An electric power source includes: a battery defining a state of charge; a converter in electrical communication with the battery; and a controller in operable communication with the converter, the controller including a compensation toggle circuit configured to provide a compensation toggle value based on a power output of the battery; a dynamic droop control circuit configured to receive the compensation toggle value and switch an output droop value of the dynamic droop control circuit from an upper output droop measurement to a lower output droop measurement, wherein the lower output droop measurement is based on the state of charge of the battery.
