High-Performance Computing for Real-Time Grid Analysis and Operation
TL;DR: In this article, power system computation software tools are traditionally designed as serial codes and optimized for single-processor computers They are becoming inadequate in terms of computational efficiency for the ever increasing complexity of the power grid The power grid has served us remarkably well but is likely to see more changes over the next decade than it has seen over the past century.

Voltage collapse preventive control - a new method
A.C. Andrade,F.P.M. Barbosa +1 more
TL;DR: Numerical experiments using standard IEEE 14 and 57 bus systems show that the proposed method can compute the voltage collapse point using several different scenery of load increase.

Transient stabilization of multimachine power systems: Towards a global decentralized solution
TL;DR: The main contribution of this paper is the proof that, using local measurements available with existing technology, it is possible to transform the previous centralized controller into a truly decentralized one—provided the derivative of the active power at each generator can be suitably estimated.

Considerations on the characteristic impedance of periodically grounded multiconductor transmission lines
TL;DR: In this paper, a nonsymmetric algebraic Riccati equation is solved with both a factorization and an iterative method for a multiconductor transmission line with one conductor periodically grounded.

Controlling Chaos and Bifurcation of Subsynchronous Resonance in Power System
Ahmad Harb,Mohammad S. Widyan +1 more
TL;DR: Linear and nonlinear state feedback controllers are proposed to control the bifurcation of a new phenomenon in power system, this phenomenon of electro-mechanical interaction between the series resonant circuits and torsional mechanical frequencies of the turbine generator sections, which known as Subsynchronous Resonance (SSR) as discussed by the authors.
