MATPOWER: Steady-State Operations, Planning, and Analysis Tools for Power Systems Research and Education
TLDR
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.Abstract:
MATPOWER is an open-source Matlab-based power system simulation package that provides a high-level set of power flow, optimal power flow (OPF), and other tools targeted toward researchers, educators, and students. The OPF architecture is designed to be extensible, making it easy to add user-defined variables, costs, and constraints to the standard OPF problem. This paper presents the details of the network modeling and problem formulations used by MATPOWER, including its extensible OPF architecture. This structure is 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. Simulation results are presented for a number of test cases comparing the performance of several available OPF solvers and demonstrating MATPOWER's ability to solve large-scale AC and DC OPF problems.read more

Sparse Malicious False Data Injection Attacks and Defense Mechanisms in Smart Grids
TL;DR: It is found that random undetectable attacks can be accomplished by modifying only a much smaller number of measurements than this value, and this greedy algorithm has almost the same performance as the brute-force method, but without the combinatorial complexity.
