Abstract
Control strategies for shutting down wind turbines are essential to improve the reliability of offshore wind energy under extreme wind conditions, which are expected to become more frequent in the North Sea area. The main objective of this thesis is to investigate and verify operational storm strategies for offshore wind farms. These strategies involve coordinated shutdowns of wind turbines to avoid disturbance in the utility grids. The proposed storm strategies are tested using a MATLAB Simulink wind farm model based on the Horns Rev I wind farm. The shutdown performance is tested with several proposed wind profiles to evaluate its correct operation in different meteorological conditions. The power and voltage responses resulting from different shutdown procedures are thoroughly analyzed and discussed to determine the optimal shutdown strategy for the specific case study. The chosen strategy aims to strike a balance between achieving a rapid shutdown of the entire wind farm, minimizing voltage drops, and ensuring a smooth transition to the idle state.
