摘 要: 提出了反映電網(wǎng)結(jié)構(gòu)是否適于調(diào)度權(quán)下放的一些指標,在此基礎(chǔ)上運用層次分析法和熵權(quán)決策理論對電網(wǎng)結(jié)構(gòu)進行綜合評價。用層次分析法確定各指標的主觀權(quán)重,用熵權(quán)法得到客觀權(quán)重,將主觀和客觀評價相結(jié)合,通過實際算例分析,對可靠性和安全性指標進行評價,將可靠性和安全性指標的偏離度作為上一級指標的數(shù)據(jù)進行最后的綜合評價。該方法可指導(dǎo)電力系統(tǒng)調(diào)度運行,從而有效地減少調(diào)度員的操作量,提高調(diào)度工作效率。
關(guān)鍵詞: 調(diào)度權(quán);電網(wǎng)結(jié)構(gòu);層次分析法;熵權(quán);熵權(quán)決策理論

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
