INTEGRATION OF WIND FARMS INTO WEAK AC GRIDS [PDF]
, 2020 Large wind farms are usually located in remote and offshore areas. High voltage transmission systems that have long transmission distances are used to deliver the wind power to main grids. Weak AC grids have high impedance, low short circuit ratio (SCR) and/or low inertia compared to strong AC grids.

Robust Delay Compensation Strategy for LCL-Type Grid-Connected Inverter in Weak Grid
IEEE Access, 2022 Capacitor-current-feedback active damping has been widely adopted in digitally controlled LCL-type grid-connected inverters (GCIs). However, their digital control delay causes the system stability to deteriorate within a negative damping range ...

On Stability of Voltage Source Inverters in Weak Grids
IEEE Access, 2018 As the number of inverters increases in the power grid, the stability of grid-tied inverters becomes an important concern for the power industry. In particular, a weak grid can lead to voltage fluctuations at the inverter terminals and consequently cause inverter instability.

Improved Fractional-order Damping Method for Voltage-controlled DFIG System Under Weak Grid
Journal of Modern Power Systems and Clean Energy, 2022 When a doubly-fed induction generator (DFIG) is connected to a weak grid, the coupling between the grid and the DFIG itself will increase, which will cause stability problems. It is difficult to maintain the tracking accuracy and ro-bustness of the phase-
