Predictive power control for electric vehicle charging applications 

Gil-González, Walter; Serra, Federico; Dominguez, Juan; Campillo, Javier; Montoya, Oscar (2020-12-01)
This paper presents a direct predictive power control (DPPC) design for vehicle charging applications. The proposed control design allows working in the Park's reference frame avoiding the usage of the phase-lock loops, ...

Intelligent fault detection system for microgrids 

Cepeda, Cristian; Orozco-Henao, Cesar; Percybrooks, Winston; Pulgarín-Rivera, Juan Diego; Montoya, Oscar Danilo; Gil-González, Walter; Vélez, Juan Carlos (2020-03-06)
The dynamic features of microgrid operation, such as on-grid/off-grid operation mode, the intermittency of distributed generators, and its dynamic topology due to its ability to reconfigure itself, cause misfiring of ...

Global stabilization of a reaction wheel pendulum: A discrete-inverse optimal formulation approach via a control lyapunov function 

Montoya, Oscar Danilo; Gil-González, Walter; Dominguez-Jiménez, Juan A.; Molina-Cabrera, Alexander; Giral-Ramírez, Diego A. (2020-10-26)
This paper deals with the global stabilization of the reaction wheel pendulum (RWP) in the discrete-time domain. The discrete-inverse optimal control approach via a control Lyapunov function (CLF) is employed to make the ...

Second-order cone approximation for voltage stability analysis in direct-current networks 

Montoya, Oscar Danilo; Gil-González, Walter; Molina-Cabrera, Alexander (2020-09-24)
In this study, the voltage stability margin for direct current (DC) networks in the presence of constant power loads is analyzed using a proposed convex mathematical reformulation. This convex model is developed by employing ...

Bilinear Control for Three-Phase Microgrids: A Proportional-Integral Passivity-Based Design 

Gil-González, Walter; Montoya, Oscar D.; Garcés, Alejandro (2020-07-30)
A bilinear PI control based on passivity theory for the adequate integration of distributed energy resources (DERs) in ac microgrids is presented in this paper. DERs are integrated into the grid by voltage source converters ...

Triangular Matrix Formulation for Power Flow Analysis in Radial DC Resistive Grids With CPLs 

Montoya, Oscar Danilo; Grisales-Noreña, L.F.; Gil-González, Walter (2019-07)
This brief briefly addresses the problem of power flow solution for direct-current (dc) networks with radial configuration and constant power loads (CPLs). It proposes a novel iterative method based on the upper triangular ...
