The amount of distributed energy resources (DERs) has increased constantly worldwide. power ratings DERs have become considerably high, as required by the new grid code requirement. To follow and optimize function grid-connected inverters based on DERs, a phase-locked loop (PLL) is essential for detecting phase angle accurately when voltage polluted harmonics imbalance. This paper proposes novel low-pass notch filter PLL (LPN-PLL) control strategy to synchronize with true instead using...
A composite of hierarchical CoNiSe<sub>2</sub> (CNS) microspheres decorated with a CoFe<sub>2</sub>Se<sub>4</sub> (CFS) nanorod-like architecture was successfully synthesized and the assembled symmetric supercapacitor achieves superhigh energy density.
Abstract Carbon nanotubes (CNT) and metal sulfides have attracted considerable attention owing to their outstanding properties multiple application areas, such as electrochemical energy conversion storage. Here we describes a cost-effective facile solution approach the preparation of (PbS, CuS, CoS, NiS) grown directly on CNTs, CNT/PbS, CNT/CuS, CNT/CoS, CNT/NiS flexible electrodes for quantum dot-sensitized solar cells (QDSSCs) supercapacitors (SCs). X-ray photoelectron spectroscopy,...
The development of combined simple metal oxides and binary on a flexible conductor has been needed as novel approach for energy storage sources. Here, we demonstrate versatile strategy towards the synthesis NiZn2O4-NiO nanoflower array (NFA) composite effectively deposited into nickel (Ni) foam storing applications to achieve better electrochemical results. morphology other physical properties as-developed were analyzed, results suggest that NiO nanoparticles have anchored NiZn2O4 nanoleaves...
The natural dye, curcumin, was extracted from Curcuma longa L. using a simple extraction technique. dye then used as sensitizer in dye-sensitized solar cell (DSSC) without further purification, and its characteristics were studied. treated with acetic, nitric hydrochloric acid for stabilization increasing the conversion efficiency. current efficiency 0.60% acetic acid-treated curcumin which double that of acids dyes. short-circuit (Jsc), open-circuit voltage (Voc) fill factor DSSCs made...
We present a comprehensive overview of the development quantum dot-sensitized solar cells (QDSCs), including photoanodes, sensitizers, electrolytes, and counter electrodes, discuss future prospects for highly efficient stable QDSCs.
We have presented a detailed analysis of the phase transition kinetics and binding energy states solution processed methylammonium lead iodide (MAPbI3) thin films prepared at ambient conditions annealed different elevated temperatures. It is processing temperature environmental that predominantly control crystal structure surface morphology MAPbI3 films. The structural transformation from tetragonal to cubic occurs 60 °C with 30 minute annealing time while 10 posses structure. transformed...
The amount of distributed energy resources (DERs) has constantly increased worldwide. As the power ratings DERs have become considerably high, grid code requirements are necessary to secure reliable generation and transmission for public electric network. In order follow codes various countries optimize function grid-connected inverters DERs, a robust phase-locked loop (PLL) is essential extracting phase information accurately, when voltage polluted by harmonics unbalanced. This paper...
