Optimal Distributed Feedback Voltage Control under Limited Reactive Power
Guannan Qu, Na Li
In this paper, we propose a distributed voltage control in power distribution networks through reactive power compensation. The proposed control can (i) operate in a distributed fa…

On the Exponential Stability of Primal-Dual Gradient Dynamics
Guannan Qu, Na Li
Continuous time primal-dual gradient dynamics that find a saddle point of a Lagrangian of an optimization problem have been widely used in systems and control. While the global asy…

Online Optimization with Predictions and Switching Costs: Fast Algorithms and the Fundamental Limit
Yingying Li, Guannan Qu, Na Li
This paper studies an online optimization problem with a finite prediction window of cost functions and additional switching costs on decisions. We propose two gradient-based onlin…
