A remote electrical node away from the IBR is determined where compliance with grid code current injection requirements during a transient power event on the grid are evaluated. An impedance from the IBR to the remote electrical node is estimated and, based on the estimated impedance and the local voltage feedback signal, a remote voltage feedback signal is generated for the electrical node. Control signals are generated to control or limit current injection to the grid from the IBR based on the remote voltage feedback signal. The IBR is operated according to the control signals so that the current injected to grid as determined at the remote electrical node follows the grid code current requirements.
