Abstract Massive energy storage capability is tending to be included into bulk power systems especially in renewable generation applications, in order to balance active power and maintain system security.
The battery energy storage system (BESS) is integrated into the secure (protected by the DU) dc link at the receiving-end station, with only dc current going through during its normal operation, thereby extending lifetime and reducing losses; 4) For the BESS, scalable design/sizing and effective management are feasible due to the modular structure;
