Distance protection for microgrids in distribution system [PDF]

IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015
Owing to the increasing penetration of distributed generation, there are some challenges for the conventional protection in distribution system. Bidirectional power flow and variable fault current because of the various operation modes may lead to the selectivity and sensitivity of the overcurrent protection decreased.

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

IET 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 ...

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

International 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.

SMAA‐Based FITradeoff: An Efficient Framework for Pairwise Elicitation in Multicriteria Decision Analysis

Journal of Multi-Criteria Decision Analysis, Volume 33, Issue 2, August 2026.
ABSTRACT The Flexible and Interactive Tradeoff Elicitation (FITradeoff) method is a Multi‐Attribute Decision‐Making (MADM) approach designed to capture the preferences of a Decision Maker (DM) while minimising cognitive effort. To reduce the frequency of interactions and optimise the preference elicitation process, this paper introduces an innovative ...

Circular Economy Pathways for Airport Climate Change Mitigation

Business Strategy and the Environment, Volume 35, Issue 5, Page 7378-7397, July 2026.
ABSTRACT Airport operators face growing climate‐change pressures; the circular economy offers pathways to reduce impacts and recover resources. We examine how airport operators apply the circular economy in practice. We use an exploratory qualitative multicase design based on practitioner‐generated documents (e.g., press releases and sustainability ...

Optimal Control of Mobile Energy Storage via Knowledge‐Guided Deep Reinforcement Learning

Battery Energy, Volume 5, Issue 4, July 2026.
This research proposes a Knowledge‐Guided DRL framework (KA‐DDPG) for mobile energy storage. By integrating offline optimization as expert guidance to manage hybrid action spaces and environmental uncertainties, our method achieves significantly higher arbitrage profits and superior operational stability compared to standard reinforcement learning and ...

Microgrid Protection

, 2020
Designing an overall protection system for the installation of a microgrid is a major technological problem. For both grid-connected and islanded operation, the general specification like sensitivity, reliability, and selectivity must be met by the protection system.

ELECTRICAL PROTECTION OF MICROGRIDS

EMERG - Energy. Environment. Efficiency. Resources. Globalization
The present work originates from the necessity of evaluating the electrical supply scheme of a bus charging station. Based on this framework, a microgrid model interconnected with the public network was developed, within which the calculations and dimensioning of short-circuit currents and transformer operating voltages were carried out.
