Description
of P versus Frequency Droop
w = 2 p f
wo
P
Po
Pmax
Output of Droop, Proportional to Frequency
Nominal, Steady State Grid Frequency
D w
D P
Droop with Fixed Slope
Power Setpoint with Grid
Prime Mover Maximum Output
The Measure of P is the Input of the Droop
Given the
Measure of Power,
P, the
Droop Generates a
Value for
the Frequency
