This contribution introduces an efficient methodology for the fast periodic steady state solution of nonlinear power networks. It is based on the application of the Poincaré map to extrapolate the solution to the limit cycle through a Newton method based on a Discrete Exponential Expansion (DEE) procedure. The efficiency of the proposed DEE method is(More)
Wide area monitoring systems (WAMS) together with phasor measurement units (PMUs) are the key to implement wide area control systems (WACS). WACS are responsible of achieving different control objectives from signals and measurements taken of a wide area network. Control objectives can be focused on a large region of the network or part of it. Furthermore,(More)
This paper provides the comprehensive development procedures and mathematical model of an adjustable speed drive (ASD) for steady-state solutions, transient trajectories, and local stability based on a Floquet multiplier theory. A complete representation of the ASD is employed, which includes the dynamic equation of the dc link capacitor and the detailed(More)
This paper introduces an algorithm which dramatically reduces the computer effort required for the identification process of the transition matrix used for the fast steady state solution in the time domain on nonlinear power systems by extrapolation to the limit cycle. It is demonstrated that the proposed Enhanced Numerical Differentiation (END) Newton(More)
This paper presents a full model of a PV-Wind hybrid system implemented in a Real Time Digital Simulator (RTDS). The control strategies used for the connection of the hybrid system with the grid were developed and implemented in an Arduino Due board. The Hardware-in-the-loop (HIL) technique was used to interface the RTDS with the Arduino Due board. This(More)
This paper presents a comparative study of the application of Flexible AC Transmission System (FACTS) devices, as Thyristor Controlled Series Capacitor (TCSC), Static Synchronous Compensator (STATCOM) and Unified Power Controller (UPFC) on congestion management and voltage support in the area of the Istmo of Tehuantepec, Oaxaca, Mexico. The present work(More)
This paper proposes the use of the extended harmonic domain as modeling framework in the formulation of optimization problems to compute optimal designs in terms of specific characteristics of the system, such as power losses, cost, size, among others. The overall advantages of use this modeling tool are the explicit consideration of the switching process(More)
Flexible ac Transmission Systems (FACTS) devices have emerged in power system because of the development of power electronics components for high voltage and power. The FACTS devices provide higher controllability in power systems by means of power electronic devices. Several FACTS equipments have been already introduced for various applications worldwide,(More)
This paper presents the accelerated computation of the periodic steady state solutions of a nonlinear controlled microgrid system with multiple distributed generation units, using six Newton methods. The performance of the Newton methods are compared in terms of their numerical properties, computational effort and efficiency in order to know their(More)
