Strategic and Grid-Aware Maintenance Planning of Offshore Wind Farms
Robert Mieth, Ahmed Aziz Ezzat
Wind turbines require regular maintenance and the resulting costs are a substantial component of a wind farm's cost of electricity production. As a result, there has been ongoing i…
Cross-Temperature Defect Identification in Atomistic Simulations via Multi-Level Domain Alignment
Yating Fang, Jungmin Kim, Qian Qian Zhao +4
Identifying atomic defects at elevated temperature is difficult because thermal fluctuations blur the local symmetry that both geometric heuristics and supervised classifiers rely…
Evaluating Time Series Foundation Models for Electricity Price Forecasting: Contamination Risk, Distributional Shifts, and Covariate Dependence
Zhenghua Pan, Ahmed Aziz Ezzat
Time series foundation models (TSFMs) have shown strong zero-shot forecasting performance, but their generalization in covariate-driven, non-stationary settings is underexplored. E…
A Deep Zero-Inflated Model of North Atlantic Right Whale Presence To Support Blue Economy Management
Jiaxiang Ji, Laura Nazzaro, Ahmed Aziz Ezzat
Effective modeling of endangered marine mammal species, such as the North Atlantic Right Whale, is critical for balancing marine conservation with the growing blue economy. Passive…
Day-Ahead Electricity Price Forecasting Using a Multivariate Group Lasso Method
Keyi Wang, Jiaxiang Ji, Mahan Mansouri +1
Electricity price signals in modern power systems exhibit complex dependence structures that render forecasting inherently challenging. Our analysis of real-world electricity prici…
Accessibility and Serviceability Assessment to Inform Offshore Wind Energy Development and Operations off the U.S. East Coast
Cory Petersen, Feng Ye, Jiaxiang Ji +5
The economic success of offshore wind energy projects relies on accurate projections of the construction, and operations and maintenance (O&M) costs. These projections must conside…
Economic and Reliability Value of Improved Offshore Wind Forecasting in Bulk Power Grid Operation: A Case Study of The New York Power Grid
Khaled Bin Walid, Feng Ye, Jiaxiang Ji +3
This study investigates the economic and reliability benefits of improved offshore wind forecasting for grid operations along the U.S. East Coast. We introduce and evaluate a state…
Joint Optimization of Production and Maintenance in Offshore Wind Farms: Balancing the Short- and Long-Term Needs of Wind Energy Operation
Petros Papadopoulos, Farnaz Fallahi, Murat Yildirim +1
The rapid increase in scale and sophistication of offshore wind (OSW) farms poses a critical challenge related to the cost-effective operation and management of wind energy assets.…
AIRU-WRF: A Physics-Guided Spatio-Temporal Wind Forecasting Model and its Application to the U.S. Mid Atlantic Offshore Wind Energy Areas
Feng Ye, Joseph Brodie, Travis Miles +1
The reliable integration of wind energy into modern-day electricity systems heavily relies on accurate short-term wind forecasts. We propose a spatio-temporal model called AIRU-WRF…
A Surrogate-model-based Approach for Estimating the First and Second-order Moments of Offshore Wind Power
Behzad Golparvar, Petros Papadopoulos, Ahmed Aziz Ezzat +1
Power curve is widely used in the wind industry to estimate power output for planning and operational purposes. Existing methods for power curve estimation have three main limitati…
Seizing Opportunity: Maintenance Optimization in Offshore Wind Farms Considering Accessibility, Production, and Crew Dispatch
Petros Papadopoulos, David Coit, Ahmed Aziz Ezzat
Operations and Maintenance (O&M) constitute a major contributor to offshore wind's cost of energy. Due to the harsh and remote environment in which offshore turbines operate, there…
A Graph-Theoretic Approach for Spatial Filtering and Its Impact on Mixed-type Spatial Pattern Recognition in Wafer Bin Maps
Ahmed Aziz Ezzat, Sheng Liu, Dorit S. Hochbaum +1
Statistical quality control in semiconductor manufacturing hinges on effective diagnostics of wafer bin maps, wherein a key challenge is to detect how defective chips tend to spati…
