“…Methods have been proposed in literature for stabilizing the wind power output, mainly in large-scale integration. The vast majority of these methods are based on energy storage systems (ESSs) [8]- [12], as in addition to smooth the generation, they provide a backup energy for renewable generation. In [8] a short-term ESS is used to smooth out fast wind power changes.…”

“…In [11], this hybrid system is composed of a battery and a superconducting flywheel. The authors of [12] propose a method for virtual inertia capable of reducing the energy storage rating when the inertia response and primary frequency response are deployed. However, inserting ESS in offshore platforms is challenging due to area, volume, and weight limitations and application in harsh environments.…”

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 paper 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 MW and 50 MW, and umbilical cable of 12 km 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 MW/12 km; 50 MW/12 km and 50 MW/150 km).INDEX TERMS Coordinated control, offshore wind, O&G platform, voltage fluctuations, volt-var function.

Renewable energy resources emerge as a sustainable alternative to augmenting the energy supply of floating production storage and offloading (FPSO) platforms. However, the increased generation at FPSO based on converter-interfaced energy decreases the system-equivalent inertia constant, which becomes more susceptible to frequency deviations. This paper proposes and evaluates the combined frequency-voltage-var control performance to mitigate frequency variation in a typical FPSO unit with penetration of floating wind energy generation. The control functions are communication-free and embedded in the active front-end variable frequency drives (AFE-VFDs), which are installed on the FPSO and have the primary function of controlling the speed of water injection pumps. The FPSO electrical power system model is developed in MATLAB/Simulink®. Comparative results obtained from the AFE-VFD equipped with volt-var, freq-var, and combined freq-volt-var functions are shown to highlight the proposed solution merits. The results have shown a conflicting behavior with the frequency and voltage deviation improvement associated with absorption and injection of reactive power, respectively. Accordingly, the frequency-volt-var prioritizes frequency deviations during heavy transient events and voltage deviations during regular operation.
