  • Dynamic converter control role configuration in grid of grids 

    Arévalo Soler, Josep; Nahalparvari, Mehrdad; Prieto Araujo, Eduardo; Gomis Bellmunt, Oriol; Norrga, Staffan (2023)
    Conference report
    Open Access
    The 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 

    Girona Badia, Jaume; Albernaz Lacerda Freitas, Vinícius; Prieto-Araujo, E.; Gomis Bellmunt, Oriol (2023)
    Conference report
    Restricted access - publisher's policy
    This 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 ...

  • MATLAB® modeling of a microgrid: towards a vision based on entropy balance 

    Khan, Ameer Abdullah; Martínez García, Herminio; Cuadras Tomàs, Àngel (AEDERMACP (European Association for the Development of Renewable Energies and Power Quality), 2023)
    Conference report
    Open Access
    A microgrid is defined as the link of consumer loads and decentralized energy assets with the ability to control the entire system as a whole. The modeling of an electromagnetic microgrid is discussed in this work to analyze ...

  • Efficient linearization of explicit multilinear systems using normalized decomposed tensors 

    Kaufmann, Christoph; Diego, Crespí de Valldaura Garcia; Lichtenberg, Gerwald; Pangalos, Georg; Yáñez, Carlos Cateriano (2023)
    Conference report
    Open Access
    Multilinear systems allow multiplications of states, inputs, and states with inputs, in all possible combinations. Recently, a new normalized decomposed tensor format of explicit multilinear models was introduced. This ...
