The scope of the project is to evaluate the impact of the POD control on the existing control and mechanical performance of the offshore wind turbines. It includes developing appropriate model for the interactions between the offshore wind turbine and grid using Matlab Simulink based simulation package. The model will be validated using available simulation and test data that can be obtained from other sources. A POD will be incorporated to suppress the relevant oscillation frequency of this model. This investigation will then be extended to assess possible impact of POD control actions on the existing control systems and mechanical performance of the turbines.
The main objective of the project is to investigate if there are unfavourable interactions between the POD power modulation actions on offshore wind turbine control performance. Should such interactions exist, this project will further detail and suggest where available suitable mitigations to these issues. A final report comprising these findings will be made available to inform further developers in meeting the requirements as recorded within their bilateral agreements. In a longer term, the developed model for wind turbine-gird interactions could be applied to explore control strategy options including their integration with HVDC and energy storage connections and their broader ranges of interaction with power systems.
