What is energy management system architecture?Energy Management System Architecture Overview Figure 1 shows a typical energy management architecture where the global/central EMS manages multiple energy storage systems (ESSs), while interfacing with the markets, utilities, and customers .
What are energy management systems (EMS)?Energy Management Systems (EMS) play an increasingly vital role in modern power systems, especially as energy storage solutions and distributed resources continue to expand.
What is a highly centralized energy management system architecture?In a highly centralized architecture, the optimal dispatches (i.e., power commands) are calculated at the control center and sent to each local EMS. In a highly decentralized architecture, the central EMS may not exist, therefore, EMS functions are only performed at the local EMSs. Figure 2. Energy Management System Hierarchy Architecture 1
