Development of a wind turbine model and simulation platform using an acausal approach: Multiphysics modeling, validation, and control

This article presents the development of Control-oriented, Reconfigurable, and Acausal Floating Turbine Simulator (CRAFTS). CRAFTS has a modular, hierarchical model architecture that enables rapid accurate simulation wind turbines. The facilitates incorporation variants, its system reconfiguration features help simulate multiple design variants. also supports integration models developed on causality-free platform (e.g., Modelica®) with existing causal models. focuses validation land-based turbine against OpenFAST, an industry-standard platform, for several test cases. Closed-loop scenarios are tested using standard ROSCO controller compared OpenFAST. In addition, nonlinear in our prior work is evaluated. cases demonstrate user-friendly computationally efficient capabilities to facilitate control co-design, assist incorporating multiphysics models, be adaptable allow simulations validate evaluate controllers.
