Investigating the performance of non‐standard characteristics‐based overcurrent relays and their optimum coordination in distributed generators connected networks

open access: yesIET Generation, Transmission & Distribution, 2023
To handle the challenges attributed to the distributed generators, the protection system of distribution networks needs to be evolved. Recent protection schemes modify the standard characteristics of overcurrent relays, called non‐standard ...

V2G Scaling for Electric Trucks From a Cyber‐Physical‐Social Perspective: Challenges and Pathways

open access: yesEnergy Internet, EarlyView.
ABSTRACT Under the dual carbon strategy, electric trucks, as a key element in emission reduction within the transportation sector, can achieve a mutually beneficial situation for both the power system and the transportation system through vehicle‐to‐grid (V2G).

Enhancing the protection of photovoltaic-based DC microgrids using circuit breaker operation sequence

open access: yesInternational Journal of Electrical Power & Energy Systems
The advancement of direct current (DC) microgrids is limited by insufficient operational experience, the inadequacy of suitable protective devices, and the absence of effective fault analysis methods.

Influence of Inverter-Based Resources on Microgrid Protection: Part 2: Secondary Networks and Microgrid Protection

open access: yesIEEE Power and Energy Magazine, 2021
Secondary networks are deployed when exceptionally high-reliability electric service is required for specific loads. Secondary network protection makes extensive use of the fact that the available fault currents in such systems are typically very high ...

GOVERNING THE CLOUD: Infrastructural Statecraft and the Political Ecology of Digital Expansion in Oregon

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract Oregon's wave of data center and semiconductor projects shows how cloud capitalism reorganizes resource systems and territorial governance. Examining Amazon, Google, and Intel, the article traces how fiscal incentives, utility programs, and land‐use instruments are recalibrated to secure hyperscale loads.

Performance Evaluation of Fuel Cell and Microturbine as Distributed Generators in a Microgrid [PDF]

open access: yes, 2009
This paper presents dynamic models of distributed generators (DG) and investigates dynamic behaviour of the DG units within a microgrid system. The DG units include micro turbine, fuel cell and the electronically interfaced sources.

Dilemmas of Civilian Participation in Military Deterrence and Defence: Legal and Ethical Dimensions

open access: yesGlobal Policy, EarlyView.
ABSTRACT How can civilians participate in deterrence and defence in ways that do not jeopardize their immunity from deliberate attack? The principle of civilian immunity from deliberate attack in war is a core element of contemporary international humanitarian law (IHL). Uniformed combatants and others who take up arms pose a threat may be liable to be

Flexibility-based anti-islanding protection of a microgrid integrated with power grid

open access: yes, 2017
The widespread adoption of Renewable Energy Resources (RER) and Plug-in Electric Vehicles (PEVs) in distribution systems has achieved a substantial energy share, allowing the microgrid to participate in the open market.

Beyond Risk Reduction: Leveraging Multiple Resilience Dividend Concept for Transformative Adaptation Planning

open access: yesClimate Resilience and Sustainability, Volume 5, Issue 2, December 2026.
This paper presents a framework for Multiple Resilience Dividends (MRD) that proposes shift climate change adaptation from a narrow risk‐focused perspective to a broader, multi‐objective systems approach. By recognizing the diverse range of benefits that adaptation measures can provide, practitioners can go beyond merely avoiding losses.
