Dynamic converter control role configuration in grid of grids
(2023)
Text en actes de congrés
Accés obertThe control role of power converters conforming an HVDC link is generally static, i.e. changing the control role of the power converters is not considered in the power system operation. In this paper a lab-scaled demonstration ... -
Limitations on the virtual inertia provision from grid-forming-connected renewable energy sources
(2023)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper addresses the limitations of virtual inertia provision from grid-forming interconnected renewable energy sources considering AC grid and resources dynamics. The instantaneous power that the grid-forming can ... -
Analysis of the contribution of a battery bank to voltage regulation in a distribution system
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Text en actes de congrés
Accés restringit per política de l'editorialDue to demand of higher power quality, reliability and efficiency levels, the penetration of distributed energy resources increased through the past years. Thus, several studies on the different types of electrical energy ... -
Analysis of harmonic distortion influence in a distributed synchronous generator
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Text en actes de congrés
Accés obertIn conventional electrical systems, the generators are located far from the load centers. However, considering the distributed generation, the impact of harmonic distortion in the generators cannot be neglected.Thus, this ... -
Phasor and EMT models of grid-following and grid-forming converters for short-circuit simulations
(2023)
Text en actes de congrés
Accés restringit per política de l'editorialPhasor models have been widely used in short-circuit simulations, in which system operators verify the behaviour of the grid over thousands of different contingencies. However, it is still unclear if phasor models can still ... -

(2023)
Text en actes de congrés
Accés restringit per política de l'editorialEste trabajo analiza la dinámica cero de inversores de fuente de corriente trifásicos alimentados desde una fuente de tensión y conectados a una carga resistiva local o a la red eléctrica. El análisis de la dinámica cero ... -
The impact of modular multilevel converter control on DC short-circuit currents of HVDC systems
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Text en actes de congrés
Accés restringit per política de l'editorialIn Modular Multilevel Converter (MMC) based DC systems, during the initial stage of a DC fault, the control system operates normally, inserting and bypassing submodules. Consequently, each MMC control technique would provide ... -
Proportional-resonant controller applied to modular multilevel converter for HVDC systems
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Text en actes de congrés
Accés restringit per política de l'editorialModular multilevel converters (MMC) are usually controlled by proportional-integral (PI) controllers. However, the PI controller has limitations such as the inability to track a sinusoidal reference without incurring ... -
Analysis and mitigation of harmonic distortion in distribution networks by an active filter
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Text en actes de congrés
Accés restringit per política de l'editorialAs a result of the presence of non-linear loads, it is possible to verify the increasing of harmonic distortion in electric power systems. When amplified, it can induce the resonance effect. This effect becomes more and ... -
NVH of PMSM evaluation under different working conditions in the drive system configuration
(2023)
Text en actes de congrés
Accés restringit per política de l'editorialNoise and vibrations produced by electric motors have gained particular importance lately as the market shifts to electrical vehicles (EVs). This work aims to evaluate the NVH (Noise, Vibration and Harshness) behaviour of ... -
