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 ...

Research Progress on Electrical Insulation Under Superimposed Voltage With High‐Frequency Harmonics in New‐Type Power Systems

High Voltage, EarlyView.
ABSTRACT A new‐type power system serves as a critical technical support for the integration of new energy, and its secure and stable operation is of great importance. However, the extensive utilisation of power electronic devices leads to power equipment insulation being subjected to electrical stresses of high‐frequency harmonics, which can easily ...

Lyapunov‐Function‐Based Stability Region Estimation in Transient Stability Assessment of Inverter‐Based Resources: A Review

High Voltage, EarlyView.
ABSTRACT Electric power systems are undergoing a fundamental transition from synchronous generator (SG)‐dominated systems to inverter‐based resource (IBR)‐dominated systems. Lyapunov‐ and energy‐function‐based direct methods provide an effective way to estimate the stability region, also known as the region of attraction (ROA), and have become a ...

Voltage Control Scheme with Distributed Generation and Grid Connected Converter in a DC Microgrid

Energies, 2014
Direct Current (DC) microgrids are expected to become larger due to the rapid growth of DC energy sources and power loads. As the scale of the system expends, the importance of voltage control will be increased to operate power systems stably.

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.

Assessing Photovoltaic Power Plants With Battery Energy Storage for Capacity Reserve Auctions in Brazil

Energy Storage, Volume 8, Issue 8, December 2026.
ABSTRACT The rapid expansion of variable renewable energy in Brazil has induced severe intraday curtailment, characterized by a pronounced “Duck Curve” driven by transmission limits and regional centralization of generation. This study evaluates the techno‐economic and regulatory feasibility of utility‐scale photovoltaic (PV) plants integrated with ...
