To improve the low voltage ride-through capability of a permanent magnet synchronous generator (PMSG) grid-connected wind power system, a coordinated control method based on series dynamic braking resistors (SDBR) and a supercapacitor energy storage system (SCESS) is proposed. When the grid voltage drops, the SDBR connected in series across the grid will consume part of the unbalanced energy while raising the voltage at the grid-connected point, and the remaining unbalanced energy will be absorbed by the SCESS connected in parallel to the DC chain. Simulation results based on MATLAB/SIMULINK show that the SDBR-SCESS coordinated control strategy can effectively suppress the peak DC chain voltage and raise the voltage at the grid-connected point under fault, reduce the peak grid-connected current at the moment of fault removal, effectively shorten the recovery time of DC chain voltage and grid-connected current after fault removal, and improve the low voltage ride-through capability of the PMSG. Compared with the control based on SDBR or SCESS alone, the SDBR-SCESS coordinated control has a superior effect.
