  • Apparatus and methods for reducing generator frequency variation
    Patent number: 11418039
    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.
    Type: Grant

  • Transient power stabilization device with active and reactive power control
    Patent number: 10574055
    Abstract: A system includes a converter configured to be coupled between an energy storage unit and a grid and a control circuit configured to detect frequency and voltage variations of the grid and to responsively cause the converter to transfer power and reactive components to and/or from the grid. The control circuit may implement a power control loop having an inner frequency control loop and a reactive component control loop having an inner voltage control loop. The control circuit may provide feedforward from the inner frequency control loop to the inner voltage control loop to inhibit reactive component transfer in response to a voltage variation deviation of the grid due to a power transfer between the energy storage unit and the grid.
