Complex-valued sliding mode control of an induction motor
(2020)
Conference report
Restricted access - publisher's policyThree-phase induction motors admit a complex-valued space state representation. In this paper, this complex description is used to design a torque controller and a rotor flux observer based on sliding modes. The advantage ... -
On the vehicle state estimation benefits of smart tires
Conference report
Open AccessSmart tires are systems that are able to measure temperature, inflation pressure, footprint dimensions, and, importantly, tire contact forces. The integration of this additional information with the signals obtained from ... -
Non-Intrusive parameter identification of a three-phase rectifier based on an optimization approach
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Restricted access - publisher's policySix-pulse diode rectifiers are widely used in many power conversion systems. In this work a non-intrusive approach for parameter identification of such power device is presented and its accuracy and performance is evaluated ... -
Complex pole placement control for a three-phase voltage source converter
Conference report
Open AccessIn this work, a complex-valued controller for a three-phase VSC with an LC output filter is proposed. The system is first transformed into its complex representation with the consequent order reduction and simpler analysis. ... -
Practical design of a coherent ultra-dense WDM-PON with paired DFB lasers
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Restricted access - publisher's policyA coherent WDM-PON achieving ultra-dense spectral allocation is reported. The ONU at user premises is built of coherent transceivers with two paired low-cost DFB lasers, one as local oscillator and the other as transmitter, ... -
Centralized flexibility services for distribution system operators through distributed flexible resources
(Universidad Santiago de Cali, 2019)
Conference report
Open AccessUnder the context of smart grids within smart cities, increasing distributed generation, consumer empowerment and emerging flexibility services, distribution system operators could benefit by activating flexibility in ... -
A power sharing algorithm for a hybrid energy storage system based on batteries
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Open AccessThis paper presents a method to operate a hybrid Energy Storage System (ESS) based on a heterogeneous grouping of battery types. In particular, the system is composed by a lithium-ion battery pack and a lead-acid one. The ... -
System architecture for managing congestions in distributions grids using flexibility
(2019)
Conference lecture
Open AccessThe increased penetration of renewable, intermittent and distributed energy resources, flexible loads and EVs in the distribution network, has arisen congestion issues at medium and low voltage level. These flexible ... -
On resonance instabilities in VSCs connected to weak grids
(2019)
Conference report
Restricted access - publisher's policyThis paper addresses the oscillatory stability phenomena studied in the literature and reported by network operators in grid-connected VSC systems. Negative interactions have been observed at different frequencies in these ... -
Photovoltaic inverters with fault ride-through capability
(ISIE, 2009)
Conference lecture
Open AccessThis paper presents a new control strategy that allow the photovoltaic system operate under grid faults without overpass the rated current and assuring sinusoidal currents. In the classic control strategies used in ... -
Symmetrical and unsymmetrical voltage sag effects on the three-phase synchronous machine stability
(2009)
Conference lecture
Open AccessThis paper focuses on the effects of voltage sags, both symmetrical and unsymmetrical, on the three-phase Synchronous Machine (SM). Voltage sags on SM cause speed variations, current and torque peaks and hence may cause ...
