With the rapid development of offshore wind power

VSC-HVDC has become an effective way for large-scale offshore power delivery. However

this technology also puts forward higher requirements on DC network stability and fault ride-through capability. This paper focuses on large-scale multi-terminal offshore wind power flexible transmission system

reveals the propagation mechanism of fault disturbances in wind farms

converter stations and flexible systems

and systematically combs through the latest research progresses of offshore wind power delivery system to achieve low-/high-voltage fault ride-through. It is reviewed that the multidimensional coordination technique combining control optimization and hardware protection configuration can effectively enhance the fault ride-through capability of the wind power system and improve the stability of the system

and the superiority of the multidimensional coordination technique is verified through the discussion of typical offshore wind power VSC-HVDC engineering cases. Finally

for the future research of VSC-HVDC fault ride-through technology

it is necessary to focus on following breakthroughs: constructing a full-domain nonlinear dynamic model to deeply analyze the fault behavior mechanism

thus laying a rigorous mathematical foundation for the quantitative analysis of fault propagation paths and optimization of ride-through strategy; simultaneously

developing high-performance fault ride-through hardware equipment

focusing on the solution of engineering bottlenecks under extreme working conditions

and improving the system fault ride-through capability.
