Network-Cognizant Time-Coupled Aggregate Flexibility of Distribution Systems Under Uncertainties
Bai Cui, Ahmed Zamzam, Andrey Bernstein
Increasing integration of distributed energy resources (DERs) within distribution feeders provides unprecedented flexibility at the distribution-transmission interconnection. To ex…
Novel Region of Attraction Characterization for Control and Stabilization of Voltage Dynamics
Bai Cui, Ahmed Zamzam, Guido Cavraro +1
In this paper, we study the monitoring and control of long-term voltage stability considering load tap-changer (LTC) dynamics. We show that under generic conditions, the LTC dynami…
Balancibility: Existence and Uniqueness of Power Flow Solutions under Voltage Balance Requirements
Bowen Li, Bai Cui, Feng Qiu +1
In distribution systems, power injection variability due to growing penetrations of distributed energy resources (DERs) and dispatchable loads can lead to power quality issues such…
Counterexample to Equivalent Nodal Analysis for Voltage Stability Assessment
Bai Cui, Zhaoyu Wang
Existing literature claims that the L-index for voltage instability detection is inaccurate and proposes an improved index quantifying voltage stability through system equivalencin…
