11.1 Introduction

Voltage source converter–high voltage direct current (VSC-HVDC) connections have 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 AC (HVAC) submarine cable transmission system is limited, due in particular to surplus charging currents of the cables [1, 2]. The VSC-HVDC transmission system has the ability to overcome these limitations and offers other advantages over the HVAC transmission system [3–6]. It has been demonstrated that it is generally more efficient to transport power over an HVDC line for high power and distances larger than 100 km [1]. A commonly discussed technique for long-distance power transmission is to use a mixed AC/DC system with a medium-voltage AC (MVAC) collector network at the wind power plant (WPP) and an HVDC transmission line.

One of the most challenging issues in connecting an offshore WPP via a VSC-HVDC transmission line to a host power system is to fulfill the grid code requirements during power system faults. It is essential to ensure that offshore WPPs can meet the fault ride through (FRT) requirements specified by various grid codes. This ...
