Frequency behavior of grid with high penetration rate of wind generation

The increasing penetration rate of wind generation in power system is likely to change frequency behavior of grid. This is due to the specific response of these technologies to frequency changes. In order to better assess these changes, this paper focuses on the primary frequency control requirements. It now appears that an active contribution of wind power will be required to cope with high level of wind penetration. This paper also addresses the low contribution of wind generation to power system inertia. With high wind penetration, larger frequency changes are to be expected within the first few seconds following a grid contingency. To manage this, specific control loops should be implemented.
