Query: Adversarially Robust Learning for Security-Constrained Optimal Power
  Flow   In recent years, the ML community has seen surges of interest in both
adversarially robust learning and implicit layers, but connections between
these two areas have seldom been explored. In this work, we combine innovations
from these areas to tackle the problem of N-k security-constrained optimal
power flow (SCOPF). N-k SCOPF is a core problem for the operation of electrical
grids, and aims to schedule power generation in a manner that is robust to
potentially k simultaneous equipment outages. Inspired by methods in
adversarially robust training, we frame N-k SCOPF as a minimax optimization
problem - viewing power generation settings as adjustable parameters and
equipment outages as (adversarial) attacks - and solve this problem via
gradient-based techniques. The loss function of this minimax problem involves
resolving implicit equations representing grid physics and operational
decisions, which we differentiate through via the implicit function theorem. We
demonstrate the efficacy of our framework in solving N-3 SCOPF, which has
traditionally been considered as prohibitively expensive to solve given that
the problem size depends combinatorially on the number of potential outages.
