Firstly, the new algorithm uses improved cloud model to calculate the digital features of station area and users\u2019 voltage sequences quickly. Secondly, the paper uses the adaptive segmentation voltage algorithm to divide the full voltage sequences into three parts automatically to add local features into phase identification. Finally, the paper calculates cosine similarity between each segmented voltage cloud model to identify users\u2019 voltage phase. The analysis based on station data and field verification shows that the new algorithm has not only improved the calculation efficiency by 41% compared with traditional user phase identification algorithm, but also increased the difference in identification results between different phases by 1000 times. In the final result, the accuracy of the new algorithm is 95%. The new algorithm has more obvious differentiation and higher accuracy. The analysis results based on the actual engineering data also prove the feasibility and effectiveness of the new user phase identification algorithm.<\/jats:p>","DOI":"10.3233\/jifs-232415","type":"journal-article","created":{"date-parts":[[2023,9,5]],"date-time":"2023-09-05T11:47:05Z","timestamp":1693914425000},"page":"8583-8594","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Research on user phase identification algorithm based on improved cloud model and adaptive segmented voltage"],"prefix":"10.1177","volume":"45","author":[{"given":"Liang","family":"Guo","sequence":"first","affiliation":[{"name":"State Grid Baoding Power Supply Company, Baoding, Hebei, China"}]},{"given":"Junzhao","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Grid Baoding Power Supply Company, Baoding, Hebei, China"}]},{"given":"Peiyi","family":"Dong","sequence":"additional","affiliation":[{"name":"State Grid Baoding Power Supply Company, Baoding, Hebei, China"}]},{"given":"Yuanzheng","family":"Wan","sequence":"additional","affiliation":[{"name":"State Grid Baoding Power Supply Company, Baoding, Hebei, China"}]},{"given":"Wenhui","family":"Li","sequence":"additional","affiliation":[{"name":"Henan University","place":["China"]}]}],"member":"179","published-online":{"date-parts":[[2023,9,2]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/OAJPE.2021.3067632"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/TPWRS.2020.3011133"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/TSG.2019.2952080"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1109\/TPWRS.2020.2965770"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","unstructured":"OveringtonS.
