The objective of this thesis is the development of control strategies for distributed generation systems during voltage sags. The proposed control strategies present different options to improve the ...
Guzmán Solà, Ramon (Date of defense: 2016-10-14)
The present thesis is focused on the control of three-phase power converters using sliding-mode control (SMC) in abc frame. This work has been based on previous publications about the SMC applied to ...
Barrenechea Gruber, Roberto Carlos (Date of defense: 2019-01-11)
In this work, a new algorithm for the multiobjective optimization of low and medium voltage electrical grids and microgrids is proposed. The originally nonlinear planning model is linearized using the ...
Lamich Arocas, Manuel (Date of defense: 2015-02-27)
The increasing use of DC electronic devices connected to mains lead to numerous complications of harmonic distortion and efficiency reduction in electrical energy transmission. These devices behave as ...
