Based on silver nanoparticle arrays and blazed grating arrays. we have designed structures of thin film silicon solar cells both at the front and the rear surfaces. In the design of the front surface of the cells. silver nanoparticle arrays have been placed in order to increase the light transmittance …

In this paper. a comprehensive electrical modeling of PV has been carried out and a generalized PV simulator has been proposed and designed in MATLAB Simulink software package. The proposed simulator has been developed as a masked block. It can simulate any number of panels connected in series and parallel. …

It'.s a form of transportation uses magnetic levitation to float vehicles above a track.

This fully updated electrical safety guide is a practical. illustrated source of life-saving information designed for specific work environments. The book has been fully revised and expanded to conform to every current major electrical standard. including NEC. NESC. NFPA70E. IEEE 1584. and OSHA.    Written by experts in electrical operations. …

This paper has presented a novel control of an existing gridinterfacing inverter to improve the quality of power at PCC for a 3-phase 4-wire DG system. It has been shown that the grid-interfacing inverter can be effectively utilized for power conditioning without affecting its normal operation of real power transfer. …

Fixed speed and variable speed wind generator models for power system dynamics and transient stability analysis were presented. The models are valid for the simulation of system faults and power fluctuations resulting from wind-turbulence. For estimating wind-turbulence in wind farms a stochastic turbulence model was presented considering rotational sampling. tower …

In this work. the most widely used MPPT algorithms have been modeled and evaluated according to simulations in Matlab Simulink environment based on the dynamic response of the PV system. the tracking speed of convergence. the efficiency and the ease of implementation. The results indicate that the modified fractional OC …
