Applying conservative power theory for analyzing three-phase X-ray machine impact on distribution systems
(2015-12-28)
This article proposes the use of the conservative power theory as an alternative tool to analyze and determine the possible impacts of noisy loads on electrical distribution systems. The orthogonal decomposition of current ...
Main maximum power point tracking strategies intended for photovoltaics
(2011-12-28)
This paper presents evaluations among the most usual MPPT techniques, doing meaningful comparisons with respect to the amount of energy extracted from the photovoltaic panel (PV) (Tracking Factor - TF) in relation to the ...
An Efficient Forecasting-Optimization Scheme for the Intraday Unit Commitment Process Under Significant Wind and Solar Power
(2018)
Due to their uncertain and variable nature, the large-scale integration of wind and solar power poses significant challenges to the generator scheduling process in power systems. To support this process, system operators ...
