Latest Patents

Yini Zhou holds 1 patent for her invention titled "Ultra-fast frequency support for power electronic converters." This patent discloses a phase-locked loop optimization method and device that adds a phase step link to the traditional phase-locked loop structure. When the system frequency index exceeds the limit, a phase angle difference is instantly added to the phase-locked loop output angle. This allows the power electronic converter to quickly output power after a frequency drop, effectively improving the system frequency change rate and the frequency nadir. Importantly, the original phase-locked loop control structure is retained, ensuring that the design of the original controller parameters and dynamic performance are not compromised.
