• Nonlinear Analysis for the Three-Phase PLL: A New Look for a Classical Problem 

      Bravo M.; Garcés, Alejandro; Montoya O.D.; Baier C.R. (Institute of Electrical and Electronics Engineers Inc., 2018)
      In this paper we investigate the dynamics of the classic synchronous reference frame phase-locked-loop (PLL) from a non-linear perspective. First, we demonstrate the nonlinear differential equations that describe the PLL ...
    • Passivity-based control of islanded microgrids with unknown power loads 

      Avila Becerril, Sofia; Espinosa Pérez, Gerardo; Montoya, Oscar Danilo; Garcés, Alejandro (Cartagena de IndiasCampus TecnológicoIngeniería Eléctrica, 2020-10-12)
      In this paper, the control problem of microgrids (MGs)operating in islanded mode is approached from a passivity-based control perspective. A control scheme is proposed that, relying only on local measurements for the power ...
    • Stability Analysis of Single-Phase Low-Voltage AC Microgrids with Constant Power Terminals 

      Montoya O.D.; Garces A.; Avila-Becerril S.; Espinosa-Pérez, G.; Serra F.M. (Institute of Electrical and Electronics Engineers Inc., 2019)
      This express brief presents the stability analysis of single-phase microgrids (SP-MG) operating under master-slave connection with constant power terminals. The SP-MG is composed of linear elements, nonlinear loads, and ...
