Optimal load-side control for frequency regulation in smart grids
Enrique Mallada, Changhong Zhao, Steven H. Low
Frequency control rebalances supply and demand while maintaining the network state within operational margins. It is implemented using fast ramping reserves that are expensive and…
Convex Relaxations and Linear Approximation for Optimal Power Flow in Multiphase Radial Networks
Lingwen Gan, Steven H. Low
Distribution networks are usually multiphase and radial. To facilitate power flow computation and optimization, two semidefinite programming (SDP) relaxations of the optimal power…
Convex Relaxation of Optimal Power Flow, Part II: Exactness
Steven H. Low
This tutorial summarizes recent advances in the convex relaxation of the optimal power flow (OPF) problem, focusing on structural properties rather than algorithms. Part I presents…
Convex Relaxation of Optimal Power Flow, Part I: Formulations and Equivalence
Steven H. Low
This tutorial summarizes recent advances in the convex relaxation of the optimal power flow (OPF) problem, focusing on structural properties rather than algorithms. Part I presents…
Distributed Optimal Power Flow Algorithm for Balanced Radial Distribution Networks
Qiuyu Peng, Steven H. Low
The optimal power flow (OPF) problem is fundamental in power system operations and planning. Large-scale renewable penetration in distribution networks calls for real-time feedback…
Decentralized Primary Frequency Control in Power Networks
Changhong Zhao, Steven Low
We augment existing generator-side primary frequency control with load-side control that are local, ubiquitous, and continuous. The mechanisms on both the generator and the load si…
