The interconnection of offshore wind power plants with oil and gas installations can bring environmental as well as financial benefits. Such an interconnected system is still not in operation, but the combination of high reliability requirements and relatively low system inertia can pose significant technical challenges, especially in the design of an adequate overall control strategy. This paper investigates the robustness of an offshore power system including an offshore wind power plant and O&G-platforms with focus on the active power management. State-of-the-art wind power plant ancillary services such as inertia emulation and power-frequency control are evaluated as a measure for improving the robustness of the offshore power system. In particular, the possible benefits deriving from wind turbine support are assessed on a reference case study by numerical simulations.
