Stochastic Optimal Power Flow in Hybrid Power System Using Reduced-Discrete Point Estimation Method and Latin Hypercube Sampling [PDF]

, 2022
Stochastic nature of some input variables dictates the requisite of probabilistic analysis in power systems operation and planning. Wind generation is considered as a main source of intermittency in power systems due to the uncertain nature of wind speed.

Prediction of Pile Bearing Capacity Using Opposition‐Based Differential Flower Pollination‐Optimized Least Squares Support Vector Regression (ODFP‐LSSVR)

Advances in Civil Engineering, Volume 2022, Issue 1, 2022., 2022
Pile foundations are widely used for high‐rise structures constructed in soft ground. The bearing capacity of pile is a crucial parameter required during the design and construction phase of pile foundation engineering projects. In practice, accurate predictions of pile bearing capacity are challenging due to a complex interplay of various geotechnical

Data‐Driven Electricity Price Risk Assessment for Spot Market

International Transactions on Electrical Energy Systems, Volume 2022, Issue 1, 2022., 2022
Electricity price risk assessment (EPRA) is essential for spot market analysis and operation. The statistical moments (i.e., the mean and standard deviation) of the price need to be assessed to support market risk control. This paper proposes a data‐driven approach for EPRA based on the Gaussian process (GP) framework.

Early Post‐Operative Pancreatitis and Systemic Inflammatory Response Assessed by Serum Lipase and IL‐6 Predict Pancreatic Fistula

World Journal of Surgery, Volume 44, Issue 12, Page 4236-4244, December 2020., 2020
Abstract Background Post‐operative pancreatic fistula (POPF) remains a critical complication after pancreatic resection. This prospective pilot study evaluates perioperative markers of pancreatitis and systemic inflammation to predict clinically relevant grade B/C‐POPF (CR‐POPF).
