System introduction
Industrial and commercial energy storage system is a system that can store electric energy and supply power, with smooth transition, peak shaving and valley filling, frequency and voltage regulation and other functions. It can smooth the output of solar and wind power generation, and reduce the impact of its randomness, gap and fluctuation on the power grid and users; Charging in the valley price period and discharging in the peak price period can reduce the user's electricity expense; In case of power failure in the large power grid, it can operate independently to ensure uninterrupted power supply to users.

Energy management system(EMS)
In the energy storage system, the EMS communication topology is divided into two layers. The top layer is the general centralized monitoring system.
Bottom equipment: energy storage converter, battery management system (BMS), environmental monitoring equipment, fire protection system, air conditioning or access control system, etc. are all connected to the monitoring system (currently with administrator authority management, soft access control).
The monitoring host completes the network connection, conversion, data acquisition, data local processing, protocol conversion and command exchange between the on-site monitoring and control systems, local user screen monitoring operation, control strategy, and WEB server functions, and realizes the high-speed collection and transmission of large-capacity real-time data, so as to ensure that the master station system can quickly and accurately obtain all monitoring and monitoring information, and timely feed back the system abnormalities and faults detected by the network, Ensure fast positioning and recovery. (It needs to be realized through station-level BMS)
