Energy storage serves as the "stabilizer, dispatcher, and backup power core" of a microgrid:
1、In off-grid mode, it establishes voltage and frequency reference (using VSG technology) to support microgrid operation.
2、It smooths out random fluctuations from PV and wind power.
3、It adjusts when generation (source) and demand (load) are mismatched.
4、It provides black start capability during faults.
