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 ... -
Multi-agent system-based microgrid protection using angular variation: An embedded approach
(Elsevier, 2023-07)
Article
Accés restringit per política de l'editorialThis paper presents a new approach for protecting microgrids based on multi-agent systems and using the angular variation of currents. The multi-agent system was structured using a congregation organization with three ... -
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 ... -
Modular impedance modeling and stability analysis of hybrid AC/DC power systems with grid-forming and grid-following converters
(Institute of Electrical and Electronics Engineers (IEEE), 2023-01-01)
Article
Accés obertThe renewable energy resources integrating HVDC transmission systems, consisting of grid-following and grid-forming converters, have complex physical and control dynamic interactions. Although the impedance analysis method ... -
Novel control approach for a hybrid grid-forming HVDC offshore transmission system
(2020-04-03)
Article
Accés obertThis article describes a hybrid topology of high-voltage direct current (HVDC) for offshore wind farms using a series connection of a voltage source converter (VSC) and six-pulse diode rectifier (6P-DR). In this topology, ...
