Compact representations of structured BFGS matrices
Johannes J. Brust, Zichao, Di +2
For general large-scale optimization problems compact representations exist in which recursive quasi-Newton update formulas are represented as compact matrix factorizations. For pr…
Recent Developments in Security-Constrained AC Optimal Power Flow: Overview of Challenge 1 in the ARPA-E Grid Optimization Competition
Ignacio Aravena, Daniel K. Molzahn, Shixuan Zhang +12
The optimal power flow problem is central to many tasks in the design and operation of electric power grids. This problem seeks the minimum cost operating point for an electric pow…
An Optimization algorithm for nonsmooth nonconvex problems with upper-C^2 objective
Jingyi Wang, Cosmin G. Petra
An optimization algorithm for nonsmooth nonconvex constrained optimization problems with upper-C2 objective functions is proposed and analyzed. Upper-C2 is a weakly concave propert…
A simplified nonsmooth nonconvex bundle method with applications to security-constrained ACOPF problems
Jingyi Wang, Cosmin G. Petra
An optimization algorithm for a group of nonsmooth nonconvex problems inspired by two-stage stochastic programming problems is proposed. The main challenges for these problems incl…
