Abstract
A system includes a generator configured to be electrically coupled to a grid, an engine configured to drive the generator, and a solid state generator coupled between the grid and an energy storage device. The system further includes a bias controller configured to detect a frequency of the grid and to responsively provide a bias signal to a speed controller of the engine. The bias controller may include a frequency bias controller configured to generate a frequency bias load sharing signal responsive to the detected frequency of the grid and a load sharing controller that receives the frequency bias load sharing signal and that generates the bias signal responsive to the load sharing signal.
