Local relaxation of residual stress in high-strength steel welded joints treated by HFMI
Alain Nussbaumer, Yuki Ono, Heikki Tapani Remes
This research studies the influence of high-peak loads on local relaxation of residual stress and fatigue damage in highstrength steel welded joints treated by high-frequency mechanical impact (HFMI) treatment. The joint behavior is simulated with elastic– ...
2024Data-Driven Reactive Power Optimization of Distribution Networks via Graph Attention Networks
Wenlong Liao, Qi Liu, Zhe Yang
Reactive power optimization of distribution networks is traditionally addressed by physical model based methods, which often lead to locally optimal solutions and require heavy online inference time consumption. To improve the quality of the solution and r ...
State Grid Electric Power Research Inst2024Beyond the average consumer: Mapping the potential of demand-side management among patterns of appliance usage
Claudia Rebeca Binder Signer, Selin Yilmaz, Matteo Barsanti
To support the decarbonisation of the power sector and offset the volatility of a system with high levels of renewables, there is growing interest in residential Demand-Side Management (DSM) solutions. Traditional DSM strategies require consumers to active ...
2024Federated Reinforcement Learning for Electric Vehicles Charging Control on Distribution Networks
Yuning Jiang, Wei Chen, Xin Liu, Ting Wang
With the growing popularity of electric vehicles (EVs), maintaining power grid stability has become a significant challenge. To address this issue, EV charging control strategies have been developed to manage the switch between vehicle-to-grid (V2G) and gr ...
Ieee-Inst Electrical Electronics Engineers Inc2024Reliability and Long-term Performance of Building Integrated Photovoltaic (BIPV) Modules
Solar photovoltaics (PV) is one of the most competitive renewable energy technologies in order to meet the increasing global energy demand and decrease CO2 emissions by competing effectively with fossil fuels. One of the important applications of PV energy ...
EPFL2024Tension-tension fatigue behavior of basalt composite hybrid joints
Thomas Keller, Lulu Liu, Xin Wang
The tension–tension fatigue behavior of pseudo-ductile hybrid bonded-bolted double lap basalt composite joints, composed of pseudo-ductile adhesives and adherends with multi-directional fiber architecture, was experimentally investigated. The fatigue damag ...
2024The thermodynamic and life-cycle assessments of a novel charging station for electric vehicles in dynamic and steady-state conditions
Jan Van Herle, Hossein Pourrahmani, Chengzhang Xu
The current study performs the thermodynamic and life-cycle assessments (LCA) of a novel charging station in two system designs. The goal is to design an efficient charging station for electric vehicles with high efficiencies and low environmental impacts ...
NATURE PORTFOLIO2023Homogenous power distribution along gyrotron collector walls
Stefano Alberti, Jean-Philippe Hogge, Damien Fasel, Ugo Siravo, Jérémie Dubray, Miguel Filipe Silva Füglister, Pierre-François Isoz
EC RF power sources will play a major role in the future operation of large scale tokamaks (ITER, DEMO). A 1MW/170GHz gyrotron is the standard RF power unit considered for ITER. Even though the efficiency of such devices has been significantly increased th ...
2023Stochastic-robust planning optimization method based on tracking-economy extreme scenario tradeoff for CCHP multi-energy system
The load tracking performance of combined cooling, heating, and power multi-energy system (CCHP-MES) greatly depends on the equipment capacity configuration. And the frequent fluctuations in the source-load uncertainty puts higher demands on the load track ...
PERGAMON-ELSEVIER SCIENCE LTD2023Experimental Validation of Model-less Robust Voltage Control using Measurement-based Estimated Voltage Sensitivity Coefficients
Mario Paolone, Rahul Kumar Gupta
Increasing adoption of smart meters and phasor measurement units (PMUs) in power distribution networks are enabling the adoption of data-driven/model-less control schemes to mitigate grid issues such as over/under voltages and power-flow congestions. Howev ...
