An Efficient Hybrid Islanding Detection Method for Microgrids Using Kalman Filter

Engineering Reports, Volume 7, Issue 12, December 2025.
Islanding condition gives rise to several problems in distributed generation networks, including power quality disturbances, equipment damage, interference with grid protection, and danger to the utility crews. To avoid islanding detection failure of the passive section in case of a close matching between islanded generation units and loads, the active

An Energetically and Observationally Constrained Mesoscale Parameterization for Ocean Climate Models

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 12, December 2025.
Abstract An extension of the GEOMETRIC parameterization (Mak, Marshall, et al., 2022, https://doi.org/10.1029/2022ms003223) for the mesoscale eddy transport is proposed and tested in a one‐degree resolution global ocean model. It consists in solving a prognostic two‐dimensional equation for the eddy kinetic energy (EKE). The parameterized EKE budget is

Optimal control of single‐phase microgrid with photovoltaic and energy storage for improving operation performance and seamless state transition

Energy Conversion and Economics, Volume 6, Issue 5, Page 324-340, October 2025.
Abstract Under voltage sags, swells, stochastic load profiles and harmonic voltage distortion, conventional synchronisation mechanisms often fail to track the grid voltage immediately and accurately, leading to degraded control performance and potential power quality violations.

Born to Fear the Machine? Genetic and Environmental Influences on Negative Attitudes toward AI Agents

Advanced Science, Volume 12, Issue 35, September 18, 2025.
Why do some people fear or distrust AI agents more than others? This twin study shows that negative attitudes toward AI may partly stem from genetic factors, linking them to traits like victim sensitivity and moral beliefs. These findings show that it is not only nurture but also nature that shapes our views of AI, with implications for future human–AI

Active Anti-Islanding technique with reduced Non-Detection Zone for Centralized Inverters

, 2018
This paper presents an active anti-islanding scheme for grid-tied centralized inverters for large Photovoltaic (PV) power plants. The proposed technique involves appropriate reactive power injection into the grid which results in the positive/negative ...

Genetic and Environmental Contributions to Child Height in Low‐ and Middle‐Income Countries

American Journal of Human Biology, Volume 37, Issue 9, September 2025.
ABSTRACT Background Child height is influenced by genetic and environmental factors. However, it is unclear how these factors vary by geographical region and by study design, particularly in low‐ and middle‐income countries (LMIC), where data is scarce.

Improved Theoretical Estimates of the Zonal Propagation of Global Nonlinear Mesoscale Eddies

Journal of Geophysical Research: Oceans, Volume 130, Issue 6, June 2025.
Abstract Mesoscale eddies are essential for transport and mixing processes in the global ocean, with their characteristic westward propagation being a significant finding from the satellite altimetry era. Traditional predictions of their zonal propagation rely on the theoretical phase speed of long baroclinic Rossby waves; however, this approach is ...

Modified Q–f Droop Curve Method for Islanding Detection With Zero Non-Detection Zone

IEEE Access, 2021
In this paper, a modified Q-f droop curve method for the inverter-based distributed generator is proposed. The proposed method has merits such as detecting islanding with zero non-detection zone, negligible effects on power quality, and simple ...
