Coordinated control of grid-forming converters and hydro generators to enhance frequency quality of future power system

The aim of this paper is to propose a coordinated control strategy between grid-forming converters equipped with energy storage, and hydro generators facilitate frequency support from the in future power systems. In way, it possible take advantage fast dynamic properties converter system, at same time minimize storage requirements associated system. proposed tuning criterion for controller facilitates natural coordination system generators. effectiveness compared against conventional droop-based approach available literature. Finally, analytical findings are validated using detailed time-domain simulation model PSCAD.
