电力系统黑启动决策方法比较研究

黑启动作为电力体系安全防御和事故后快速恢复的措施之一,其路径的合理选择对电力系统快速恢复供电具有重要意义。近年来,学者们从不同角度提出了多种黑启动方案决策方法,然而并没有实现各决策方法间的优劣比较。本文引入平均绝对偏差公式,设计了一种黑启动决策方法比较策略,实现了黑启动决策方法的量化比较。在所提比较策略基础上,对常用的黑启动权重确定方法和排序方法进行了实验分析,广东电网上的实验结果表明基于标准差权重和TOPSIS排序的黑启动决策方法具有最高的准确性。本文的价值在于:(1)提出了一种新的比较策略,使黑启动决策方法的量化比较成为可能;(2)通过大量实验确定了一种优化的黑启动决策方法,为后续黑启动决策研究提供了比较基准。

Comparison of Black-start Decision Making Methods in the Power System Restoration

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.
