The development of a revolutionary design for transmission lines was recently introduced by shifting phase configurations and sub-conductors into “unconventional” arrangements that were geometrically optimized to maximize natural power. The objective of this paper is to study the electromagnetic transients that result from the simultaneous and sequential line energization and re-energization of th...Show More
The objectives of this paper are (i) to create a revolutionary design for transmission lines by shifting phase configurations and subconductors into “unconventional” arrangements that are geometrically optimized to maximize natural power, and (ii) to study electromagnetic transients owing to simultaneous and sequential line energization for unconventional high surge impedance loading (HSIL) lines ...Show More
This paper presents an algorithm for automatic load shedding as a Remedial Action Scheme (RAS) for power oscillation damping. The algorithm computes the exact amount of power for the load shedding in all buses and then detects the critical areas in the system. Therefore, the trip actions are only in the areas where are necessary. In addition to this, the RAS is equipped with an oscillation monitor...Show More
This paper introduces a holistic control approach applied to a grid-connected converter of a Battery Energy Storage System (BESS). The BESS is mainly used for power peak shaving, frequency supporting, and islanded operation mode which implies multiple control transitions depending on the operation mode. One existing challenge is related to the multiple tuning controllers for the grid-connected con...Show More
This paper proposes a light, flexible, and yet reliable multiparametric estimation algorithm for grid-connected voltage-source-converter-based systems. This approach combines the nonlinear least squares (NLSQ) fitting algorithm and the steady-state extended harmonic domain (EHD) model to take into account the harmonic effects. The EHD model is used to take advantage of the harmonic content of the ...Show More
Modern power systems with high penetration of renewable energies, such as wind and photovoltaic (PV), commonly experiment harmonic issues and in some cases this power quality problem leads to instability. To understand and study this phenomenon, small-signal models have been proposed; however, most of these models neglect the harmonic cross-coupling and the harmonics themselves. Consequently, the ...Show More
In this paper, a Multi Scale Recurrence Quantification Analysis (MSRQA) method is proposed to clustering harmonics on microgrid systems. MSRQA is composed by the Variational Mode Decomposition algorithm and the Recurrence Quantification Analysis (RQA). MSRQA decomposes a signal into a finite number of Mono-Component Signals (MCSs), then a feature extraction is carry out by the RQA on each MCS. Fin...Show More
The undesirable harmonic distortion produced by distributed generation units (DGUs) based on power-electronic inverters presents operating and power-quality challenges in electric systems. The level of distortion depends on the internal elements of the DGUs as well as on the characteristics of the grid, loads, and controls, among others. This paper presents a comprehensive method, focused on power...Show More
This paper details a technique in the time domain for the fast periodic steady state solution of systems with unified power flow controllers (UPFCs) incorporating three strategies for the practical representation of the UPFC commutation process. The computation of the periodic steady state solution of power systems with UPFCs including the proposed UPFC control strategies is efficiently obtained b...Show More
