“…In [8], a voltage and frequency control is proposed, while communication for a centralized voltage control is required and all the wind turbines start-up from the beginning, with the synchronization process not being addressed. The fault ride-through performance and the operation with reduced diode rectifier filter are analyzed in [10], [11] using the same control strategy. In [13], umbilical ac cables are used to start-up the unidirectional DR-HVDC and a reactive power frequency droop control is presented.…”

The proposed control enables a large number of wind turbines to work autonomously to contribute to the offshore AC frequency and voltage regulation. The proposed control also provides automatic synchronization of the offline wind turbines to the offshore AC grid. Stability of the proposed frequency control is analyzed using root locus method. Moreover, an active dc voltage control of the onshore modular multilevel converter (MMC) is proposed to ride-through onshore AC fault, where the onshore MMC converter quickly increases the dc voltage by adding additional submodules in each phase, in order to rapidly reduce wind farm active power generation so as to achieve quick active power re-balance between the offshore and onshore sides. Thus the overvoltage of the submodule capacitor is alleviated during the onshore fault, reducing the possibility of system disconnection. Simulation results in PSCAD verify the proposed control strategy during start-up, synchronization and under onshore and offshore fault conditions.

“…However, the power loss of diodes at a steady-state operation is a considerable issue. A technical feasibility study of diode-rectifier and VSC inverter-based HVDC Link for offshore wind farms is proposed, loss analysis is carried out, and good fault ride-through performances to solid faults are obtained [22]. In addition, a distributed protection strategy has been designed, so each wind turbine reacts to the different faults using mainly local measurements.…”

A hybrid HVDC system that is composed of line commutated converter (LCC) at the rectifier side and voltage source converter (VSC) in series with LCC at the inverter side is studied in this paper. The start-up strategy, DC fault ride-through capability, and fault recovery strategy for the hybrid HVDC system are proposed. The steady state and dynamic performances under start-up, AC fault, and DC fault scenarios are analyzed based on a bipolar hybrid HVDC system. Furthermore, the immunity of the LCC inverter in hybrid HVDC to commutation failure is investigated. The simulation results in PSCAD/EMTDC show that the hybrid HVDC system exhibits favorable steady state and dynamic performances, in particular, low susceptibility to commutation failure, excellent DC fault ride-through, and fast fault recovery capability. Results also indicate that the hybrid HVDC system can be a good alternative for large-capacity power transmission over a long distance by overhead line.
