The paper has given an overview of different power electronic converters in WTSs with special attention paid to the many possible topologies at low voltage and medium voltage. An important trend is that the technology is moving toward a higher power level. and it is inevitable that it goes for …

This paper has presented a mean shift-based machine vision method for detecting fingerprint and contamination defects in multicrystalline solar wafers. The defect types involve random gradient directions. whereas the normal grain edges generally present more consistent gradient directions in a small spatial window. The entropy of gradient directions is then …

The fault diagnosis of wind converter is in continuous development in recent years. It reduces the downtime and maintenance cost of WECS. and improves the system availability and operational safety. This paper has surveyed typical fault modes of the fragile components in wind converter and has provided a comprehensive review …

We have investigated the impact of TDD on the performance of 1J n+ p GaAs and 2J n+ p InGaP GaAs cells on Si at AM 1.5G spectrum. The analysis indicates that in a 1J GaAs cell on Si with a 2.5-μm-thick GaAs base. an efficiency of greater than 23% …

In this article. our purpose was improving the DFIG stability with tuning of STATCOM control parameters. In order to select the objective function. we proposed a method with the name of integral of time absolute error index or ITAE then optimization process was done by genetic algorithm. Optimization results showed …

The steady state behaviour of an interconnected DFIG based wind farm with STATCOM and SVC is studied and compared for performance evaluation of the two FACTs devices. . A case was developed in which when the load is connected at the point of common coupling there is a voltage dip …

With an increase of global energy demand arising in urban settlements. the key challenges for the urban energy transition include analysis of energy efficiency options and the potential of renewable energy systems within the existing building stock. making cities a key actor in the transition success. In Urban Energy Systems …

Dynamics and Control of Electric Transmission and Microgrids offers a concise and comprehensive review of the most recent developments and research in grid dynamics and control. In addition. the authors present a new style of presentation that highlights the role of transmission and distribution grids that ensure the reliability and …

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 …
