    Abstract: A method for regulating a power line voltage includes determining a slow voltage variation by filtering an actual voltage at terminals of the voltage regulation apparatus. A fast active power variation is determined by filtering a measured active power of the DG system; wherein a first frequency of the slow voltage variation is smaller than a second frequency of the fast active power variation. The voltage regulation apparatus settings are controlled based on the slow voltage variation and a reactive power output of the DG system is controlled based on fast active power variation.

    Abstract: A power conversion system (10) configured to provide AC power to a transformer (28) is described. The power conversion system includes a power conversion device (14) that includes a device input (42) and a device output (62). The power conversion device is configured to receive power from a power source (12) at the device input and the device output is configured for coupling to a transformer input (46). The power conversion system also includes a sensor (20) coupled at a first point of interconnection (50) between the device output and the transformer input and is configured to measure a voltage level at the first point of interconnection. The power conversion system also includes a system controller (18) communicatively coupled to the power conversion device and the sensor. The system controller is configured to determine an impedance of the power grid (30) based at least partially on the voltage level at the first point of interconnection.
