  • Maximum current injection method for grid-forming inverters in an islanded microgrid subject to short circuits 

    Miret Tomàs, Jaume; Castilla Fernández, Miguel; Velasco García, Manel; Guzmán Solà, Ramon; García de Vicuña Muñoz de la Nava, José Luis (2023-02-03)
    Article
    Accés obert
    In islanded microgrids, when a short circuit or a sudden overload occurs, it provokes an abrupt increment in the currents supplied by the generation nodes, which feed the load collaboratively. This is particularly challenging ...
