Strengthened SDP Relaxation for an Extended Trust Region Subproblem with an Application to Optimal Power Flow
Anders Eltved, Samuel Burer
We study an extended trust region subproblem minimizing a nonconvex function over the hollow ball intersected with a full-dimensional second order cone (SOC) co…

On the Robustness and Scalability of Semidefinite Relaxation for Optimal Power Flow Problems
Anders Eltved, Joachim Dahl, Martin S. Andersen
Semidefinite relaxation techniques have shown great promise for nonconvex optimal power flow problems. However, a number of independent numerical experiments have led to concerns a…
