Abstract

This paper explores a novel control scheme for utility-scale inverter-based resources (IBR), which emulates synchronous generator behavior during fault conditions. This will ensure reliability of transmission-line protective devices, such as distance relays, which rely on the unbalanced currents traditionally produced by synchronous generators to accurately determine the fault location. As the generation profile of the grid continues to trend towards a higher penetration of renewables these relays will not be adequate, thus necessitating costly equipment upgrades. By implementing the proposed control scheme, existing relays will continue to operate properly and the need for any such equipment upgrades is eliminated.
