A composable method for real-time control of active distribution networks with explicit power setpoints. Part I: Framework
TL;DR: The proposed method for the explicit control of the grid status is based on a common abstract model characterized by the main property of being composable, which means subsystems can be aggre-gated into virtual devices that hide their internal complexity.

A primal-dual interior point method for optimal power flow dispatching
TL;DR: In this article, a primal-dual interior point method for optimal power flow dispatching (OPFD) has been proposed, which is a direct extension of primal dual methods for linear programming.

Stealth false data injection using independent component analysis in smart grid
TL;DR: It is shown that when the system dynamics are small and can be approximated linearly, linear independent component analysis (ICA) can be applied to estimate the Jacobian matrix multiplied by the eigenvectors of the covariance matrix of the state variables.

Optimization Strategies for the Vulnerability Analysis of the Electric Power Grid
TL;DR: In this article, power grid vulnerability analysis can be studied as a bilevel mixed integer nonlinear programming problem, which can be exploited to avoid nonlinearity and approximate the original problem as a pure combinatorial problem.
