The Huadian Zhiyu-Wujiang Ruisuan model, China’s first large-scale river basin runoff forecasting model, has been put into operation, together with an integrated platform for the smart dispatching, decision-making, and operations of basin-wide hydropower, wind, and solar resources. The launch of the model ushered in a new chapter in China’s smart dispatch and use of hydropower.
The model represents a significant breakthrough made by China Huadian Corporation Ltd. (CHD) in runoff forecasting. The model enables artificial intelligence technology to be more compatible in hydropower operations and effectively addresses various challenges — it can enhance runoff forecasting accuracy and facilitate the coordination within a multi-energy system that incorporates hydropower, wind and solar resources.
Notably, the Huadian Zhiyu-Wujiang Ruisuan model is also China’s first large model that is used to forecast runoff in a large karst river basin. Compared with conventional models, it increases the accuracy by 5 percent on short-term flood forecasting as well as 15-day runoff forecasting, thereby offering a more solid basis for flood prevention and disaster mitigation, environmental protection and shipping.
CHD equips the model with a 50-TB, multi-source dataset, as well as a range of advanced technologies, such as deep learning-based rainfall-runoff coupling models. The model’s forecasting on 15-day runoff is over 85 percent accurate, maximizing clean energy consumption and power generation efficiency.
