A heptagonal photonic crystal fiber-based oil sensor is proposed and numerically investigated in this paper order to detect the adulteration of petrol with kerosene using terahertz (THz) signal. The sensing guiding properties analyzed by Finite Element Method (FEM) technique. achieved a high relative sensitivity 96.87% an extremely low loss 7.21 × 10−4 cm−1 at optimum frequency structural conditions which outstripped other existing researches. In addition, offers small effective material...
In modern power systems, conventional energy production units are being replaced by clean and environmentally friendly renewable resources (RESs). Integrating RESs into systems presents numerous challenges, notably the need for enhanced grid stability reliability. RES-dominated fail to meet sufficient demand due insufficient inertia responses. To address this issue, various virtual emulation techniques proposed bolster system amidst increased integration of sources grid. This review article...
In this work, the optimization of an off-grid micro-hybrid system is evaluated. This conducted with estimation proper sizing each element and steady-state voltage, frequency, power responses microgrid. Kangaroo Island in South Australia considered to be test case location grid incorporates solar PV (photo-voltaic), diesel generator, battery storage, wind turbine. Optimal studied microgrid carried out for four various dispatch techniques: (i) cycle charging (CC), (ii) generator order (GO),...
In this paper, we numerically debrief an ultra-high sensitive surface plasmon resonance (SPR) biosensor utilizing thin layers of graphene oxide (GO) that have not been addressed adequately till now. By the deposition GO on top metal-dielectric heterostructure, our proposed sensor can achieve higher sensitivity and Quality Factor (QF) simultaneously which has possible by existing models to knowledge. Because its large area <italic xmlns:mml="http://www.w3.org/1998/Math/MathML"...

The nuclear reactor plays a key role in power plant (NPP) for electricity generation. Various types of reactors are available around the world, among them VVER-1200 is generation III+ and considered one safest world but as it an electrical system so there must be some possibility faults. Prior knowledge about fault situations needed to take necessary steps withstand situation. In this paper, situation on made by PCTRAN (2006) prototype software. Types were include loss normal feedwater flow,...
This paper represents a series connection of diode-bridge type resonance-based fault current limiter (RLC-BFCL), which elevates the low voltage ride-through (LVRT) capability. Proposed not only limits during symmetrical three line-to-ground faults (3LG) but also protects rotor side converter (RSC) from destroying and regains very quickly. A 3LG is severe for doubly fed induction generator (DFIG). It crucial to enhance transient stability DFIG when this occurs. During standard operation time...
In an isolated microgrid, in the absence of a rotating synchronous machine, virtual generator behaves as machine within converter-based system and mitigates instability issues. This paper presents enhancement to control techniques for inverter-based resources, aiming address concerns. The improvement involves change outer active power loop by incorporating extra inertia support through regulating angle responses while disturbances occur microgrid. To report investigate impact proposed...
Due to the growing electricity concern, it is very much needed use wind power for generation of electricity. But random variation speed, output generator fluctuates randomly as well fluctuation frequency occurs. As a result this decreases energy. This paper represents speed controlled pitch controller control and also reduce fluctuations. For simulation analysis, real data used analysis have been performed by using PSCAD/EMTDC [1].

Transformerless inverters have harmonic distortions present in their output voltage due to power electronics switching. Total Harmonic Distortions the can be minimized by using 5-level Cascaded H-bridge Inverter instead of 3-level or 2-level Inverter. To maintain IEEE Standards, an LCL filter is proposed which used between inverter and load. Simulation two types with without a different kinds switching are done. Comparing result, cascaded combination for having lowest distortion. results...
