Energy Flows Balance of Electric‐Heating Interconnected Microgrids Under Grid‐Forming Converter Integration Based on Heterogeneous Graph Convolutional Network

Energy Internet, EarlyView.
ABSTRACT The combination of electric‐heating interconnected microgrids (EHIMs) with grid‐forming converters (GFMCs) offers a highly promising approach to improving energy management within decentralised energy systems. Despite its potential, precisely modelling and analysing energy flow in such systems remains a considerable challenge due to the ...

Practical Day‐Ahead Gas Generator Dispatch Optimisation for Enhancing the Reserved Capacity

IET Smart Energy Systems, EarlyView.
Practical day‐ahead gas generator dispatch optimisation model is proposed to enhance the system reserved capacity. ABSTRACT In order to reduce carbon dioxide emissions, traditional coal‐fired power generation has been strictly limited in China recently, which has led to the problem of reserved capacity shortage. As one of the critical east provinces of

Benefit Mechanism and Enhancement Strategy of High‐Proportion Building Photovoltaic Systems Under Carbon Reduction Constraints

IET Smart Energy Systems, EarlyView.
A benefit evaluation framework for high‐proportion building photovoltaic systems was established considering carbon reduction constraints and grid absorption costs. The study reveals the intrinsic contradiction between system‐level benefits and PV utilisation benefits, and proposes a dual‐driven optimisation pathway of effective generation and ...

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.
