Abstract
The EU countries are expected to achieve by 2020 a high demanding energy policy in relation to the level of integration of renewable in their existing transmission networks. This transformation will represent significant technical challenges for the EU system operators (TSOs). Based on the aforementioned, and forecasting the large amount of wind generation that is planned to be further integrated in the Portuguese transmission network, REN is performing detailed transient stability studies to ensure that this integration takes place in a safe and reliable way and does not compromise the stability of the grid. As part of this investigation REN is interested in evaluating the capacity of FACTS devices to provide reactive support during voltage dips and to help the voltage control in the grid. This article will focus on these particular aspects and presents some particular results from a case study.
