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 …

The new formulation for the electrical modeling of the three-level converter combined with the new control strategy reveals the capability in mitigating the unbalancing between the capacitors bank voltages. The THD of the output current with the two-level converter and with the three-level converter have propensity to be decremented with …

Application of Smart Grid Technologies: Case Studies in Saving Electricity in Different Parts of the World provides a wide international view of smart grid technologies and their implementation in all regions of the globe. A brief overview of smart grid concepts and state-of-the art technologies is followed by sections that …

The creation of a flexible. efficient. digitized. dependable and resilient power grid may well be the best route to increasing energy efficiency &amp. security. as well as boosting the potential of renewable &amp. distributed power sources. This book covers smart grids from A-Z. providing a complete treatment of the topic. …

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. …

This paper presents Genetic Algorithm based reconfiguration scheme for the arrangement of PV modules in a PV array which exhibits increased array power generation under partially shaded conditions. The reconfiguration technique involves changes in the electrical interconnections for shade dispersion keeping the physical location of the PV modules unchanged. The …

In this paper. a modeling method based on the genetic algorithm is proposed. The values of the PV module parameters were computed in such a way that the error between the simulation results and the data sheet information is minimized. A global optimization for the values of the parameters was …

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 …
