How BESS, PCS, and EMS Communicate: A Behind-the-Scenes
But have you ever wondered how the components within a BESS communicate to make this possible? Let''s delve into the intricate dance between the Power Conversion
The mobility and flexibility of the system enables novel applications and deployments where BESS previously were unused due to the non-flexible solutions. The system is modular, meaning that the energy storage capacity can be quickly adapted depending on the application case, in contrast to larger and bulkier solutions.
The system is built of two main blocks. The PCS building block, responsible for the main control of the mobile BESS. The nominal power rating of the PCS block is 225 kVA, with a maximum peak power in the peak shaving mode of 275 kW . The second block is the modular battery pack.
Accommodating novel and state-of-the-art BESS coordination and protection capabilities. Furthermore, such a coordination scheme could be utilized to efectively connect multiple VMS and other mobile BESS in an efective manner, for an interoperable coordinated mobile system DER.
The investigation compares the identified communication interfaces and their respective applicability to a mobile BESS, specifically the VMS. For specific power utility applications, it is clearly noted that the standard IEC 61850 allows clear benefits compared to the other investigated interface.
