The GSC control algorithm of the proposed DFIG has been modified for supplying the harmonics and reactive power of the local loads. In this proposed DFIG. the reactive power for the induction machine has been supplied from the RSC and the load reactive power has been supplied from the GSC. …

In this paper a new topology for wind turbines based on doubly-fed induction generator was proposed. The idea behind that work is use the FACTS features of the WT-DFIG to improve the power quality into the point of common coupling (PCC). Besides the inherent advantages to the active filters. through …

The present study provides a systematic approach to derive a large collection of methods to determine the series resistance of a solar cell. Representation of the methods in the two-dimensional array presented in Table 1 allows for easy comparison and reveals that many previously published methods are more alike than …

This paper investigates the role of reactive power compensator STATCOM and presents a control system based on simultaneous control of STATCOM reactive power and pitch angle of rotor blades for improving stability margin of speed of induction generator. As it can be seen in Fig. 12. critical clearing time i.e. …

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 …
