An Alternating Trust Region Algorithm for Distributed Linearly Constrained Nonlinear Programs, Application to the Optimal Power Flow Problem

A novel trust region method for solving linearly constrained nonlinear programs is presented. The proposed technique is amenable to a distributed implementation, as its salient ingredient is an alternating projected gradient sweep in place of the Cauchy po ...

Network Flow Integer Programming to Track Elliptical Cells in Time-Lapse Sequences

Pascal Fua, Engin Türetken, Xinchao Wang, Carlos Joaquin Becker

We propose a novel approach to automatically tracking elliptical cell populations in time-lapse image sequences. Given an initial segmentation, we account for partial occlusions and overlaps by generating an over-complete set of competing detection hypothe ...

Security Constrained Unit Commitment With Dynamic Thermal Line Rating

Mario Paolone, Mostafa Nick, Omid Alizadeh Mousavi

The integration of the dynamic line rating (DLR) of overhead transmission lines (OTLs) in power systems secu- rity constrained unit commitment (SCUC) potentially enhances the overall system security as well as its technical/economic performances. This pape ...

Reachability-based Control Synthesis for Power System Stability

Maryam Kamgarpour

We present a nonlinear reachability framework for control of power system transients. The power system consists of synchronous generators, coupled by transmission lines and controlled HVDC links. The approach consists of characterisation of the region of a ...

Solving Stochastic AC Power Flow via Polynomial Chaos Expansion

Timm Faulwasser

The present contribution demonstrates the applicability of polynomial chaos expansion to stochastic (optimal) AC power flow problems that arise in the operation of power grids. For rectangular power flow, polynomial chaos expansion together with Galerkin p ...

Stable Simulation of Nonlinearly Loaded Lossy Transmission Lines with Time Marching Approach

Akiyoshi Tatematsu

A stable method for the analysis of lossy transmission lines with nonlinear loads is presented. The simulation employs the time marching (TM) method for solving the convolution equations in the time domain. To cope with the late-time instability of the TM ...
