A General Equivalent Modeling Method for DFIG Wind Farms Based on Data-Driven Modeling

open access: yesEnergies, 2022
To enhance the stable performance of wind farm (WF) equivalent models in uncertain operating scenarios, a model-data-driven equivalent modeling method for doubly-fed induction generator (DFIG)-based WFs is proposed.

Three Vectors Model Predictive Torque Control Without Weighting Factor Based on Electromagnetic Torque Feedback Compensation

open access: yesEnergies, 2019
Finite control set-model predictive torque control (FCS-MPTC) depends on the system parameters and the weight coefficients setting. At the same time, since the actual load disturbance is unavoidable, the model parameters are not matched, and there is a ...

Multi-Loss Weighting with Coefficient of Variations [PDF]

open access: yes2021 IEEE Winter Conference on Applications of Computer Vision (WACV), 2021
Many interesting tasks in machine learning and computer vision are learned by optimising an objective function defined as a weighted linear combination of multiple losses. The final performance is sensitive to choosing the correct (relative) weights for these losses.
