AN ANALYTICAL MODEL FOR MISMATCH LOSSES IN PV ARRAYS
International Journal of Solar Energy, 1992Variations in the I-V characteristics of photovoltaic modules can lead to significant power loss. This study deals with an analysis of series-string losses. The current parameter of a set of PV modules is considered as a random variable following the Weibull distribution. An analytical expression has been obtained to predict these losses. A preliminary

Bifacial PV System Mismatch Loss Estimation and Parameterization
2019Non-uniform irradiance on the rear-side of bifacial PV systems can cause additional mismatch loss which may not be appropriately captured in PV energy production estimates and software. We have evaluated several rooftop mounted systems over high albedo reflective roofs.

Optimal Mismatched Filter Design with a Controllable Maximum Loss
OCEANS 2018 MTS/IEEE Charleston, 2018To suppress the masking effect of weak targets due to the range sidelobes of stronger targets, the commonly used mismatched filter is introduced. In this paper, we propose a novel optimal design of mismatched filters with a controllable maximum loss. The optimization problems to minimize the integrated sidelobe level (ISL) or the peak sidelobe level ...

Mismatch repair protein loss and microsatellite instability in cholangiocarcinoma.
Journal of Clinical Oncology, 2014237 Background: Hereditary nonpolyposis colorectal cancer (HNPCC), or Lynch Syndrome, is an autosomal dominant syndrome characterized by mutations in genes involved in DNA mismatch repair (MMR) and consequent microsatellite instability (MSI). These genetic aberrations lead to an increased incidence of multiple malignancies including colorectal and ...

Forecasting photovoltaic array power production subject to mismatch losses
Solar Energy, 2010The development of photovoltaic (PV) energy throughout the world this last decade has brought to light the presence of module mismatch losses in most PV applications. Such power losses, mainly occasioned by partial shading of arrays and differences in PV modules, can be reduced by changing module interconnections of a solar array. This paper presents a

Analysis Model of Mismatch Power Losses in PV Systems
Journal of Solar Energy Engineering, 2009A novel procedure to extract and analyze the power losses, mainly due to mismatch effects, in a photovoltaic (PV) system is presented. The developed model allows the extraction of the main PV module and PV array parameters from I-V characteristics, as well as in dynamic behavior under real conditions of work.

Simplified technique for calculating mismatch loss in mass production
Solar Energy Materials and Solar Cells, 2015Abstract This paper describes a generalised approach to estimating mismatch loss for series connected cells, utilising the result that the deviation from maximum power as a function of deviation from maximum power–point–current is a relatively stable relationship for a wide range of cell performances.

Intrinsic Insertion Loss of a Mismatched Microwave Network
IEEE Transactions on Microwave Theory and Techniques, 1955A brief review is presented of the absolute minimum loss of a two-port, mismatched lossy microwave network. This minimum loss, called the "intrinsic insertion loss" can be attained by adding suitable susceptances at the ports that will yield simultaneous bilateral network match. A measurement procedure is described and convenient graphs are presented.

Raman and Brillouin couplers with losses and phase mismatch
Journal of Modern Optics, 1999We investigate nonlinear couplers whose operation is based on Raman or Brillouin scattering. A quantum approach is used. Strong coherent laser pumping is assumed and linearized Heisenberg-Langevin equations of motion are solved. The influence of linear coupling constants, losses and phase mismatches on the dynamical behaviour of the coupler is ...
