Measurement-Based Voltage Control Coordinating Inverter-Based Resources and Traditional Resources - New York State Grid Case Study

Inverter-based resources (IBRs) are being increasingly integrated into power systems around the world. While they may pose a challenge to power grids due to inherent volatility, they can be used as a voltage control resource due to their control flexibility. By utilizing this control flexibility combined with the increasingly available synchronized measurement and communication infrastructure of modem power systems, this paper proposes a measurement-based voltage control scheme that coordinates IBRs with traditional resources such as synchronous generators and Flexible AC Transmission Systems (FACTS) devices for voltage control. The integration of real-time synchronized measurements allows the control scheme to provide a robust performance against varying operating conditions, modeling uncertainties, and load variations. The control scheme allows flexible coordination of various voltage control resources by configuring parameter combinations. The effectiveness and performance of the proposed controller have been validated using a hardware-in-the-loop (HIL) platform.
