[Abstract]:In order to meet the need of real-time scheduling of hydropower plants, a real-time optimal scheduling model of runoff hydropower plants is constructed, which aims at the maximum power generation. A real-time optimal scheduling system for hydropower plants with runoff is developed by using discrete dynamic programming (DDP) to approach the optimal calculation step by step. The system can predict the incoming flow process in the next 24 hours, and can be used to calculate the optimal generation operation process in 24 hours in the coming 24 hours, which can be used to quantitatively guide the real-time optimal dispatching of hydropower plants. Through the application of 6 runoff hydropower plants, the calculation accuracy of input discharge is over 98%, and the average annual power generation can be optimized by 45 million k W h..
