A large part of photovoltaic research is dedicated to developing innovative integration technology for the module. Now the use of a storage function in such intermittent power supply systems is crucial in order to get better adequacy between the peaks of energetic consumption and production. The integration degree of photovoltaic …

In this paper. reactive power injection strategies for singlephase PV systems considering grid requirements have been explored. The proposed reactive power injection strategies include constant average active power control. constant active current control. constant peak current control. and thermal optimized reactive power control strategy. which is dedicated to improve the …

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 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 …

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. …
