基于权重自适应的电力应急预案指标评价方法

Evaluation method of power emergency plan index based on weight adaptive

针对传统电网灾变恢复预案评价的片面性问题以及传统的权重划分方法具有自身的局限性问题,提出了具有自适应权重特性的电力应急预案评价方法。具体介绍了在该方法中的全面性评价指标的构建和自适应权重的确定方法。以待评价电力应急预案和绝对正理想解的相似度最高为目标函数,以RC等级法的判断作为权重约束条件,通过计算比较各电力应急预案与绝对正理想解的相对贴近度大小,实现电力应急预案的优劣排序。该方法提高了评价指标的全面性,避免了人为主观因素对权重划分的影响。科学的预案评价结果为预案的制定与修改提供参考与辅助。最后的应用算例表明了该方法的有效性。

Aiming at the one-sided problem of traditional power grid disaster recovery plan evaluation and the limitation of traditional weight partition method,an evaluation method of electric power emergency plan with adaptive weights is proposed in this paper.The construction of comprehensive evaluation index and the determination method of adaptive weights are introduced in detail.With the highest similarity between the electric power emergency plan and the absolute positive ideal solution as the objective function and the judgment of RC grade method as the weight constraint condition,the relative closeness between the electric power emergency plan and the absolute positive ideal solution is calculated and compared to realize the ranking of the electric power emergency plan.This method improves the comprehensiveness of evaluation index and avoids the influence of subjective factors on weight division.The scientific evaluation results of plans provide reference and assistance for the formulation and modification of plans.The final application example in this paper shows the effectiveness of this method.
