Susceptibility of Large Wind Power Plants to Voltage Disturbances — Recommendations to Stakeholders
Journal of Modern Power Systems and Clean Energy, 2022 Sufficient fault ride-through (FRT) of large wind power plants (WPPs) is essential for the operation security of transmission system. The majority of studies on FRT do not include all disturbances originating in the transmission system or the ...

Enhancing Data Center Low-Voltage Ride-Through
CoRRData center loads have expanded significantly in recent years. Compared to traditional loads, data centers are highly sensitive to voltage deviations and thus their protection mechanisms trip more proactively during voltage fluctuations. During a grid fault, simultaneous tripping of large-scale data centers can further destabilize the transmission ...

LVRT Control Strategy for Asymmetric Faults of DFIG Based on Improved MPCC Method
IEEE Access, 2021 In the case of asymmetric fault, the modern new power grid requires that the doubly-fed induction generator (DFIG) still has good low voltage ride-through (LVRT) capabilities. To solve this problem, a low voltage ride-through control strategy based on an

Addressing Economic Insecurities Can Improve Patient‐Reported Outcomes in Lupus
Arthritis Care &Research, EarlyView.Objective Economic insecurities, such as food, housing, transportation, and financial challenges, are modifiable risk factors and influence patient‐reported outcomes (PROs) in systemic lupus erythematosus (SLE). We examined the following: (1) associations between economic insecurities and PROs, and (2) the impact of screening and addressing economic ...
