With increased penetration of energy storage system in micro-grids, rapid and standardised information exchange is becoming essential for secure and reliable operation of energy storage system. This study presents an extensional information model for battery energy storage system (BESS) in micro-grid, which is based on the communication standards of the International Electrotechnical Commission (IEC) 61850. The implementation framework for BESS operation based on the extensional information model is proposed in detail; and the actual BESS operation tests are performed through an intelligent electronic device and a micro-grid test system. The experimental results show that the proposed BESS extensional information model and the implementation framework for BESS operation are available, which demonstrates an effective solution for flexible operation of BESS.
