Power flow solution in direct current grids using the linear conjugate gradient approach
(2019-09-24)
The Colombian power system is being modified by the large-scale integration of renewable energy resources and energy storage systems, in conjunction with the microgrid concept that originates the possibility of alternating ...
Voice compression using discrete cosine transform and wavelet transform
(Institute of Physics Publishing, 2019)
Compressing information, such as voice, allows freeing up memory space, better utilizing bandwidth, in other words taking advantage of resources more efficiently in a time where technologies such as Voice over Internet ...
Voltage stability margin in DC grids with CPLs: A recursive Newton-raphson approximation
(2019-03-11)
This express brief addresses the voltage collapse problem in direct-current (dc) networks by using a recursive heuristic search algorithm based on the Newton-Raphson method. The determinant of the Jacobian matrix in the ...
Optimal power flow in direct-current power grids via black hole optimization
(VSB-Technical University of Ostrava, 2019)
This paper addresses the Optimal Power Flow (OPF) problem in DC power microgrids via a combinatorial optimization technique known as Black Hole Optimization (BHO). Such optimization method allows to solve OPF problems via ...
Power quality detection and classification using wavelet and support vector machine
(2019-09-24)
This work presents the identification and classification of various disturbances that affect the quality of energy, seen as the quality of the voltage wave (harmonics, sag, swell and flicker). For this, the wavelet transform ...
