Oscillation suppression strategy for direct drive wind power system based on voltage feedforward compensation for phase locked loop

open access: yesCSEE Journal of Power and Energy Systems
Due to the fact that the impedance of grid interacts with that of direct-drive wind turbines under weak grid, the direct-drive wind power system (DDWPS) possesses the risk of power oscillation.

MAF-PLL With Phase-Lead Compensator [PDF]

open access: yes, 2015
A basic approach to improve the filtering capability of a standard phase-locked loop (PLL) is to incorporate a moving average filter (MAF) into its control loop. This improvement, however, is at the cost of a slow transient response for the PLL, which is

A Comprehensive Review of Fault‐Current Limiter Technologies for Smart and Resilient Power Systems

open access: yesEnergy Science &Engineering, EarlyView.
This review compares superconducting, solid‐state, and hybrid fault‐current limiters (FCLs) for modern alternating current, direct current, and hybrid grids. It shows that optimal FCL selection depends on fault characteristics, network configuration, voltage level, protection coordination, and resilience requirements rather than on a universally ...
