A Linear Branch Flow Model for Radial Distribution Networks and its Application to Reactive Power Optimization and Network Reconfiguration

Tianshu Yang, Ye Guo, Lirong Deng +2

This paper presents a cold-start linear branch flow model named modified DistFlow. In modified DistFlow, the active and reactive power are replaced by their ratios to voltage magni…

Virtual Homological Torsion of Closed Hyperbolic 3-manifolds

Hongbin Sun

In this paper, we will use Kahn-Markovic's almost totally geodesic surfaces to construct certain -injective 2-complexes in closed hyperbolic 3-manifolds. Such 2-complexes are…

An effective Lie--Kolchin theorem for quasi-unipotent matrices

Thomas Koberda, Feng Luo, Hongbin Sun

We establish an effective version of the classical Lie--Kolchin Theorem. Namely, let be quasi--unipotent matrices such that the Jordan Canonical F…
