If we liken the energy storage system to the human body, EMS acts as the brain, determining the tasks performed, establishing reasonable work and rest patterns, and enabling self-protection in case of accidents. Different demands exist for EMS in source-grid side energy storage and industrial and commercial energy storage:
Alongside those, the EMS is also designed to offer lower latency in responding to grid signals, in other words boosting an already split-second response times, which Ruchira Shah says is going to be vital for asset owners looking to participate in increasingly sophisticated classes of ancillary and system stability services applications.
