and on the other hand, because of the availability of new, forward-looking sensor devices for the wind speed.

This presentation starts with the introduction of the generic control problem to be solved for individual wind energy plants. Based on this, suitable formulations for economic model-predictive control of a wind energy plants are presented. Based on industrially-relevant simulation scenarios, the improvements that can be achieved with MPC are compared with the conventional control concept of a turbine. The presentation concludes with a discussion of the remaining challenges to be overcome for the industrial applicability of the MPC technology.
