“…The authors of [6], [7] opt to combine the SVR layer with voltage stability indices and TVR, respectively, as a means to account for network vulnerabilities in an optimized manner. A monitoring-based SVR is also the focus of [8], where synchrophasor measurements are applied to reactive power tuning of available generators. Further improvements on the conventional secondary scheme are proposed in [9], [10] through redefinition of static and dynamic control objectives as well as day-ahead dispatch considerations.…”

Voltage and reactive power management is a crucial task for system operators worldwide, and particularly in Norway. While manual operations within regional control centers were once the norm, a major shift is currently ongoing towards coordinated and automatic control strategies such as the secondary voltage regulation (SVR) scheme. However, further research is required to fully understand its effectiveness. This paper aims to contribute in this regard by conducting dynamic simulations of a small test system using a Python-based power system simulator. The study addresses SVR performance for post-fault response, daily load following and voltage setpoint reference change scenarios. Results show that the approach improves overall system voltage profiles, ensures fair reactive power sharing among involved generators and reduces active power losses at the transmission level.
