Abstract

In this paper, a model-reference control scheme for wind turbine systems in the Takagi-Sugeno framework is proposed. This work deals with the model reference control approach to provide wind turbines’ fast frequency response (FFR) in fluctuating wind conditions. The proposed scheme is applied to a generic wind turbine model for the partial and full-load region. The controller coefficients are calculated using a set of proposed Linear Matrix Inequality (LMI) conditions. The design process is described in detail, including a controller performance in the wind turbine’s partial and full load region.

Zusammenfassung

In dieser Arbeit wird ein Modellreferenz-Regelungskonzept für Windturbinensysteme im Rahmen des Takagi-Sugeno-Ansatzes vorgestellt. Ziel ist es, durch modellreferente Regelung eine schnelle Frequenzantwort (Fast Frequency Response, FFR) der Windturbinen unter variablen Windbedingungen sicherzustellen. Das Konzept wird auf ein generisches Windturbinenmodell angewendet und sowohl im Teillast- als auch im Volllastbetrieb untersucht. Die Reglerparameter werden auf Basis vorgeschlagener Linear-Matrix-Ungleichungs-Bedingungen (LMI) bestimmt. Der Entwurfsprozess sowie die erzielten Regelungsergebnisse in den unterschiedlichen Betriebsbereichen werden ausführlich beschrieben.
