Droop control curve in microgrid
In droop control, frequency and voltage “droop” values are assigned to each generation unit in the grid. While widely utilised, Conventional Droop Control (CDC) techniques often. . In islanded low-voltage microgrids, the parallel operation of inverters using traditional droop control strategies often results in imbalanced output impedances among inverters due to variations in line impedance. These characteristics follow linear relation between active power and frequency and reac-tive power and voltage. [pdf]
