Operation paradigm of an all converter interfaced generation bulk power system

This study investigates the viability and the associated operational implications of an all converter interfaced generation system operating at constant frequency using grid forming converters. Grid-forming converters set the frequency and voltage of the grid and enable its operation under constant frequency, thus creating a new paradigm for the frequency response of a power system. Power sharing between converters is addressed while assessing the implications of operating the bulk power system at a constant frequency. Case studies performed on a small 9-bus system as well as a large 2000-bus system, using a developed positive sequence as well as a detailed three-phase point on wave models of a grid forming converter are discussed.
