Abstract :
Utilizing the power maximization model of short-term peak-load regulation, this paper analyzes the hydro-thermal joint peak-load regulation of power system based on multiple constraints such as the ramp-rate of thermal power units and water inflow of hydropower system. Then it presents several daily load segmentation methods with respect to different constraint conditions, and adopts engineering practical measures to prevent power volatility of thermal power units during the process of peak-load regulation. Finally, the effectiveness of this method has been tested and analyzed for hydro-thermal joint peak-load regulation of power system with multiple constraints through some examples.
