Impact of Wind Farm Frequency Control on the Dynamic Response of the All-Island Irish System

This work originates from the observation that the current practice for wind farm frequency control mandated by the Irish Grid Code can lead to significant frequency oscillations in the system. With this regard, the paper proposes a variety of solutions to mitigate such an oscillatory response of wind farms and recover the frequency. The test case focuses on the trip of the largest HVDC interconnector and considers projected dispatch scenarios. The case study is based on a realistic although simplified dynamic model of the all-island Irish system.
