EMS/SCADA Architecture for Energy Storage System

This document outlines the EMS/SCADA architecture for a large-scale energy storage system divided into four zones. Zones 1 to 3 each contain eight converter-boost integrated units, while Zone 4 has six. The system employs redundant data servers (A and B) at the station control layer, connected via station control layer switches to front servers and data network switches. Coordination control devices manage the overall system. Each zone features local control network switches (A and B) and data aggregation switches (A and B), placed in power communication cabinets at specific PCS locations (4#, 11#, 19#, 27#) to minimize convergence distance. Communication between aggregation switches and the station control layer uses gigabit optical ports (single mode), while PCS units use 100M electrical ports. The system supports IEC 61850 protocols, including GOOSE and MMS, for real-time control and monitoring. Each converter boost unit integrates BMS, EMU, and auxiliary systems (fire, liquid cooling, temperature, humidity, water immersion, access control) communicating via RS485 and IO interfaces. Battery compartments are numbered per zone, with detailed network and control switch placement referenced in the energy equipment numbering chart.
