“…This implies the capability of power control, since the active power is regulated by changing the phase of the AC converter voltage, whereas the reactive power is controlled by adjusting the magnitude of the AC converter voltage [33,34]. The active power control loop can be set to regulate the active power flow according to the DC voltage, the frequency variation or an active power reference value.…”

“…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]. One of the emerging application areas is the integration of remote RESs to the power system.…”

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.

“…In bipolar HVDC schemes, the midpoint of the dc capacitors is usually grounded to provide a reference voltage to the pole voltages [17], [18]. The midpoint is grounded either via a low-ohmic connection or through a reactor depending on the requirement, whether the bipole has to be able to be operated in monopolar mode or not [19].…”

“…The reactive power control loop can be set to control either the reactive power or the ac-side voltage. Either of these two modes can be selected independently at either end of the dc link [30]. Figure 2.1 shows a simple single line diagram of the basic components of a VSC-HVdc system.…”
