Abstract
A power generation system including a photovoltaic (PV) module to generate DC power is provided. The system includes a combination of a DC to DC converter and a DC to AC converter coupled to the DC to DC converter for supplying power from the PV module to a power grid. The system further includes a bidirectional converter and an energy storage device coupled to the bidirectional converter. The system also includes a control system to generate commands for controlling a state of charge of the energy storage device. The control system comprises a deadband limiter to detect a deviation of the frequency signal outside of a respective signal range, a power shaper to provide a transient power generation adjustment signal in response to the signal being outside of the respective signal range and a limit controller for preventing the adjustment signal from causing the energy storage device to operate outside of at least one operating constraint.
