Summary

This paper investigates the evolution of Secondary Voltage Regulation (SVR) in response to the increasing penetration of renewable energy sources (RES) in power systems. Traditional

SVR, historically reliant on fossil fuel-based plants, faces challenges due to their reduced utilization and intermittent operation. As conventional generation declines, emerging resources such as synchronous compensators and STATCOMs provide voltage control capabilities without limiting RES integration, motivating the redesign of SVR control strategies for increasingly dynamic networks. Recent literature highlights a shift toward data-driven approaches that exploit real-world measurements for enhanced control performance. In this context, a new data-driven Secondary Voltage Regulator based on a Model Predictive Control

(MPC) framework is proposed, featuring offset-free tracking and tailored for the Italian transmission system. Field tests on the Sicilian transmission network validate the effectiveness of the proposed controller under real operating conditions.
