Tackling Missing Values in Probabilistic Wind Power Forecasting: A Generative Approach

no code implementations6 Mar 2024 Honglin Wen, Pierre Pinson, Jie Gu, Zhijian Jin

Although it is natural to consider addressing this issue by imputing missing values before model estimation and forecasting, we suggest treating missing values and forecasting targets indifferently and predicting all unknown values simultaneously based on observations.

Deriving Loss Function for Value-oriented Renewable Energy Forecasting

no code implementations1 Oct 2023 Yufan Zhang, Honglin Wen, Yuexin Bian, Yuanyuan Shi

By integrating it into the upper-level objective for minimizing expected operation cost, we convert the bilevel problem to a single-level one and derive the loss function for training the model.

Fast Constraint Screening for Multi-Interval Unit Commitment

no code implementations12 Sep 2023 Xuan He, Jiayu Tian, Yufan Zhang, Honglin Wen, Yize Chen

Extensive simulations on both specific load samples and load regions validate the proposed technique can screen out more than 80% constraints while preserving the feasibility of multi-interval UC problem.

Toward Value-oriented Renewable Energy Forecasting: An Iterative Learning Approach

1 code implementation2 Sep 2023 Yufan Zhang, Mengshuo Jia, Honglin Wen, Yuexin Bian, Yuanyuan Shi

To bridge the gap, we design a value-oriented point forecasting approach for sequential energy dispatch problems with renewable energy sources.

Enabling Fast Unit Commitment Constraint Screening via Learning Cost Model

no code implementations1 Dec 2022 Xuan He, Honglin Wen, Yufan Zhang, Yize Chen

Unit commitment (UC) are essential tools to transmission system operators for finding the most economical and feasible generation schedules and dispatch signals.

Skeleton Sequence and RGB Frame Based Multi-Modality Feature Fusion Network for Action Recognition

no code implementations23 Feb 2022 Xiaoguang Zhu, Ye Zhu, Haoyu Wang, Honglin Wen, Yan Yan, Peilin Liu

To solve the problem, we propose a multi-modality feature fusion network to combine the modalities of the skeleton sequence and RGB frame instead of the RGB video, as the key information contained by the combination of skeleton sequence and RGB frame is close to that of the skeleton sequence and RGB video.
