Abstract: In order to accurately calculate the abandoned water power and peak shaving abandoned water power of hydropower stations,and ensure that the hydropower station power generation plan made during period of abandoning water is reasonable and fair,the causes and composition of abandoned water power were analyzed. We proposed that the virtual electricity generated by the blocked output did not belong to the abandoned water power. According to the category of abandoned water,a new method for calculating different types of abandoned water power was proposed,and the peak shaving abandoned water power was calculated by using the“integration-separation”mode. The daily regulation and annual regulation hydropower stations were selected to carry out results verification. The results showed that due to avoiding the statistics of hindered abandoned water power and the nesting of different types of abandoned water power,the new calculation method on abandoned water power and peak shaving abandoned water power were more in line with the reality,and the results were more accurate than the traditional method; the calculation formula had unified form,which could adapt to the hydropower stations with different regulation performance,and further simplified the calculation process.

Key words: abandoned water power; peak shaving abandoned water power; expected output; blocked output;
