Applicability of Droop Regulation Technique in Microgrid - A Survey

Currently, the worth of power generation on the basis of renewable sources is rapidly growing. Correspondingly the microgrids and the DG units are impressed the researchers for their peculiar features. Power sharing is the major concern when various DGs are connected to the microgrid via power electronic converters. It is mandatory to achieve an appropriate power sharing when the manifold DGs are activated in parallel. For that, the two ultimate quantities - power angle δ and voltage magnitude V are regulated to acquire the real and reactive power sharing correspondingly. Many innovative control techniques have been used for load sharing. The most common method of local load sharing is the droop characteristics. Subsequently, there is a swift momentum in the advancement of researchers to meet the challenges of the droop control techniques in the power sharing concerns, an extensive literature review on active and reactive power sharing, voltage and frequency control in microgrid has been emphasized. The various conventional and modified droop control techniques/strategies that relates to power sharing issues have been highlighted in this work

Performance Analysis of Autonomous Microgrid Subsequent to Symmetrical and Unsymmetrical Fault Triggered Condition

Hi-tech scenario and the ecological compression are the key point to drive the intervention of the renewable in the distribution system. In the perspective of complex power system planners, the transient performance of the microgrid is the main concern. For that purpose, various fault cases are explored in order to examine the microgrid transient performance when subjected to accidental events. In this work, the microgrid is modelled with two distributed generations (DGs) tied with a converter separately. With this intention, droop control strategy is adopted for the microsources to examine the microgrid performance during the symmetrical and unsymmetrical fault events. The ability of the control strategy adopted in this work and its effectiveness are evaluated through Matlab/Simulink platform

Green Synthesised Silver Nanoparticles Using <i>Anoectochilus elatus</i> Leaf Extract: Characterisation and Evaluation of Antioxidant, Anti-Inflammatory, Antidiabetic, and Antimicrobial Activities

The present study investigates the green synthesis of silver nanoparticles was carried out using a leaf extract of Anoectochilus elatus (Ae-AgNPs). The synthesised Ae-AgNPs were characterised using different analytical techniques like UV-visible spectroscopy, X-ray diffraction (XRD), Fourier transform infrared (FTIR), and scanning electron microscopy (SEM) with energy-dispersive X-ray analysis (EDX). Additionally, in vitro activities were investigated, and they possess antioxidant, anti-inflammatory, antidiabetic, and antimicrobial properties. The UV-Vis spectra exhibited characteristic absorption peaks at approximately 480 nm. FTIR identified functional groups of the Ae-AgNPs. The crystalline structure of the Ae-AgNPs was verified via XRD analysis. SEM studies revealed that the nanoparticles exhibited a spherical morphology. The fabrication of Ae-AgNPs was established by the EDX spectrum, which exhibited prominent signals of silver atoms. The Ae-AgNPs show potent antioxidant, anti-inflammatory, and antidiabetic activity compared to standard drugs. In addition, Ae-AgNPs demonstrated the most significant zone of Inhibition. This study affirms the superior biological capability of Ae-AgNPs for target drug delivery and their potential for usage in biomedical research and therapeutics
