## droop

The deviation from a preset value of a controlled liquid level, temperature, variable pressure, or differential pressure (at minimum controllable flow) when the flow through a regulator is gradually increased from its minimum controllable flow to its rated capacity.

## droop

i. A downward curvature of the leading edge of an airfoil to provide increased camber.
ii. A progressive decrease in RPM that occurs when a fuel control flyweight governor spring is extended and made weaker. It takes less flyweight force to come to an equilibrium with the weaker spring force and consequently a lower RPM will result.
iii. The inability of the engine power to increase as the rotor pitch is increased, causing the rotor to slow down.

The proposed method ensures synchronization in the output voltage level by adjusting the reference voltage according to the droop method.
where [m.sub.p] is the proportion a droop coefficient of active power, [m.sub.d] is the differential coefficient of active power, [n.sub.p] is the proportion of a droop coefficient of reactive power, Mj is the integral coefficient of reactive power, and [n.sub.d] is the differential coefficient of reactive power.

In the same way, the small-signal dynamics of the conventional Q-E droop can be obtained by linearizing equations (2) and (10) at operation points [Q.sub.o], [[delta].sub.0], and [[delta].sub.go] as follows:
droop = (1 - [[[eta].sub.high-current]/[[eta].sub.max]]) x 100%.
