Robust Coordinated Reserve Optimization Method for Electricity–Gas Systems Considering Multi‐Source Coupling and Multiple Uncertainties

Energy Science &Engineering, EarlyView.
This study proposes a two‐stage robust reserve optimization method for coupled electricity–gas systems to mitigate wind–solar fluctuations and transmission‐line contingencies. By coordinating cross‐network reserves and linearizing complex gas flow equations, the approach significantly enhances system security and economic efficiency under multiple ...

Electrolyzer Sizing and Techno‐Economic Assessment of Small‐Hydropower‐Based Green Hydrogen Using 3 Years of Hourly Generation Data

Energy Science &Engineering, EarlyView.
Three years (26,280 h) of measured Miryang Dam hydropower data were used to screen 300–1200 kW PEM electrolyzer capacities. A 600 kW unit provided the equal‐weight technical balance between hydropower capture (84.71%) and electrolyzer utilization (86.25%), whereas the planned 1 MW design captured 98.11% of available renewable energy but operated at a ...

Influence of Adhesive Type on Heat Induced Delamination in Tension Loaded Shear Lap Cross‐Laminated Timber Samples Exposed to Radiant Heat Flux

Fire and Materials, EarlyView.
ABSTRACT Heat induced delamination (HID) is a phenomenon in engineered wood products which may result in the detachment of the bonded timber lamellae before charring propagates to the bond line interphase. This study aims to correlate the thermal degradation of two 1‐c‐polyurethane adhesives at the microscale to the thermo‐hydro‐mechanical behaviour of

ACT and district pumped hydro energy storage (PHES) atlas

, 2017
The ACT has relatively few potential sites for pumped hydro energy storage (PHES) sites due to the large fraction of the territory's mountains that is occupied by Namadgi National Park.

Remote Sensing for Irrigation Water Management—The State of the Art and Prospects for Near‐Future Operations

Irrigation and Drainage, EarlyView.
ABSTRACT A recent UN report describes many regions as facing ‘water bankruptcy,’ a condition in which available water resources can no longer meet existing demands. In practice, this means irrigation will likely bear the greatest burden of future water‐use reductions, a complicated and fraught decision to make given its critical role in food security ...
