摘 要: 提出了反映电网结构是否适于调度权下放的一些指标,在此基础上运用层次分析法和熵权决策理论对电网结构进行综合评价。用层次分析法确定各指标的主观权重,用熵权法得到客观权重,将主观和客观评价相结合,通过实际算例分析,对可靠性和安全性指标进行评价,将可靠性和安全性指标的偏离度作为上一级指标的数据进行最后的综合评价。该方法可指导电力系统调度运行,从而有效地减少调度员的操作量,提高调度工作效率。

Abstract: Some indices were raised to reflect the suitability of power grid structure for the dispatching right devolution. On the basis of this, the analytic hierarchy process (AHP) and entropy weight decision-making theory were used to comprehensively assess the power grid structure. The AHP was employed to determine the subjective weights, while the entropy weight used for attaining the objective weights. The subjective assessment was combined with the objective assessment. Via the practical example analysis, the reliability and safety indices were carried out assessment, and the offset degree of reliability and safety indices was taken as the data of indices at the next higher level to carry out final, comprehensive assessment. This method can guide the operation of power system dispatching to reduce workload of dispatchers effectively and to improve efficiency of dispatching.
Key words: dispatching right; power grid structure; analytical hierarchy process; entropy weight; entropy weight decision-making theory
