Modeling of static var compensator-high voltage direct current to provide power and improve voltage profile

open access: yesInternational Journal of Power Electronics and Drive Systems (IJPEDS), 2021
Transmission lines react to an unexpected increase in power, and if these power changes are not controlled, some lines will become overloaded on certain routes. Flexible alternating current transmission system (FACTS) devices can change the voltage range
