Evaluation of the frequency response of AC transmission based offshore wind farms
(InTech Europe, 2011)
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 ...
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 ...
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 ...
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, ...
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 ...
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 ...
Power Balancing in Cascaded H-Bridge and Modular Multilevel Converters Under Unbalanced Operation: A Review
(IEEE, 2021)
Multilevel Voltage-Source Converters (VSC) based on modular structures are envisioned as a prominent alternative for grid and industry applications. Foremost among these are the Cascaded H-Bridge (CHB) and the Modular ...
Experimental comparative study between MPPT, hybrid P&O and fuzzy control for a small wind turbine applicationEstudio comparativo experimental entre MPPT, P&O híbrido y un control basado en lógica difusa para una comparación experiemental de minieólica
(Federacion de Asociaciones de Ingenieros Industriales de Espana, 2021)
This study focuses on a comparison between different maximum power extraction controls for a small wind turbine application. In this case, a vertical axis wind turbine (VAWT) coupled to a permanent magnet synchronous ...
