Advances in Triboelectric Nanogenerators With Rotating Structure

Carbon Energy, Volume 8, Issue 2, February 2026.
The rotating TENG has been widely studied for its superiorities of simple structure, high efficiency, and stable output. This review introduced the four different principles of rotating TENG and offered a thorough summary for performance and application research through three‐level classification. Importantly, the current existing problems, challenges,

Behavior of HAWT with Differential Planetary Gearbox

Journal of Power and Energy Engineering, 2014
A dynamic model for simulating behavior of a horizontal axis wind turbine (HAWT) with differential planetary gearbox is developed. The aerodynamic load applied to the wind turbine connected with the carrier is described using the quasi-steady approach. The control torque is assumed to be applied to the external ring of the gearbox.

Improving the Characteristics of the Direct FOC Strategy in DFIG‐Based Wind Turbine Systems Using FOIDD and FOPD Controllers

Energy Science &Engineering, Volume 14, Issue 2, Page 999-1021, February 2026.
This study presents a new control strategy for doubly fed induction generator (DFIG) wind turbine systems to overcome the limitations of traditional direct field control using proportional‐integral (DFOC‐PI) regulators, which are sensitive to coefficient changes and lead to low power quality.

Conceptual design of planetary gearbox system for constant generator speed in hydro power plant

MATEC Web of Conferences, 2018
Micro Hydro Power Plant (MHPP) is emerging as one of the most clean, renewable and reliable energy technology for harnessing power. In MHPP hydro governors are avoided, that results in turbine speed fluctuation.

Experimental Analysis and Physics‐Based Analytical Model on Twisted and Coiled Artificial Muscles

Advanced Engineering Materials, Volume 28, Issue 2, 21 January 2026.
Twisted and coiled artificial muscles made from silver‐coated nylon fibers are investigated through experiments and analytical modeling. The actuators achieve contractions up to 19.3% and specific work of 8 kJ kg−1, though efficiency remains limited (≈0.15%) by thermal losses.

Sustainable Energy Management in Islanded Microgrids via HHO–BE Tuned Adaptive Controllers and Demand‐Side Flexibility

Engineering Reports, Volume 8, Issue 1, January 2026.
This research presents a novel approach to frequency control in isolated hybrid microgrids by developing an adaptive fractional‐order PI controller. The controller is optimized using the Harris Hawks Optimization algorithm, enhanced with the Balloon Effect (HHO + BE), to ensure high precision and adaptability.

Intelligent Fault Diagnosis for Laboratory Equipment

Electronics Letters, Volume 62, Issue 1, January/December 2026.
ABSTRACT Traditional laboratory management relies heavily on manual oversight and static threshold‐based fault diagnostics, which are inadequate for addressing the dynamic, individualised needs of contemporary environments. To address these challenges, we proposed an intelligent laboratory management framework, designed to enable secure and autonomous ...
