What Is 3-Phase Power?, Part 9: Droop Control
From the series: What Is 3-Phase Power?
In 3-phase electrical power systems, grid-forming controllers establish and regulate voltage and frequency. Droop control is a grid-forming control mechanism that has the added benefit of enabling precise power sharing between generators. You will learn:
- How constant frequency (isochronous) control regulates frequency to a given setpoint regardless of active power output
- How constant voltage control regulates voltage to a given setpoint regardless of reactive power output
- How droop control is a simple and elegant solution to stability problems that can arise with constant frequency and constant voltage control
- How frequency droop directly controls active power
- How voltage droop directly controls reactive power
