Popis: The integration of increasing penetrations of renewable energy sources is one of the key drivers for the increased deployment of control and optimization on power systems. Much of this wind generation is connected to the distribution system, which presents a range of challenges to the operation of these networks, traditionally utilized solely for power delivery. This presentation describes a demonstration programme in Ireland which addresses key challenges in delivering high penetrations of wind energy in a cost effective and efficient manner. A trial of the advanced reactive power control capabilities of modern wind turbines, investigating how this resource can be better utilized from a distribution and transmission perspective is presented. The trial results indicate that the reactive power capabilities of modern wind turbines can be used for a range of objectives, such as loss reduction, local voltage control and reactive power export. It is important to note, however, these objectives may be conflicting, dependent on a range of factors such as wind power output, network impedance and the state of the transmission system.
