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. (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 ...

High impedance fault modeling and location for transmission line 

García, Jose Doria; Orozco-Henao, Cesar; Leborgne, Roberto; Montoya, Oscar Danilo; Gil-González c, Walter (2021-04-07)
A fault in a power system generates economic losses, security problems, social problems and can even take human lives. Therefore, it is necessary to have an efficient fault location strategy to reduce the exposure time ...

A Comparative Study on Power Flow Methods Applied to AC Distribution Networks with Single-Phase Representation 

Montoya, Oscar Danilo; Molina-Cabrera, Alexander; Hernández, Jesus C (2021-10-21)
This paper presents a comparative analysis of six different iterative power flow methods applied to AC distribution networks, which have been recently reported in the scientific literature. These power flow methods are (i) ...

On the Optimal Selection and Integration of Batteries in DC Grids through a Mixed-Integer Quadratic Convex Formulation 

Martin Serra, Federico; Montoya, Oscar Danilo; Alvarado-Barrios, Lázaro; Álvarez-Arroyo, Cesar; Chamorro, Harold R. (2021-09-24)
This paper deals with the problem of the optimal selection and location of batteries in DC distribution grids by proposing a new mixed-integer convex model. The exact mixed-integer nonlinear model is transformed into a ...

Sensorless Adaptive Voltage Control for Classical DC-DC Converters Feeding Unknown Loads: A Generalized PI Passivity-Based Approach 

Gil-González, Walter; Montoya, Oscar Danilo; Restrepo, Carlos; Hernández, Jesus C (2021-09-24)
The problem of voltage regulation in unknown constant resistive loads is addressed in this paper from the nonlinear control point of view for second-order DC-DC converters. The converters’ topologies analyzed are: (i) buck ...

Heuristic Methodology for Planning AC Rural Medium-Voltage Distribution Grids 

Montoya, Oscar Danilo; Serra, Federico Martin; De Angelo, Cristian Hernan; Chamorro, Harold R.; Alvarado-Barrios, Lazaro (2021-08-20)
The optimal expansion of AC medium-voltage distribution grids for rural applications is addressed in this study from a heuristic perspective. The optimal routes of a distribution feeder are selected by applying the concept ...

Voltage regulation of an isolated DC microgrid with a constant power load: a passivity-based control design 

Magaldi, Guillermo Luciano; Serra, Federico Martin; De Angelo, Cristian Hernán; Montoya, Oscar Danilo; Giral-Ramírez, Diego Armando (2021-08-28)
Passivity-based nonlinear control for an isolated microgrid system is proposed in this paper. The microgrid consists of a photovoltaic array and a battery energy storage connected to a point of common converters, supplying ...
