The impact of electricity tariffs on optimal production scheduling
(2023)
Text en actes de congrés
Accés obertEnergy costs can represent a large portion of the total production costs, and therefore, any changes in electricity tariffs can have a significant impact on profitability. This paper analyses how different types of electricity ... -
Comparative analysis of fault detection and classification techniques for HVDC grids protection
(The Institution of Engineering and Technology (IET), 2020)
Text en actes de congrés
Accés restringit per política de l'editorialDealing with high short-circuit currents with a fast rise rate in Voltage Source Converters (VSCs) still poses as a challenge for High Voltage Direct Current (HVDC) multiterminal system (MTDC) reliability. Several fault ... -
Denoising of online resistance measurements of power connectors for IoT applications
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Comunicació de congrés
Accés obertThe increasing development of the Internet of Things (IoT) allows the acquisition of key parameters to develop health monitoring strategies for power transmission systems. These IoT devices need to incorporate sensors for ... -
Models and methods for steady-state analysis of radial multi-energy grids and microgrids
(2023)
Text en actes de congrés
Accés obertThe interconnection between different energy networks leads to interdependencies that require suitable models and methods for their analysis. This paper presents appropriate models and methods for integrated and steady-state ... -

(Haus der Technik (HDT), 2023)
Comunicació de congrés
Accés restringit per política de l'editorialThe GENIUS project aims at investigating the use of innovative digital tools to ease the ecological transition of industrial facilities. One of these technologies is a battery pack based on 2nd life batteries from electric ... -
Modelling and simulation of power systems with grid-connected converters in OpenModelica
(2022)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper analyses the capabilities of the Open-Modelica environment to perform electromagnetic transient (EMT) type simulations of power transmission systems with grid-connected converters. A power transmission system ... -
Modelling approaches of power systems considering grid-connected converters and renewable generation dynamics
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper presents a comparative analysis of several modelling approaches of key elements used in simulations of power systems with renewable energy sources. Different models of synchronous generators, transmission lines, ... -
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 ...
