In the present scenario depletion of conventional sources causes an energy crisis. The crisis load demand with respect to electricity. use renewable plays a vital role in reducing and reduction CO2 emission. solar is major source power generation as this root cause for development wind, tides, etc. However, due climatic condition availability PV varies from time time. Hence it essential track m...
In this paper, an arti cial neural network based-model (ANNBM) is introduced for partial shading detection losses in photovoltaic (PV) panel. A Multilayer Perceptron (MLP) is used to estimate the electrical outputs (current and voltage) of the photovoltaic module using the external meteorological data : solar irradiation G (W/m2) and the module temperature T (μrC). Firstly, a database of the BP...
This paper compares two common risk-modeling approaches and then uses them to analyze the risk of incorporating solar photovoltaic (PV) systems into a commercial electric power grid. It uses procedures from both approaches such as Hierarchical Holographic Models, frequency and severity normalization, and avoiding numerical skewing by rare but serious events: It describes the benefits and limita...
The Z-source inverter (ZSI) with battery operation can balance the stochastic fluctuations of photovoltaic (PV) power injected to the grid/load, but the existing topology has a power limitation due to the wide range of discontinuous conduction mode during battery discharge. This paper proposes a new topology of the energy stored ZSI to overcome this disadvantage. Two strategies are proposed wit...
Microgeneration using solar photovoltaic (PV) systems is one of the fastest growing applications of solar energy in the United States. Its success has been partly fueled by the availability of net metering by electric utilities. However, with increasing solar PV penetration, the availability of net metering is likely to be capped. Households would then need to rely on distributed storage to cap...
Coxiella burnetii is the etiologic agent of human Q fever and targets alveolar phagocytic cells in vivo wherein the pathogen generates a phagolysosome-like parasitophorous vacuole (PV) for replication. C. burnetii displays a prolonged growth cycle, making PV maintenance critical for bacterial survival. Previous studies showed that C. burnetii mediates activation of eukaryotic kinases to inhibit...
Due to ready availability of resources, there is a vast spike in the growth of sustainable power sources. Among them solar photovoltaic (PV) world power technique is presently careful, being an of great magnitude substitute influence supplier, for the reason that of the set availability of eminent able PV panels with the aim of eliminate the depressing environmental aspects. Low voltage PV syst...
For over 30 years, HIV/AIDS has wreaked havoc in the world. In the absence of an effective vaccine for HIV, development of new anti-HIV agents is urgently needed. We previously identified the antiviral activities of the scorpion-venom-peptide-derived mucroporin-M1 for three RNA viruses (measles viruses, SARS-CoV, and H5N1). In this investigation, a panel of scorpion venom peptides and their der...
Accurately determining photovoltaic (PV) module performance in the field requires measuring solar irradiance reaching the PV panel at a high level of accuracy and known uncertainty. Silicon detectors used in various solar energy measuring instruments that include reference cells are a potentially attractive choice for multiple reasons, including faster responsivity than thermopile detectors, ch...
We formulate, solve computationally and study experimentally the problem of collecting solar energy in three dimensions. We demonstrate that absorbers and reflectors can be combined in the absence of sun tracking to build three-dimensional photovoltaic (3DPV) structures that can generate measured energy densities (energy per base area, kWh/m) higher by a factor of 2–20 than stationary flat PV p...
