Modelling and Control of a Fully Rated Converter Wind Turbine: Influence of Wind Generation on the Network Damping Nolan D. Caliao

The integration of wind power into the grid is now increasing at a significant pace which poses new challenges for power system operators which result to revisions of grid code requirements (GCR) in many countries. In these grid codes, fault ride through is of primary concern. The reason for this is that when large amount of wind energy is supplying the grid, they have to continuously supply power during fault to avoid large frequency deviation. There is even bigger challenge of wind power technology which to bear the same responsibilities for contribution to power system management as conventional synchronous generators does. This is a huge challenge, considering that wind power generation differs fundamentally from conventional generation in various ways Large scale connection of wind generation will influence the levels of damping of the power system. Inadequate network damping causes instabilities, the most common of which are shown in the electromechanical modes of oscillations.
