“…In addition to DC capacitors, DC filters could also exist at the DC side of the transmission system for mitigating interference on the metallic telephone circuits, which could run adjacent to the DC links. The low harmonic content of currents and voltages in the VSC HVDC systems allow these filters to be small and simple [34].  Back-to-back HVDC systems [17,33]  Bipolar HVDC systems (bipole, bipole with metallic return, bipole with series-connected converters) [17,33,55]  Multi-terminal HVDC systems [17,33,55] Figure 3: HVDC system topologies…”

“…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 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 reactive power control loop can be set to control the reactive power flow according to the AC voltage or a reactive power reference value [33,34,63]. The control system can also consider the converter current limitations, as determined in the inner current control function [63].…”

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.
