摘要: |
选取合理的黑启动模式有利于评选最优黑启动方案。分析了黑启动策略、模式和黑启动方案的配合,研究了黑启动模式的约束条件和各种模式的特征。在分析黑启动模式综合评价指标选取原则基础上,提取了黑启动模式的综合评估指标体系并进行层次化处理。对层次化的评估指标体系,指标层利用主成分分析法消除了指标间的关联,准则层利用客观性很强的熵值法给出各模式的最终评价值,最后分析了评估方法的灵敏度。实际算例证明了此方法的有效性和可行性,能够为调度人员选取最优黑启动模式提供参考。 |

Abstract: |
Selecting a reasonable black-start mode is helpful to decide the optimal black-start scheme. This paper analyses the cooperation of black-start strategies, black-start modes and black-start schemes, and then studies the constraint conditions and characteristics of black-start modes. Based on analyzing the selection principle of the black-start mode comprehensive assessment index system, it extracts the system and handles it with hierarchical processing. In the hierarchical assessment index system, principal component analysis is used to remove the correlation between the indexes in the index layer, and entropy value method is used to obtain the ultimate evaluation value in the criterion layer. At last, it analyses the sensitivity of the method. A practical example proves its effectiveness and feasibility. This method is able to provide a reference for the schedulers to choose the optimal mode. |
