AUTONOMOUS REGULATION OF GRID EDGE DEVICES
Disclosed are approaches for autonomously regulating grid edge devices (GEDs). In one embodiment, an average reactive power value is determined, corresponding to reactive power generated by a GED over a time interval. An average voltage value is determined, corresponding to voltage received by the GED over the time interval. A setpoint voltage for the GED is updated based at least in part on the average reactive power value and a difference between the setpoint voltage and the average voltage value that exceeds a voltage threshold value.
