“…With such a response speed, the VSC is able to control transients and flicker, and keep the AC bus voltage constant, enhancing the transient stability of the system. Furthermore, through fast active and reactive power modulation, VSCs also provide effective damping for mitigating electromechanical oscillations [1,27,67,69,70,71]. [71] presents research results regarding the improvement of sub-synchronous torsional damping by VSC HVDC systems.…”

“…The comparatively new VSC HVDC transmission system has become possible with the development of Insulated-Gate Bipolar Transistors (IGBTs). The advanced controllability of the VSC HVDC technology has rendered the power transmission system capable of providing grid support to the connected AC networks [8][9][10]15,17,27,28]. Therefore, VSC HVDC transmission systems have experienced an increasingly wider range of applications [14,15,27,[29][30][31][32][33].…”

Voltage Source Converter (VSC) High Voltage Direct Current (HVDC) connection has become a new trend for long distance offshore wind power transmission. It has been confirmed by a lot of research that the maximum distance of a High Voltage Alternative Current (HVAC) sub-marine cable transmission system is limited due to surplus charging current of the cables. The VSC HVDC transmission system has the ability to overcome the limitation and offers other advantages over the HVAC transmission system. This paper is to review the VSC HVDC transmission technology and its application for offshore wind power integration. Firstly, the main components, configuration and topology of the VSC HVDC transmission system are described.Secondly, the converter control system and control strategies are presented. Following that, the capabilities of the VSC HVDC technology are described. Finally, the focus is given on the control methods of the VSC HVDC transmission system for fulfilling grid code requirements concerning Low Voltage Ride-Through (LVRT) and frequency regulation.

This paper investigates the dynamic performance of an active rectifier integrated into a wind park. The small changes in the DC current and the DC voltage are examined. The small variations are caused by the miniature power flow unbalance between the offshore wind park and the grid land. Internal DC collector is considered into the wind park, which provides an internal DC medium voltage bus. The AC output signal from the wind generator to the internal DC collector or DC bus is regulated through active rectifier. An active rectifier is a cascade connection of an uncontrolled full bridge diode rectifier and a controlled DC-DC boost converter. The small changes in the DC current and DC voltage due to power flow unbalance are analysed across the boost converter. The way in which these small variations affect the internal medium DC voltage is determined. The results are presented in the form of small signal transfer functions and are evaluated with MATLAB software.

“…These systems offer advantages over, the now mature, line commutated conversion methods used in classical HVDC; these advantages include improved AC side power quality performance without the need for large harmonic filters, ability to exchange both leading and lagging reactive power with the connected AC network, a non-reversing DC cable voltage, ability to feed into a dead load and smaller physical footprint [1] [2]. This paper is a postprint of a paper submitted to and accepted for publication in IET Generation, Transmission and Distribution and is subject to Institution of Engineering and Technology Copyright.…”
