Voltage rise mitigation in distribution networks using generators automatic reactive power controls

Distributed Generation is growing at important rates due to several reasons, including, in some countries, the strong penetration of renewable generating plants. Voltage rise is a considerable problem that prevents generators from injecting more active power into distribution networks. After a review of recently proposed mitigation techniques, a voltage rise mitigation technique is presented. The technique is based on a coordinated reactive power control of the distributed generators which takes into account the capability limits of the generators. It is suitable for utilization in distribution networks equipped with or without a dedicated communication infrastructure.
