Wind generation penetration levels are increasing in power systems across the world. Along with transmission connected wind farms, distribution connected wind farms are becoming more prevalent in power systems. How these distribution connected farms control reactive power is of concern to the transmission system operator. This paper examines a hybrid system, where the transmission system is modeled with a significant penetration level of radial distribution feeders connected to a collection of small wind farms. By varying control strategies at the distribution farms the impacts of the reactive power control strategy implemented by the wind farms are observed. It aims to show that the additional impedance of the distribution system will have unintended consequences on the transmission system and the application of voltage control is less critical.
