Behavior of the three-phase induction motor with spiral sheet rotor
(2009-03)
Article
Open AccessImprovements in torque at low currents using a rotor with spiral sheets are analyzed. Several rotors and stators have been built combining different constructive and mechanical characteristics of the related elements: ... -
Reduced-order models of squirrel-cage induction generators for fixed-speed wind turbines under unbalanced grid conditions
(2016-06)
Article
Open AccessThis paper develops a study of reduced-order models for squirrel-cage induction generators used in the fixed-speed wind turbines. The squirrel-cage of these generators must be modeled with a double-cage for accuracy purposes. ... -
Integration of cold ironing and renewable sources in the Barcelona smart port
(2019-11)
Article
Restricted access - publisher's policyCold ironing, which is the procedure of supplying shoreside electrical power to a ship at berth when its engines are turned off, arises as the eco-friendly way to deliver power to ships while they are berthed in ports, ... -
A survey and evaluation of the potentials of distributed ledger technology for peer-to-peer transactive energy exchanges in local energy markets
(2019-09)
Article
Restricted access - publisher's policyTheunpredictability and intermittency introduced by Renewable Energy Sources (RESs) in power systems may lead to unforeseen peaks of energy production, which might differ from energy demand. To manage these mismatches, a ... -
Doubly fed induction generator-based variable-speed wind turbine: proposal of a simplified model under a faulty grid with short-duration faults
(2019-08)
Article
Open AccessThe aim of this study is to provide a simplified model of a variable-speed wind turbine (VSWT) with the technology of a doubly-fed induction generator (DFIG) which operates under faulty grid conditions. A simplified model ... -
Initialization of DFIG wind turbines with a phasor-based approach
(2019-03)
Article
Open AccessThe objective of this paper is to propose a simple approach to solve the steady state of a wind turbine (WT) equipped with a doubly-fed induction generator (DFIG) which can be used to initialize dynamic studies of the ... -
Analysis of the performance of MMC under fault conditions in HVDC-based off-shore wind farms
(Institute of Electrical and Electronics Engineers (IEEE), 2016-04)
Article
Open AccessThis paper analyzes the behavior of a modular multilevel converter-high-voltage direct-current (MMC HVDC)-connected offshore wind power plant (WPP) during dc faults. For that purpose, detailed models of the dc cable, MMC ... -
Prognosis of water quality sensors using advanced data analytics: Application to the barcelona drinking water network
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-03-01)
Article
Open AccessWater Utilities (WU) are responsible for supplying water for residential, commercial and industrial use guaranteeing the sanitary and quality standards established by different regulations. To assure the satisfaction of ... -
Voltage sag influence on controlled three-phase grid-connected inverters according to the Spanish grid code
(2020-02-03)
Article
Open AccessTo ensure the safe operation of the grid, there are some requirements to be taken into consideration to connect power converters. During abnormal conditions – e.g. during voltage sags –, the control of the converters is a ... -
TS-MPC for autonomous vehicles Including a TS-MHE-UIO estimator
(Institute of Electrical and Electronics Engineers (IEEE), 2019-07-01)
Article
Open AccessIn this paper, a novel approach is presented to solve the trajectory tracking problem for autonomous vehicles. This approach is based on the use of a cascade control where the external loop solves the position control using ... -
Resilient distributed model predictive control for energy management of interconnected microgrids
(2019-01-01)
Article
Open AccessDistributed energy management of interconnected microgrids that is based on Model Predictive Control (MPC) relies on the cooperation of all agents (microgrids). This paper discusses the case in which some of the agents ... -
Adaptive PI control with robust variable structure anti-windup strategy for systems with rate-limited actuators: application to compression systems
(2020-03-01)
Article
Open AccessIn this paper, an adaptive proportional-integral (PI) control strategy for nonlinear systems with constrained actuators is discussed. In particular, a variable-structure anti-windup strategy that can be retro fitted onto ...
