Bi‐level capacity planning for park IES considering energy supply reliability

Energy Conversion and Economics, EarlyView.
Abstract Carbon emissions and energy consumption of urban buildings represent a notable fraction of global energy utilization. In pursuit of the “carbon peaking and carbon neutrality” goals, urban park building integrated energy system (IES) energy saving technology is regarded as a key technology to achieve sustainable urban development.

Investigating Breathing Dynamics of a 110 kV Oil‐Immersed Transformer Using Thermal‐Fluid‐Structure Interaction Modelling

High Voltage, EarlyView.
ABSTRACT The breathing system of an oil‐immersed transformer is of vital importance for maintaining equilibrium between internal and external pressures, with any malfunction potentially disrupting the transformer's stable operation. This study develops a thermal–fluid–structure interaction (TFSI) model to simulate the breathing phenomenon in a 110 kV ...

Study of Positive Corona Discharge of Needle Plate Electrodes in Airflow

High Voltage, EarlyView.
ABSTRACT For high‐speed moving objects such as aircraft and wind turbine blades, discharge occurs under strong airflow. Research on lightning attachment characteristics has been extensive, whereas the role of corona discharge in pre‐breakdown streamer development has received less attention.

Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures

High Voltage, EarlyView.
ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.

Tubes or Ribbons? Comparing Texture‐space Visualization for Multivariate Line Data

Computer Graphics Forum, EarlyView.
Abstract Multivariate line data is critical for analyzing flow fields, agent systems, and dynamic trajectories. Embedding secondary variables along spatial paths using surface‐based primitives such as ribbons and circular tubes introduces challenges related to perspective, scale, and distortion.

Quantifying Fiber Bridging in Mode I Fatigue Delamination of CFRP/GFRP Hybrid Laminates Using a Superposed Traction–Separation Model

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Hybrid CFRP/GFRP laminates offer an attractive balance between mechanical performance, damage tolerance, and cost efficiency. However, fiber bridging during mode I delamination increases crack‐growth resistance while masking the intrinsic fatigue behavior of the material. This study applies a traction–separation‐based superposition approach to

Dynamic Capabilities as Drivers of Circular Business Models: Exploring Direct and Indirect Relationships

Journal of Product Innovation Management, EarlyView.
ABSTRACT Academic Summary Despite the urgent need for a circular economy, firms' transition from linear to circular business models (CBMs) remains slow. While previous research suggests that dynamic capabilities are the key drivers of this transition, it assumes a direct link, overlooking that these capabilities can facilitate change but do not ...

Structural Characteristics of Wind Turbines with Different Blade Materials Under Yaw Condition

Energies
The uneven distribution of airflow on the blade surface of a yaw wind turbine triggers a complex non-constant flow, resulting in turbine flow field operation disorder, which, in turn, affects the structural field.

Estimating Wind‐Power Capacity Time Series From Production Data Using a Power Curve Model and Quadratic Optimization

Wind Energy, Volume 29, Issue 8, August 2026.
ABSTRACT Accurate, time‐resolved installed capacity data are crucial for forecasting and analysing wind‐power production. The time series of installed capacity is often only approximately known in regions with rapid wind power development. Public wind power databases may only be updated yearly and installation dates may not be differentiated within ...
