The dynamic behaviour of wind turbines continues to be a major area of research in the wind power industry. Increasingly, wind turbines are grouped into large arrays that form farms capable of generating hundreds of megawatts of power. Farm wide dynamics refers to the collective behaviour of multiple wind turbines that cumulatively produces effects that cannot simply be modelled by summing the behaviours of individual machines. Many facets within this topic have been addressed singly in the literature and are widely used in industry; while others are less understood. It is here asserted that the farm wide dynamic approach is essential for the optimum design, power production, management, and profitability of a wind farm. The inter-relationships between the subcomponents of farm siting, power production, and maintenance are illustrated and discussed. A simple weighting system to assist in the prioritization of the critical dynamic elements is proposed.
