Redefining Decoupled Water Electrolysis as an Integrated Hydrogen‐Carrier Platform

Advanced Energy Materials, EarlyView.
This Perspective focuses on transportable solution‐phase proton‐coupled mediators and evaluates them using carrier‐level capacity, retention, energy, release, pressure, purity, and closed‐loop logistics boundaries; solid and device‐bound systems are shown as explicit boundary cases.

An Overview and Minimum Fault Ramp Rate Analysis of Impedance Based Circuit Breaker Topologies

IEEE Access, 2023
In the advent of recent developments in a higher efficiency Direct Current (DC) system, the DC microgrid proves to be a permissible future to match the load demand with distributed power generation.

A Paradox Perspective on Business Model Innovation in Sustainability‐Oriented Industries: A Longitudinal Case Study in the Energy Sector

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines how Business Model Innovation (BMI) unfolds in sustainability‐oriented industries, where institutional complexity, technological interdependence, and environmental imperatives generate persistent sustainability‐related paradoxical tensions.

Enhancing Microgrid Protection Through Adaptive Decentralized Relay Coordination: A Solution to Blinding and Sympathetic Tripping

IEEE Access
Integrating Distributed Energy Resources into microgrids modifies the network’s system parameters and causes it to exhibit behaviour, particularly during fault conditions.

An Active Protection Scheme for Islanded Microgrids [PDF]

15th International Conference on Developments in Power System Protection (DPSP 2020), 2020
The paper proposes a relatively simple active protection strategy incorporating controllers of the inverter for islanded microgrids dominated by inverter based distributed generators (IBDGs) that can overcome well-understood shortcomings in traditional overcurrent protection schemes applied to weak islanded systems.

Transition Metal Compounds as Thermochromic Materials: Classification, Properties, Limitations, and Applications

EcoEnergy, EarlyView.
This review systematically examines how different transition metal compounds—such as binary and multinary metal oxides, halides, sulfides, and salts—exhibit thermochromism based on the d‐electron configurations of their transition metal cations. It focuses on three main mechanisms of thermochromism: phase transition, charge transfer, and bandgap change.

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.

Design of Microgrid Protection Schemes Using PSCAD/EMTDC and ETAP Programs

Energies, 2020
Steady-state, harmonics, and transient analysis of a power system by using a detailed simulation model is essential to microgrid operation before the installation of new power facilities, because the microgrid, which is a small-scale independent power ...

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 ...
