Generator Load Sharing - Droop

Real-power split between two generators in droop mode when the grid frequency shifts.

Gen 1 share
1.56MW
Gen 2 share
1.94MW

Formula, assumptions, and limits

Set all governors to the same droop (typical 4 %) to share load in proportion to rating. Unequal droops give proportional unbalance. Isochronous mode (one gen at 0 % droop) takes all load swings on that unit - useful only for emergencies.
