“…(18) and (19), if a small variation occurs in v L Lrms (t) (e.g., v L Lrms (t) = V L L + |v s (t)|) and in δ (e.g., δ + |δ(t)|), it will directly impact v d (t) and i d (t) such to become, respectively, V d + |v d (t)| and I d + |î d (t)|. Therefore, controlling the variations magnitudes |v d (t)| and |v d (t)| results in regulating v L L (t) and δ.…”

“…The topology consists of a cascade connection of a non-controlled full-bridge diodes rectifier and a controlled DC-DC boost converter. A layout of similar nature is found in [18], which is a series connection of a full-bridge diodes rectifier and a DC-DC converter. Based on the proposed topology, the PWM controller is installed across the DC-DC converter.…”

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. Index Terms-diode-rectifier based HVDC, distributed PLLbased frequency control, offshore wind power integration, onshore AC fault, synchronization of wind turbine converters I. INTRODUCTION N Europe, onshore wind farms have already been well developed, and more attention has been drawn to offshore sites. Many large offshore wind farms will be developed in the ...

“…However, system performances under DC fault condition and fault recovery control method are not fully analyzed. A novel converter topology consisting of a series connection of 12-pluse diode rectifiers and VSC is proposed [24] for integrating an offshore wind farm with reduced cost and power loss. The dynamic performances under changing load and AC grid fault are investigated.…”

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.
