Estudio de microgrids con interfases de convertidores de DC/AC
Get PDFEste artÃculo presenta un estudio de Microgrids con interfases de convertidores DC/AC. El artÃculo muestra los modos de operación de las Microgrids, además implementa un modelo de pequeña señal para el modo de operación aislado que permite estudiar la estabilidad del sistema. Finalmente se muestra el funcionamiento de la Microgrid en ambos modos de operación.Peer ReviewedPostprint (published version
New mathematical model of an inverter-based generator for stability studies of microgrid Systems
Get PDFA new mathematical model of a renewable generator, with a DC-AC interface, based on the concept of electrostatic machine is presented. This new model has a direct relationship between the DC and AC side. Moreover, it can be used for stability studies, taking into account the dynamics of the DC link and to find saturations and limits on the control signals.Peer ReviewedPostprint (author’s final draft
