The concepts of smart metering, a smart home, and an electric car are developing simultaneously with the idea of a smart city by developing high-performance electrical equipment and systems, telecommunications technologies, and computing and infrastructure based on artificial intelligence algorithms. The article presents contributions regarding the modeling of consumer classification and load profiling in electrical power networks and the efficiency of clustering techniques in their profiling as well as the simulation of the load of medium-voltage\/low-voltage network distribution transformers to electricity meters.<\/jats:p>","DOI":"10.3390\/s23041895","type":"journal-article","created":{"date-parts":[[2023,2,8]],"date-time":"2023-02-08T03:57:16Z","timestamp":1675828636000},"page":"1895","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Contributions to Power Grid System Analysis Based on Clustering Techniques"],"prefix":"10.3390","volume":"23","author":[{"given":"Gheorghe","family":"Grigora\u0219","sequence":"first","affiliation":[{"name":"Department of Power Engineering, \u201cGheorghe Asachi\u201d Technical University of Iasi, 700050 Iasi, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7277-4377","authenticated-orcid":false,"given":"Maria Simona","family":"Raboaca","sequence":"additional","affiliation":[{"name":"National Research and Development Institute for Cryogenic and Isotopic Technologies\u2014ICSI Rm.
