Abstract: For restoring the power system fast, reasonable selection of black-start schemes is very important. For recent years, scholars have proposed lots of black-start decision making methods. However, they are not able to compare their methods with the existing methods, and to reveal that their methods perform better. In this article, based on Mean Absolute Error, we propose a comparison strategy between black-start decision making methods, and make the quantitative analysis between different methods possible. Experiments are carried out on the data of black-start path of Guangdong power grid. We compare some commonly used weight determination methods and ranking methods. The results show that the black-start decision making method based on standard deviation weight and TOPSIS is superior to the other methods. The main contributions of this article are as follows: (1)A novel comparison strategy is proposed, all black-start decision making methods can be compared according to this strategy. (2)An optimal black-start decision making method is determined, which provides a evaluation standard for other scholars of black-start decision making.
