Abstract
This paper explores the effects of wind farm power fluctuations on the power network. A dynamic simulation of a wind farm is performed and the spatial distribution of the wind turbines is considered. In a wind farm, many wind turbines feed power into the power grid at the point of common coupling. The power fluctuation from one turbine may cancel that of another, which effectively rectifies the power fluctuation of the overall wind farm. The effect of power fluctuations is quantified by measuring the flicker and the voltage variation for different case studies. We took a conservative approach to explore a wind farm that consists mainly of stall-controlled wind turbines with fixed frequency induction generators and a specified grid with a known short circuit capacity.
