Project Background
The system adopts an outdoor cabinet integrated design, internally integrating a 215kWh/241kWh/261kWh single-cluster battery pack, 100kW/125kW 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.
Solution
The EMS realizes information collection, processing, cloud transmission, and third-party platform data forwarding for all equipment within the cabinet. It supports local control strategies such as peak-valley control, anti-backflow control, demand tracking control, PV-storage linkage control, and diesel generator linkage control. It supports peak-valley energy statistics and revenue statistics, with PV generation and battery charge/discharge statistics categorized by day, month, year, and total, along with Excel report export support.
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 EMS 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.
