Technical FAQs 4

What is the most innovative communication standard for power system communication?

First, applicable communication standards are investigated and especially the usage of IEC 61850 as the most innovative standard for power system communication is analyzed according to the needs for BESS (Section II).

What makes a Bess a good system?

Scalability: Standardized protocols like Modbus make it easier to integrate additional components or expand the system. The synergy between the PCS and EMS, facilitated by RS485 and Modbus communication, is the backbone of an efficient BESS.

What is a Bess communication concept?

A concept for communication for BESS was devised based on the standard IEC 61850. It has been shown, that additions to the IEC 61850 standard are necessary to make it suitable for implementing the identified requirements on the integration of a BESS in the electrical grid.

How does a Bess work?

Action Execution: The PCS receives the command and executes the required operation. Feedback Loop: The PCS then sends a status update back to the EMS, confirming the action or reporting any issues. This continuous loop ensures that the BESS operates efficiently, responding dynamically to changing energy demands.
