Grid-Forming Energy Storage In Fast Frequency Regulation Of Renewable Micro-grid

This proposed a fast frequency regulation method for renewable micro-grid based on grid-forming energy storage (GFM-ES). Firstly, the main circuit and control system of grid-forming energy storage is introduced. Then, with the case study presented in this paper, the function of GFM-ES in suppression of frequency change rate and frequency nadir is validated with a time-domain simulation, which are the critical index and dominate the security of micro-grid.
