The influence of multiple factors on the voltage sag level and low computational efficiency also pose challenges to the prediction of residual voltage amplitude of voltage sag. This paper proposes a voltage sag amplitude prediction method based on data fusion. First, the multi-dimensional factors that influence voltage sag residual voltage are analyzed. Second, these factors are used as input, and a model for predicting voltage sag residual voltage based on data fusion is constructed. Last, the model is trained and debugged to enable it to predict the voltage sag residual voltage. The accuracy and feasibility of the method are verified by using the actual power grid data from East China.<\/jats:p>","DOI":"10.3390\/sym14061272","type":"journal-article","created":{"date-parts":[[2022,6,22]],"date-time":"2022-06-22T23:11:19Z","timestamp":1655939479000},"page":"1272","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["A Residual Voltage Data-Driven Prediction Method for Voltage Sag Based on Data Fusion"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4662-7373","authenticated-orcid":false,"given":"Chen","family":"Zheng","sequence":"first","affiliation":[{"name":"Electric Power Research Institute of State Grid Henan Electric Power Company, Zhengzhou 450052, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuangyin","family":"Dai","sequence":"additional","affiliation":[{"name":"Electric Power Research Institute of State Grid Henan Electric Power Company, Zhengzhou 450052, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bo","family":"Zhang","sequence":"additional","affiliation":[{"name":"Electric Power Research Institute of State Grid Henan Electric Power Company, Zhengzhou 450052, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qionglin","family":"Li","sequence":"additional","affiliation":[{"name":"Electric Power Research Institute of State Grid Henan Electric Power Company, Zhengzhou 450052, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuming","family":"Liu","sequence":"additional","affiliation":[{"name":"Electric Power Research Institute of State Grid Henan Electric Power Company, Zhengzhou 450052, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuzheng","family":"Tang","sequence":"additional","affiliation":[{"name":"Electric Power Research Institute of State Grid Henan Electric Power Company, Zhengzhou 450052, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi","family":"Wang","sequence":"additional","affiliation":[{"name":"Electric Power Research Institute of State Grid Henan Electric Power Company, Zhengzhou 450052, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yifan","family":"Wu","sequence":"additional","affiliation":[{"name":"College of Electrical Engineering and Automation, Fuzhou University, Fuzhou 350100, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6834-3390","authenticated-orcid":false,"given":"Yi","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Electrical Engineering and Automation, Fuzhou University, Fuzhou 350100, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,20]]},"reference":[{"key":"ref_1","first-page":"632","article-title":"Voltage Sag Mitigation Strategy for Industrial Users Based on Process Electrical Characteristics-physical Attribute","volume":"41","author":"Zhang","year":"2021","journal-title":"Proc.
