Improvements in closed-section wind-tunnel beamforming experiments of acoustic sources distributed along a line
(2019-12-15)
Phased-array microphone techniques are widely used tools for the measurement and analysis of aeroacoustic noise sources. Nevertheless, beamforming results of sources distributed along a line, such as airfoil trailing-edge ...
Simulation of photovoltaic centrals with dynamic shading
(Elsevier, 2013-03)
The increase in the power of photovoltaic systems involves a significant grow in the number of modules that make them up. The known problems caused by the shading are not usually taken into account in the design of a ...
MPPT of a Photovoltaic Panels Array with Partial Shading Using the IPSM with Implementation Both in Simulation as in Hardware
This article presents a method for the Maximum Power Point Tracking (MPPT) of a Photovoltaic (PV) panels array with partial shading, applying an Improved Pattern Search Method (IPSM). The method is simulated in PSIM @ and ...
Estimating the produced power by photovoltaic installations in shaded environments
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2015-07-01)
A model to improve the estimation of the power and energy from photovoltaic installations under dynamic shading conditions is proposed in this paper. The model considers the shaded profile in each photovoltaic module and ...
Análise e projeto de conversores estáticos para sistemas fotovoltaicos parcialmente sombreados
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2016-08-29)
This work presents a study and analysis of photovoltaic systems subject to partial

Deep reinforcement learning approach for MPPT control of partially shaded PV systems in Smart Grids
(Elsevier Science, 2020-12)
Photovoltaic systems (PV) are having an increased importance in modern smart grids systems. Usually, in order to maximize the energy output of the PV arrays a maximum power point tracking (MPPT) algorithm is used. However, ...
Reconnection patterns of photovoltaic cells to reduce power loss due to detrimental conditions
(Universidade Federal de Minas GeraisUFMG, 2017-11-13)
Defective or under illuminated photovoltaic (PV) cells on an array affect the performanceof the whole panel. In this work, the best connection design among cells is investigated for various shading situations. It is assumed ...
