Description

Technical Field

[0001] The utility model relates to the technical field of energy management system control, and in particular to an energy storage edge coordination controller. Background Art

[0002] The Energy Management System (EMS) is the "brain" of the energy storage system and the core of the coordinated control of the entire energy storage power station. It is an important tool and guarantee for achieving efficient, safe, stable and reliable operation of the energy storage power station and maximizing the use of renewable energy. The energy storage EMS energy management system coordination controller is mainly used to coordinate and control multiple PCSs to achieve advanced control functions such as joint operation, plan tracking, smoothing fluctuations, system peak regulation, rapid power tracking response, primary frequency regulation, peak shaving and valley filling, etc.

[0003] At present, the energy storage edge coordination controller refers to the coordination controller generally used in medium and large energy storage power stations on the power supply side or the grid side. The implementation forms of each EMS supplier are different. It can realize primary frequency modulation, AGC and other advanced control functions through high-performance PLC or embedded controller devices.

[0004] However, the coordinated control devices suitable for medium and large energy storage projects are expensive to use in industrial and commercial energy storage projects, with the main and standby redundant configuration costing about 150,000 to 200,000 yuan per set. In industrial and commercial energy storage projects, some EMS suppliers implement data acquisition, monitoring, storage and advanced control strategies by deploying them in industrial computers or servers. This method couples the monitoring system with real-time control instead of separating them independently, and the stability of the energy storage EMS energy management system has great safety and downtime risks. Some EMS suppliers achieve real-time control of energy storage systems through PLCs or embedded devices, but this method has fewer controller interfaces, requires module expansion during application, has too many devices, and may have compatibility issues between module matching.
