The transmission line selected as a candidate for the potential conversion from HVAC to HVDC is the 220 kV Partanna-Partinico double three-phase circuit.<br \/>\nIdentifying 2030 as the starting work point, the static analysis of the Sicilian network via power flow execution with nonlinear models implemented in the DIgSILENT (PowerFactory) tool has allowed identifying the effects of the line conversion from HVAC to HVDC on the system electrical quantities, including voltage and reactive power.<br \/>\nThe evaluation of the main technical-economic indices for the HVAC-to-HVDC line conversion has been carried out according to the methodology and with the REMARK+ tool developed by RSE, based on optimization algorithms (OPF, Optimal Power Flow). The results show that the conversion of the Partanna-Partinico line from HVAC to HVDC in a 2030 scenario allows for improving the dispatching of the system, with consequent overall reductions in production costs, CO2 emissions, and network congestion.<\/p>\n","link_estreno":false,"scarica_file":[{"download_option":"download","file_name":"Download Report","download":{"ID":173396,"id":173396,"title":"21008887","filename":"21008887.pdf","filesize":2026617,"url":"https:\/\/www.rse-web.it\/wp-content\/uploads\/2022\/11\/21008887.pdf","link":"https:\/\/www.rse-web.it\/en\/rapporti\/benefici-tecnico-economici-di-sistema-derivanti-dalla-conversione-di-un-collegamento-da-hvac-a-hvdc\/attachment\/21008887\/","alt":"","author":"93","description":"","caption":"","name":"21008887","status":"inherit","uploaded_to":173395,"date":"2022-11-11 13:56:08","modified":"2022-11-11 13:56:08","menu_order":0,"mime_type":"application\/pdf","type":"application","subtype":"pdf","icon":"https:\/\/www.rse-web.it\/wp-includes\/images\/media\/document.png"}}],"button":{"text":"","link":""},"referente_group":false,"data_emissione":"2021-12-31","autori":"A.
