Abstract
A network subscriber unit for an electrical energy supply network includes a control unit configured to control the power exchange of the network subscriber unit with the energy supply network, a device configured to determine a voltage zero crossing at a connection point of the network subscriber unit with the energy supply network and a receiving unit of the network subscriber unit configured to receive a signal of a reference time. The control unit is in this case configured to determine a time offset between a time of the voltage zero crossing determined by the device and the received reference time and to control the power exchange based on the time offset.
