Claim 9:
10. A method of a power system comprising a power inverter coupled to a power source through a DC bus, and an energy storage power converter coupled between the DC bus and an energy storage unit, the method comprising:
determining a change in an output power of the energy storage power converter; determining a change in a voltage at the DC bus;
autonomously detecting curtailment on the power inverter according to the change in an output power of the energy storage power converter and the change in a voltage at the DC bus;
in response to detecting that the power inverter is not curtailed, controlling the energy storage power converter to adjust a discharge power command for commanding the energy storage power converter to discharge an amount of power from the energy storage unit according to whether the output power of the power source has decreased, wherein the controller is configured to iteratively adjust the discharge power command by a predetermined power discharge adjustment value whose sign is reversed from positive to negative or from negative to positive according to whether the output power of the power source has decreased.
