Strong NP-hardness of AC power flows feasibility
Daniel Bienstock, Abhinav Verma
We present a rigorous proof of strong NP-hardness of the AC-OPF problem.
Models for managing the impact of an epidemic
Daniel Bienstock, A. Cecilia Zenteno
In this paper we consider robust models for emergency staff deployment in the event of a flu pandemic. We focus on managing critical staff levels at organizations that must remain…
Two-sided linear chance constraints and extensions
Miles Lubin, Daniel Bienstock, Juan Pablo Vielma
We examine the convexity and tractability of the two-sided linear chance constraint model under Gaussian uncertainty. We show that these constraints can be applied directly to mode…
Robust Control of Cascading Power Grid Failures using Stochastic Approximation
Daniel Bienstock, Guy Grebla
Cascading failure of a power transmission system are initiated by an exogenous event that disable a set of elements (e.g., lines) followed by a sequence of interrelated failures (o…
Vulnerability Analysis of Power Systems
Taedong Kim, Stephen J. Wright, Daniel Bienstock +1
Potential vulnerabilities in a power grid can be exposed by identifying those transmission lines on which attacks (in the form of interference with their transmission capabilities)…
LP approximations to mixed-integer polynomial optimization problems
Daniel Bienstock, Gonzalo Munoz
We present a class of linear programming approximations for constrained optimization problems. In the case of mixed-integer polynomial optimization problems, if the intersection gr…
