Abstract The electrically driven large-load-ratio six-legged robot with engineering capability can be widely used in outdoor and planetary exploration. However, due to the particularity of its parallel structure, the eff...

Abstract Mobile machinery energy efficiency and emission pollution are the national and worldwide issues. This paper contributes in solving these problems by applying a speed variable power source. Unfortunately, almost ...

Abstract This article examines the asymmetries and power dynamics within the international monetary and financial system (IMFS), emphasizing its structural and geopolitical interconnections. The Russian invasion of Ukrai...

The increasing adoption of Renewable Energy Sources (RES) is attributed to their sustainability, reduced environmental impact, and reliance on abundant natural resources. Microgrids are becoming more prevalent in existin...

Hybrid energy storage systems have shown promise in enhancing solar panel systems reliability and efficiency. However, managing the power distribution balance with multiple energy storage units remains a challenge. This ...

Stand-alone microgrids (SAMG) often encounter power quality and stability issues due to the volatile green energy sources and loads. So, the reliability of SAMG is comparably lower. To address this problem, battery energ...

Direct-drive wind farms usually trip all wind turbines to ensure power grid security when facing sub/super-synchronous oscillation risks. Tripping the entire wind farm not only seriously damages the production operation ...

Energy consumption has become one of the greatest challenges in the eld of High Performance Computing (HPC). Besides its impact on the environment, energy is a limiting factor for the HPC. Keeping the power consumption...

Abstract In the power operation scenarios, there are problems such as large differences in target scales, small targets susceptible to occlusion, and limited computational resources for edge devices. This leads to insuff...

This paper presents the design and implementation details of a complete noncontact (NC) voltage acquisition system, which allows the measurement of power-line voltage waveforms without galvanic contact. The system is com...
