On the Optimality of Voltage Unbalance Attenuation by Inverters
Yifei Guo, Bikash C. Pal, Rabih A. Jabr
In this paper, we investigate the control of inverter-based resources (IBRs) for optimal voltage unbalance attenuation (OVUA). This problem is formulated as an optimization program…
Global Optimality of Inverter Dynamic Voltage Support
Yifei Guo, Bikash C. Pal, Rabih A. Jabr
This paper investigates the dynamic voltage support (DVS) control of inverter-based resources (IBRs) under voltage sags to enhance the low-voltage ride-through performance. We firs…
An Online Feedback-Based Linearized Power Flow Model for Unbalanced Distribution Networks
Rui Cheng, Zhaoyu Wang, Yifei Guo
The non-linearity and non-convexity of power flow models and the phase coupling challenge the analysis and optimization of unbalanced distribution networks. To tackle the challenge…
