The EMS system serves as the nervous center and energy management hub of a energy storage power station, providing comprehensive information sensing on the operation of various types of equipment, environmental conditions, and personnel management within the station. It monitors operational data from BMS, PCS, air conditioning systems, fire protection systems, and more, and integrates functions such as power generation and energy storage monitoring, as well as power supply monitoring. At the same time, the EMS system can also integrate microgrid system power generation, PCS control, load management, and other related functions. It enables both planned operation modes and dispatch-based operation modes, and based on real-time data from battery packs, PCS, photovoltaic systems, or wind turbines, it can rationally allocate and adjust control commands accordingly.

The RE-7900 Energy Management System (EMS) is a next-generation energy management system platform that has been newly designed to meet current and future trends in the energy storage industry, building on the solid foundation of the integrated automation systems that have been stably operating at new-energy power stations with capacities exceeding 10 GW.

The system’s real-time database supports open-source MySQL, domestically developed Dameng, or RenDa JinCang; the historical database uses a time-series database that can handle up to one million records per second on a single server and offers millisecond-level query latency. The platform has been carefully designed with a layered architecture of “platform plus application,” featuring robust cross-platform capabilities. It is compatible with a wide range of hardware platforms (servers, workstations, industrial PCs, microcomputers, etc.) and can run on various operating systems (Windows, Linux, Unix, China’s Beijing Ningsi, Kylin, and others), fully meeting the diverse operational environment requirements of Energy Management Systems (EMS).

The system’s design adheres to international standards such as IEC61850 and IEC61970, and adopts the most advanced and widely used C/S master-slave distributed architecture. The supporting software integrates a variety of high-level applications, including a network data transmission soft bus, a reporting subsystem, an access control subsystem, an alarm service, general services, a human-machine interface subsystem, a graphics subsystem, and a data acquisition subsystem. The system features seamless connectivity with devices compliant with protocols such as IEC61850 (MMS, GOOSE), IEC104, and IEC103. It provides comprehensive and mature solutions for energy storage management systems of all sizes.
