Scaling of wind energy conversion system for time-accelerated and size-scaled experiments

Abstract

This paper presents a scaling methodology based on dimensional analysis and applicable to systems’ mathematical models. The main goal of this research is to propose time-accelerated and size-scaled HIL (Hardware In the Loop) experiments, while keeping similarity with respect to the dynamics of the original system. The scaling process is presented using a simple wind turbine model. The scaling method is validated through simulations in which a wind turbine model and an electrochemical battery model are connected together. Finally, an experimental real-time validation is performed using physical emulators.
