The integration of offshore wind energy power system is a solution to reduce carbon emissions in the oil and gas sector. However, the intermittent profile of wind power generation can bring challenges of voltage/frequency fluctuations to the electrical grid of the platform. This article proposes a coordinated decentralized control used to mitigate voltage fluctuation in oil and gas platform caused by connection of wind power system through short- and long-umbilical cables. The proposed control is split into optimum loss control embedded in the wind power system control, and modified dynamic volt-var functions applied to active front-end variable frequency drives. The decentralized control is evaluated by means of simulation results considering a real case test bench of a typical Brazilian offshore platform with a wind power system of 10 and 50 MW, and umbilical cable of 12 and 150 km. The results indicate an effective contribution of the dynamic volt-var function in reducing voltage fluctuations for the three implemented wind power system configurations (i.e., 10; 50, and 50 MW/150 km).
