In the context of accelerating the construction of new power systems,distributed smart grids are increasingly encountering scenarios involving islanded operation,leading to increased operation difficulty.There is an urgent need for grid-forming energy storage to support their safe and stable operation.Firstly,the connotations and attributes of distributed smart grids and distributed islanded grids are given.Furthermore,from the perspectives of supply and demand balance,stability,and reliability of distributed islanded grids,the main challenges faced by distributed islanded grids are analyzed and summarized.Secondly,the control methods for grid-forming energy storage are analyzed,specifically including droop control,virtual synchronous generator control,matching control,and virtual oscillator control.Based on this,a multi-level control architecture for grid-forming energy storage is proposed.Then,the applications of grid-forming energy storage in enhancing regulation capability,steady-state operation,and operation under disturbances of distributed islanded grids are discussed.Finally,combining the current research status,thoughts and suggestions are proposed from the aspects of efficient planning,optimal operation,and intelligent control.
