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

A Linearized OPF Model With Reactive Power and Voltage Magnitude: A Pathway to Improve the MW-Only DC OPF
TL;DR: In this paper, a linearized and convergence-guaranteed optimal power flow (OPF) model with reactive power (Q ) and voltage magnitude (v ) is proposed, and the locational marginal price (LMP) is closer to the AC OPF solution than the DC OPF method.

A Linear-Programming Approximation of AC Power Flows
TL;DR: Novel linear-programming models that incorporate reactive power and voltage magnitudes in a linear power flow approximation are proposed, built on a polyhedral relaxation of the cosine terms in the AC equations as well as Taylor approximations of the remaining nonlinear terms.

Cyber-physical attacks in power networks: Models, fundamental limitations and monitor design
TL;DR: In this paper, a unified framework and advanced monitoring procedures are proposed to detect and identify network components malfunction or measurements corruption caused by an omniscient adversary, which generalizes the prototypical stealth, (dynamic) false-data injection and replay attacks.

Comparative analysis of existing models for power-grid synchronization
TL;DR: In this paper, a comparative analysis of three leading models used to study synchronization dynamics in power-grid networks is presented, showing that each of these models can be derived from first principles within a common framework based on the classical model of a generator, thereby clarifying all assumptions involved.
