Abstract
Techniques are described that not only weigh frequency/voltage and real/reactive load sharing separately, but also utilize a window around a setpoint, such as a percentage of an output range, and determine whether there is oscillation. In response, a control system can adjust a time-independent component of a closed-loop controller to weaken the time-independent component to try and reduce the oscillation. The control system can continue to monitor and weaken the time-independent component until it reaches some limit or until it comes back into control.
