Example
1) Increased the load ratio up to 100%
Output frequency decreased by the amount of load
2) Put 100% step load and removed 100% load in a moment
Put the step load (100%) for 8 seconds and then remove the step load.
The droop control decreased the output frequency for '43.06' (Droop ramp time) = 5s at step load.
The droop control increased the output frequency for '43.06' (Droop ramp time) = 5s at no step load.
