Transient Stability-Constrained OPF: Neural Network Surrogate Models and Pricing Stability

Manuel Garcia, Nicole LoGiudice, Robert Parker +1

A Transient Stability-Constrained Optimal Power Flow (TSC-OPF) problem is proposed that enforces frequency stability constraints using Neural Network (NN) surrogate models. NNs are…

Variable aggregation for nonlinear optimization problems

Sakshi Naik, Lorenz Biegler, Russell Bent +1

Variable aggregation has been largely studied as an important pre-solve algorithm for optimization of linear and mixed-integer programs. Although some nonlinear solvers and algebra…
