This study deeply analyzes the multi\u2010energy flow coupling structure and operation mechanism of multi\u2010energy systems, and carries out the power flow calculation and analysis of multi\u2010energy systems based on an energy hub, so as to ensure the safe and stable operation of regional energy. Based on the physical characteristics of energy systems such as power systems, thermal systems, and gas systems, this article studies the comprehensive power flow model including the electric\u2010gas\u2010thermal multi\u2010energy coupling network and proposes the power flow decomposition of the energy supply subsystem and its applicable equation based on Newton\u2013Raphson method. The effectiveness of the proposed method under different operation modes is verified by case studies. The calculation results show that under constant load, the energy hub running in fixing thermal by electricity (FEL) and fixing electricity by thermal (FTL) mode has little influence on the voltage of each node in the power sub\u2010network. Within the constraint range, the natural gas flow obtained from the natural gas subsystem is coupled with the power subsystem to meet the load demand. The influence on the power flow at each node of the heat network is not obvious.<\/jats:p>","DOI":"10.1155\/2022\/2698226","type":"journal-article","created":{"date-parts":[[2022,9,5]],"date-time":"2022-09-05T20:35:07Z","timestamp":1662410107000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Integration and Modeling of Multi\u2010Energy Network Based on Energy Hub"],"prefix":"10.1155","volume":"2022","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5001-8853","authenticated-orcid":false,"given":"Min","family":"Mou","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuhao","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenguang","family":"Zheng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yurong","family":"Xie","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,9,5]]},"reference":[{"key":"e_1_2_10_1_2","doi-asserted-by":"publisher","DOI":"10.1109\/jproc.2010.2052776"},{"key":"e_1_2_10_2_2","first-page":"3292","article-title":"Review of steady-state analysis of typical regional integrated energy system under the background of energy internet","volume":"36","author":"Wang W.","year":"2016","journal-title":"Proceedings of the CSEE"},{"key":"e_1_2_10_3_2","volume-title":"Model Research and Evaluation Analysis of User-Based Building Distributed Energy Supply System","author":"Li T.","year":"2013"},{"key":"e_1_2_10_4_2","volume-title":"Research on Modeling and Optimization of Distributed Energy Network Based on Energy Hub","author":"Zhang G.","year":"2021"},{"key":"e_1_2_10_5_2","first-page":"9","article-title":"Modeling and multi-objective optimal dispatch of micro energy grid based on energy hub","volume":"47","author":"Chen L.","year":"2019","journal-title":"Power System Protection and Control"},{"key":"e_1_2_10_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.egypro.2014.11.928"},{"key":"e_1_2_10_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.apenergy.2015.01.013"},{"key":"e_1_2_10_8_2","first-page":"3634","article-title":"Research on hybrid power flow algorithm of electricity\/gas\/heat in regional integrated energy system","volume":"35","author":"Xu X.","year":"2015","journal-title":"Proceedings of the Chinese Society for Electrical Engineering"},{"key":"e_1_2_10_9_2","doi-asserted-by":"publisher","DOI":"10.1109\/tpwrs.2013.2283259"},{"key":"e_1_2_10_10_2","first-page":"5829","article-title":"Xiaolong Jin, et al.
