APPARATUS AND METHOD FOR SUPPLYING POWER TO OR ABSORBING POWER FROM A LOAD

Abstract: an apparatus is configured to supply power to a load or absorb power from the load, the load being connected or connectable to a load conductor. the apparatus comprises a power supplying and/or absorbing device, configured for selectively supplying power to the load conductor or absorbing power from the load conductor, and a control unit configured to control the power supplying and/or absorbing device. the control unit is configured to determine, based on at least one value indicative of voltage of the load conductor and a virtual impedance of the power supplying and/or absorbing device, a voltage reference value for the power supplying and/or absorbing device, and control the power supplying and/or absorbing device to supply power to the load conductor, and thereby supply power to the load, or absorb power from the load conductor, and thereby absorb power from the load, based on the determined voltage reference value.
