Use of Hydrogen Energy Storage to Stabilize Solar Power Output With an Energy Efficiency Analysis for European Union Member Countries

Energy Science &Engineering, EarlyView.
Photovoltaic solar power production can be stabilized using hydrogen energy storage. Gaseous hydrogen is produced, compressed, stored, and consumed in fuel cells to provide a constant power output. ABSTRACT Seasonal energy storage as compressed hydrogen offers a potential solution to balance the power grid as intermittent renewable energy sources are ...

Optimal Lithium‐Ion Battery—Supercapacitor Energy Storage System Capacity for Off‐Grid Intermittent Renewable Energy Mini‐Grids

Energy Science &Engineering, EarlyView.
Deployment of an aging‐based controller during designing of optimal lithium‐ion battery—supercapacitor (LB‐Sc) hybrid energy storage system (HESS) capacity, in off‐grid IREMGs, improves performance of the LB and reduces its aging rate. Also, annualised cost of the LB‐Sc HESS improves by 33.15% in relation to optimal LB SESS.

Ambiguity‐Aware Receding‐Horizon Optimization of Wind‐Hybrid Energy Storage Systems Using Type‐3 Fuzzy Modeling for Multimarket Participation

Energy Science &Engineering, EarlyView.
A Type‐3 fuzzy ambiguity encoder converts rolling wind, price, reserve‐activation, and confidence features into central estimates and nested uncertainty bounds. These parameters are updated within a receding‐horizon MILP/MIQP that coordinates wind, battery, and supercapacitor capacity across day‐ahead and ancillary‐service markets.

A Comprehensive Review of Fault‐Current Limiter Technologies for Smart and Resilient Power Systems

Energy Science &Engineering, EarlyView.
This review compares superconducting, solid‐state, and hybrid fault‐current limiters (FCLs) for modern alternating current, direct current, and hybrid grids. It shows that optimal FCL selection depends on fault characteristics, network configuration, voltage level, protection coordination, and resilience requirements rather than on a universally ...

Feasibility Study of Green Hydrogen Production From an Onshore Wind Farm in Campania Region, Italy

Energy Science &Engineering, EarlyView.
Estimate the levelized cost of hydrogen (LCOH) and annual hydrogen output under real wind‐farm parameters. Perform the techno‐economic analysis based on the on‐grid configuration. Quantify the sensitivity of LCOH to variations in grid prices. Provide actionable insights for renewable energy producers and Italian policymakers regarding viable business ...

Using SUMO for Test Automation and Demonstration of Digitalized Railway Concepts

SUMO Conference Proceedings
The Train Dispatcher in the Cloud (ZLiC) is a cloud-based approach to digitalize the German Zugleitbetrieb (comparable to American track warrant control). The ZLiC aims to replace the train dispatcher with speech to text, natural-language understanding,

Robust Coordinated Reserve Optimization Method for Electricity–Gas Systems Considering Multi‐Source Coupling and Multiple Uncertainties

Energy Science &Engineering, EarlyView.
This study proposes a two‐stage robust reserve optimization method for coupled electricity–gas systems to mitigate wind–solar fluctuations and transmission‐line contingencies. By coordinating cross‐network reserves and linearizing complex gas flow equations, the approach significantly enhances system security and economic efficiency under multiple ...

The Efficiency Trap of Agentic AI in Human Resource Management

Human Resource Management, EarlyView.
ABSTRACT Agentic AI transforms HRM from data‐driven support to autonomous execution. Organizations deploy these recursive workflows to eliminate human implementation variance, yet we challenge the assumption that such alignment remains optimal. Drawing on Weick's theory of loose coupling, we argue that delegating HR execution to agentic AI creates ...

A decade of decline and regional disparity: Trends and associated factors in use of ritodrine hydrochloride for threatened preterm labor in Japan, a nationwide ecological study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Ritodrine hydrochloride is a commonly used tocolytic agent for threatened preterm labor in Japan, despite its serious adverse events and limited use in many other countries. National obstetric guidelines have shifted toward restricting its use, but the evidence–practice gap remains unclear. The aim of this study is to determine usage
