Journal ArticleDOI
MATPOWER: Steady-State Operations, Planning, and Analysis Tools for Power Systems Research and Education
TL;DR: The details of the network modeling and problem formulations used by MATPOWER, including its extensible OPF architecture, are presented, which are used internally to implement several extensions to the standard OPF problem, including piece-wise linear cost functions, dispatchable loads, generator capability curves, and branch angle difference limits.
Journal ArticleDOI
Malicious Data Attacks on the Smart Grid
TL;DR: Malicious attacks against power systems are investigated, in which an adversary controls a set of meters and is able to alter the measurements from those meters, and an optimal attack based on minimum energy leakage is proposed.
Journal ArticleDOI
Stability-constrained optimal power flow
TL;DR: A new methodology that eliminates the need for repeated simulation to determine a transiently secure operating point is presented, and dynamic equations are converted to numerically equivalent algebraic equations and integrated into the standard OPF formulation.
Proceedings ArticleDOI
Malicious Data Attacks on Smart Grid State Estimation: Attack Strategies and Countermeasures
TL;DR: The problem of constructing malicious data attack of smart grid state estimation is considered together with countermeasures that detect the presence of such attacks and an efficient algorithm with polynomial-time complexity is obtained.
Journal ArticleDOI
On Computational Issues of Market-Based Optimal Power Flow
TL;DR: In this article, trust region based augmented Lagrangian method (TRALM), step-controlled primal-dual interior point method (SCIPM), and constrained cost variable (CCV) OPF formulation are proposed.
