Offshore Wind Energy System with DC Transmission Discrete Mass: Modeling and Simulation

This chapter presents a simulation of a study to improve the ability of an offshore wind system to recover from a fault due to a rectifier converter malfunction. The system comprises: a semi-submersible platform; a variable-speed wind turbine; a PMSG; a 5LC-MPC; a fractional PI controller using the Carlson approximation. Recovery is improved by shielding the DC link of the converter during the fault using as further equipment a redox vanadium flow battery, aiding the system operation as desired in the scope of Energy 4.0. Contributions are given for: (i) the fault influence on the behavior of voltages and currents in the capacitor bank of the DC link; (ii) the drivetrain modeling of the floating platform by a three-mass modeling; (iii) the vanadium flow battery integration in the system.

“…Moreover, vector control technique with proportionalintegral (PI) controllers or direct control technique with switching tables can be selected as the inner loop control schemes of the converters [17][18][19]. In [20] and [21], a novel control scheme based on fractional-order controllers has been proposed. The two articles have shown that the power quality of the converters can be improved by using such control strategy.…”

To ensure the proper operation of power system, some independent system operators have specified that wind power plants should be able to participate in frequency control. This paper presents a combined control scheme exploiting the self-capability of PMSG based wind turbine to provide primary frequency response. In this scheme, the wind turbine operates in de-loading mode to obtain the power reserve under normal condition.On detecting frequency deviation, the proposed control strategy can not only utilize the power reserve and the kinetic energy of rotor for frequency regulation by adjusting the rotor speed, but employ the energy stored in DC capacitor to provide additional frequency support by slightly changing the DC-link voltage as well. The simulation results reveal that the wind turbines with the proposed method can improve frequency performance under both constant wind speed condition and variable wind speed condition.
