This paper presents a new nonlinear backstepping controller for a direct-driven permanent magnet synchronous generator-based wind turbine, which is connected to the power system via back-to-back converters. The proposed controller deals with maximum power point tracking (MPPT) in normal condition and enhances the low-voltage ride-through (LVRT) capability in fault conditions. In this method, to...

Wind energy is the fastest growing renewable energy source. Double Fed Induction Generator, which is predominantly used nowadays in wind turbines, is very sensitive to grid disturbances and can damage the power electronic converters due to over voltage and over current. Therefore, protection elements which disconnect the machine during fault are very essential. But, in such cases, the reliabili...

With the increasing penetration level of wind turbine generators (WTGs) integrated into power system, WTGs are enforced to aid network and fulfill low voltage ride through (LVRT) requirements during faults. To enhance LVRT capability permanent magnet synchronous generator (PMSG)-based WTG connected grid, this paper presents a novel coordinated control scheme named overspeed-while-storing for PM...

For the extraction of wind energy through a doubly-fed induction generator (DFIG), low voltage ride (LVRT) is an essential technical requirement specified by transmission system operator (TSO). Under grid fault condition, DFIG should remain in connection with for certain minimum period and offer reactive power support as required TSO. A cooperative control scheme consisting hardware solution su...

Abstract Given the “carbon neutralization and carbon peak” policy, enhancing low voltage ride-through (LVRT) capability of wind farms has become a current demand to ensure safe stable operation power systems in context possible severe threat large-scale disconnection caused by farms. Currently, research on LVRT mainly focuses suppressing rotor providing reactive support, while impact active out...
