Decentralisation of power generation is generally acknowledged one of characteristics of future smart grids. Different conventional and renewable energy sources will be installed in different locations but supporting the common grid network. The energy sources will work separately but with communication to optimize the power flow in the grids. Currently, solar energy is the most commonly used a...

Green roof and solar photovoltaic (PV) systems are two technologies that could contribute to sustainable building development and reduction of greenhouse gas emissions. When they are combined together on the building roof, it can enhance their functions and effectiveness by cooling and shading effects. This paper explains the major findings of a research to study the benefits of integrating gre...

Climate change experiments run on Intergovernmental Panel on Climate Change (IPCC)–class numerical models consistently suggest that increasing concentrations of greenhouse gases will lead to a poleward shift of the midlatitude jets and their associated eddy fluxes of heat and potential vorticity (PV). Experiments run on idealized models suggest that the poleward contraction of the jets can be t...

The proposed photovoltaic Micro Inverter is based on three port flyback with one port dedicated to power decoupling function so the decoupling capacitance is reduced and hence the long lifetime film capacitor is used. One of the two transformers and one capacitor is used for decoupling function. The decoupling capacitor functions as energy storage as well as snubber capacitor to recycle the tra...

The majority of cortical interneurons use GABA (gamma amino butyric acid) as inhibitory neurotransmitter. GABAergic neurons are morphologically, connectionally, electrically and chemically heterogeneous. In rat cerebral cortex three distinct groups of GABAergic interneurons have been identified by the expression of parvalbumin (PV), calretinin (CR) and somatostatin (SOM). Recent studies in mous...

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract –This paper proposes the controlling of the photovoltaic (PV) system by sliding mode control(SMC). Here, open circuit voltage MPPT technique is used to track maximum power point. There is a difficulty in tracking the maximum power point of the phot...

Photovoltaic(PV) systems are expected to play an important role in future energy production. An asymmetrical interleaved high step-up converter is used to get high step up gain to step up the input energy which is obtained from PV panel without operating at an extreme duty ratio. The traditional inverter which is used to convert the converter output energy from DC to AC, contains a line frequen...

The ability to accurately characterize a Photovoltaic (PV) product is critical at every level of system development. The characterization of systems and devices allows research teams and product development groups to not only map the progress of their own technology but also compare it to that of their competitors. Access to state of the art testing equipment thus allows these teams to make eff...
