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…
Solving realistic security-constrained optimal power flow problems
Cosmin G. Petra, Ignacio Aravena
We present a decomposition approach for obtaining good feasible solutions for the security-constrained alternating-current optimal power flow (SCACOPF) problem at an industrial sca…
Another source of mesh dependence in topology optimization
Miguel A. Salazar de Troya, Geoffrey M. Oxberry, Cosmin G. Petra +1
The topology optimization community has regularly employed nonlinear programming (NLP) algorithms from the operations research community. However, these algorithms are implemented…
Statistical Treatment of Inverse Problems Constrained by Differential Equations-Based Models with Stochastic Terms
Emil M. Constantinescu, Noemi Petra, Julie Bessac +1
This paper introduces a statistical treatment of inverse problems constrained by models with stochastic terms. The solution of the forward problem is given by a distribution repres…
A Bayesian Approach for Parameter Estimation with Uncertainty for Dynamic Power Systems
Noemi Petra, Cosmin G. Petra, Zheng Zhang +2
We address the problem of estimating the uncertainty in the solution of power grid inverse problems within the framework of Bayesian inference. We investigate two approaches, an ad…
