The most common type of droop control is conventional droop control. In conventional droop control, frequency and voltage vary linearly with respect to active and reactive power, respectively. For instance, assigning a 1% frequency droop to a converter means that its frequency deviates 0.01 per unit (pu) in response to a 1.0 pu change in active power.
