Analytical Modeling Approach to Study Harmonic Mitigation in AC Grids with Active Impedance at Selective Frequencies
(MDPI AG, 2018)
This paper presents an analytical model, oriented to study harmonic mitigation aspects in
AC grids. As it is well known, the presence of non-desired harmonics in AC grids can be palliated
in several manners. However, in ...
Evaluation of the frequency response of AC transmission based offshore wind farms
(InTech Europe, 2011)
Electric Technology in Wind Turbines from a Dialectic Perspective
(Philosophy Documentation Center, 2019)
Wind turbines have been used by many groups of humans for many centu-ries. Wind turbines have allowed groups of humans to perform many different tasks in the past (grinding grain, pumping water, etc.). However, ...
Frequency-Dependent Pi Model of a Three-Core Submarine Cable for Time and Frequency Domain Analysis
(MDPI AG, 2018-10-16)
In this paper, a Frequency-Dependent Pi Model (FDPi) of a three-core submarine cable is presented. The model is intended to be used for the representation of submarine cables in an Offshore Wind Power Plant (OWPP) scenario ...
Mathematical Model Equations in Stationary Reference Frame of Current Controls for Grid-Connected Converters
(Mondragon Unibertsitateko Zerbitzu Editoriala, 2019)
The grid-connected converter is a key element in many power electronic applications and technological devices which are commonly used nowadays. Wind turbines, photovoltaic generation, railway traction and grid-connected ...
Control of PWM rectifier under grid voltage dips
(PAN, 2009)
This paper investigates control structure for grid connected three-phase two-level Voltage Source Converter (VSC) under distorted grid voltage conditions. Grid voltage is distorted by balanced and unbalanced voltage dips ...
Design of a Solid-State Circuit Breaker for a DC Grid-Based Vessel Power System
(MDPI, 2019)
Electric propulsion and integrated hybrid power systems can improve the energy efficiency
and fuel consumption of different kinds of vessels. If the vessel power system is based on DC grid
distribution, some benefits ...
Analysis and Design Guidelines for Current Control Loops of Grid-Connected Converters Based on Mathematical Models
(MDPI AG, 2020)
Having a method for analyzing and designing regulators of controls that contain many current loops such as active filters is not a trivial task. There can be many parameters of regulators and filters that must be carefully ...
Reactive power limits of Cascaded H-Bridge STATCOMs in star and delta configuration under negative-sequence current withstanding
(Elsevier Ltd., 2022)
Flexible AC Transmission System devices (FATCS) and in particular Static Synchronous Compensators (STATCOM) play a key role in the evolution of the modern power grids to the future smart grids. The STATCOM is used in an ...
Reactive Power Limits of Single-Phase and Three-Phase DC-Link VSC STATCOMs under Negative-Sequence Voltage and Current
(IEEE, 2021)
This paper analyzes and compares the reactive power limits of single- and three-phase configured dc-link Voltage Source Converter (VSC) structures for Static Synchronous Compensator (STATCOM) to operate with negative-sequence ...
