Performance assessment of grid-forming and grid-following converter-interfaced battery energy storage systems on frequency regulation in low-inertia power grids

Mario Paolone, Sidi-Rachid Cherkaoui, Fabrizio Sossan, Yihui Zuo, Antonio Zecchino, Zhao Yuan

Power systems with large shares of converter-interfaced renewables may be characterised by low grid inertia due to the lack of frequency containment provided by synchronous generators. Battery energy storage systems (BESSs), which can adjust their power ou ...
