A key topic of the European CL‐Windcon project, and specifically WP1 of the project, is the accurate modelling of wind turbine and wind farm dynamics at a varying range of fidelities. Hence, this document describes the different numerical models employed throughout the project and presents their arrangement and fidelity classification based on the different capabilities, limitations and complexity of their underlying physics. The description of the four categories selected: steady‐state models, control‐oriented dynamical models, medium‐fidelity simulation models, and high‐fidelity simulation models is included and discussed in the document.
