Outdoor Multi-Cabinet Parallel Energy Storage System
Multiple single cabinets operate in parallel with a central coordinating controller achieving a combined centralized and independent control strategy; single cabinet faults are automatically isolated, supporting station-level comprehensive data statistics.
01 Project Background
The system uses multiple single cabinets operating in parallel, with each outdoor cabinet internally integrating a 215kWh single-cluster battery pack, 100kW grid-forming PCS, BMS (three-level or two-level architecture), STS (automatic on/off-grid switching device), air-cooled or liquid-cooled air conditioning, metering meters, and other environmental sensors, along with an integrated 4G wireless camera.
02 Solution
The EMS uses a central coordinating controller to achieve multi-cabinet parallel control, combining centralized and independent strategies. When a single cabinet fails, the system can automatically isolate it from other cabinets without affecting their operation. Statistics include both detailed data for individual cabinets and comprehensive data for the overall project.
03 Project Results
The EMS system supports remote unattended operation with local execution of power control strategies, ensuring system operation is unaffected even if the remote network fails. The edge controller and cloud independently store system operation data, allowing local records to be retrieved for fault tracing in case of network failure. EMS operation strategies can be remotely modified anytime and anywhere via web or mobile app, and essential system operation parameters can be opened to users for self-maintenance.
