Description
Summary: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.
