Probabilistic assessment of wind generation effects on primary frequency response

In modern power systems wind is one of the main sources of renewable energy. This is especially true in the case of small systems where frequency issues are often observed. Due to this fact, limits are imposed on the maximum allowable wind penetration level, commonly based on a worst case scenario approach. This however does not give a complete picture of the overall system behavior. This paper proposes a more general approach. A Monte Carlo process is used and suitable indices are introduced in order to provide a comprehensive evaluation of the system dynamic response. Special attention is given on wind generation frequency support methods.
