    • Passivity-based control of islanded microgrids with unknown power loads 

      Avila Becerril, Sofia; Espinosa Pérez, Gerardo; Montoya, Oscar Danilo; Garces, 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 ...
    • PI-PBC Approach for Voltage Regulation in Cuk Converters with Adaptive Load Estimation 

      Montoya, Oscar; Gil-González, Walter; Garces, Alejandro; Sierra, Federico; Hernandez, J.C. (Cartagena de Indias, 2020-11-25)
      This paper proposes a proportional-integral passivity-based controller (PI-PBC) for supporting voltage in linear loads integrated with Ćuk converters. An adaptive load estimator is also employed to avoid current measurements ...
    • Stabilization of MT-HVDC grids via passivity-based control and convex optimization 

      Montoya, Oscar Danilo; Gil-Gonzalez, Walter; Garces, Alejandro; Serra, Federico; Hernandez, Jesus C. (Cartagena de Indias, 2021-04-30)
      This paper presents a model for stabilizing multi-terminal high voltage direct-current (MT-HVDC) networks with constant power terminals (CPTs) interfaced with power electronic converters. A hierarchical structure of ...
