Implemented Power Factor Compensation and Monitoring System (PFCMS) calculates the optimal capacitor combination to improve power factor of the installation by measure of voltage, current, and active power. CBO algorithm determines the best solution of capacitor values to install, by applying TLBO in different phases of the algorithm. Electrical variables acquired by the sensors and the variables calculated are stored in CDL using Google Sheets (GS) to monitor and analyse the installation by means of a TLBO algorithm implemented in PFCMS, that optimizes the compensation power factor of installation and determining which capacitors are connected in real time. Moreover, the optimization of the power factor in facilities means economic and energy savings, as well as the improvement of the quality of the operation of the installation.<\/jats:p>","DOI":"10.3390\/s19092172","type":"journal-article","created":{"date-parts":[[2019,5,13]],"date-time":"2019-05-13T03:57:07Z","timestamp":1557719827000},"page":"2172","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["Power Factor Compensation Using Teaching Learning Based Optimization and Monitoring System by Cloud Data Logger"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6440-021X","authenticated-orcid":false,"given":"Antonio","family":"Cano Ortega","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, University of Jaen, 23071 EPS Jaen, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9508-1728","authenticated-orcid":false,"given":"Francisco Jose","family":"S\u00e1nchez Sutil","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, University of Jaen, 23071 EPS Jaen, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9117-1689","authenticated-orcid":false,"given":"Jes\u00fas","family":"De la Casa Hern\u00e1ndez","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, University of Jaen, 23071 EPS Jaen, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,5,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"303","DOI":"10.1016\/j.cad.2010.12.015","article-title":"Teaching\u2013learning-based optimization: A novel method for constrained mechanical design optimization problems","volume":"43","author":"Rao","year":"2011","journal-title":"Comput.
