黑启动决策中指标值和指标权重的灵敏度分析

黑启动决策的优化对电力系统在大停电后的快速恢复具有重要作用。为了适当选择决策指 标中的指标值和权重，有必要分析决策结果对这些参数的灵敏度，迄今未见有关的研究报道。文中 在介绍简单加权法决策模型的基础上，提出了一种灵敏度分析方法，研究了指标值和指标权重的变 化对黑启动优选方案排序的影响，得到导致排序结果变化的灵敏度临界值。该灵敏度分析结果有 助于调度人员选择黑启动方案，并按照实际恢复过程中相关因素的变化，采取有效应对措施。通过 算例验证了该方法。

Sensitivity Analysis on the Values and Weights of Indices in Power System Black-start Decision-making

Determining the optimal black-start restoration strategy is one of the most important issues having impacts on the restoring speed of a power system after a blackout.However,some parameters employed in making the decision such as values and weights of some indices are difficult to be quantified or their variable domains are large,and as a result how to properly handle these parameters or study the impacts of the variances of these parameters on the decision-making result is an important issue to be examined...
