Improved genetic algorithm for phase-balancing in three-phase distribution networks: A master-slave optimization approach
(2021-05-14)
This paper addresses the phase-balancing problem in three-phase power grids with the
radial configuration from the perspective of master–slave optimization. The master stage corresponds
to an improved version of the Chu ...
A mixed-integer nonlinear programming model for optimal reconfiguration of DC distribution feeders
(2020-08-27)
This paper deals with the optimal reconfiguration problem of DC distribution networks by proposing a new mixed-integer nonlinear programming (MINLP) formulation. This MINLP model focuses on minimising the power losses in ...
A Comparative Study on Power Flow Methods Applied to AC Distribution Networks with Single-Phase Representation
(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) ...
LQR-Based adaptive virtual inertia for grid integration of wind energy conversion system based on synchronverter model
(2021-03-06)
This paper proposes adaptive virtual inertia for the synchronverter model implemented in a wind turbine generator system integrated into the grid through a back-to-back converter. A linear dynamic system is developed for ...
Sensorless Adaptive Voltage Control for Classical DC-DC Converters Feeding Unknown Loads: A Generalized PI Passivity-Based Approach
(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 ...
Direct Power Control Design for Charging Electric Vehicles: A Passivity-Based Control Approach
(2020-11-25)
This paper explores the controller's design for charging batteries for electric vehicle applications using the direct power representation of the system. These controllers' design is made via passivity-based control (PBC) ...

Hybrid calibration method for improving 3D measurement accuracy of structured light systems
(2020-08-21)
In structured-light systems, the lens distortions of the camera and the projector reduce the measurement accuracy when calibrated as a standard stereo-vision system. The conventional compensation via distortion coefficients ...
A low-cost multi-modal medical imaging system with fringe projection profilometry and 3D freehand ultrasound
(2020-01-03)
The growing need to perform surgical procedures, monitoring, and intervention of greater precision have led to the development of multimodal medical imaging systems. Multimodal images are a strategy to overcome the limitations ...
Automated corneal endothelium image segmentation in the presence of cornea guttata via convolutional neural networks
(2020-08)
Automated cell counting in in-vivo specular microscopy images is challenging, especially in situations where single-cell segmentation methods fail due to pathological conditions. This work aims to obtain reliable cell ...
