The determination of the optimal black-start strategy has significant impacts on the speed of power system restoration after a blackout. In the existing black-start decision-making methods, the employed indexes cannot be well synthesized, and the relevance among the indexes cannot be taken into account. Given this background, the Vague set is first employed in this work to represent the indexes for facilitating the comparisons among them. Then, the Vague value measure is presented, and a mathematical model for black-start decision-making is developed. Compared with the existing methods, the developed method could deal with the relevance among the indexes and more reasonably represent the fuzzy information. Finally, an actual example is served for demonstrating the essential features of the developed model and method.
