Abstract
A reconnection control apparatus controls a switch disposed between at least one DER system having droop characteristics and a power grid. The reconnection control apparatus comprising a first detecting unit to detect first phase, frequency and amplitude of a voltage on a side of the DER system of the switch a second detecting unit to detect second phase, frequency and amplitude of a voltage on a side of the power grid of the switch and a reconnection control unit to reconnect the DER system to the power grid by outputting power reference and voltage reference signals to the DER system to match the first phase, frequency and amplitude to the second phase, frequency and amplitude and closing the switch based on a difference between the first phase and the second phase and a difference between the first absolute and the second absolute.
