中文摘要：

为实现对电网每日运行结果的评价,提出一套针对电网每日运行的评价指标体系,并讨论了相应的综合评价方法。首先,基于评价指标体系构建的一般原则和方法,设计了综合考虑电网运行在安全性、经济性、公平性和环保性4个方面需求的三级指标体系,该指标体系规模适中且能全面反映电网当日的调度运行情况。其次,在指标综合方法方面,考虑电网运行人员调度决策的需求,选用层次分析法确定各个指标的权重,应用逼近于理想解的排序方法进行指标综合,对指标综合方法的实际应用环节进行了讨论。算例分析结果表明,文中提出的方法可以自下而上实现对电网每日运行结果的综合量化评价,方便电网运行人员实现对不同日运行结果的纵向比较,可以为电网的优化运行提供指导。

英文摘要：

In order to assess the power grid＇s daily operation result, an assessment index systena for power grid＇s daily operation is proposed and the assessment method is discussed in this paper. Firstly, based on general construction principles of an assessment index system, a three-level assessment index system is designed in consideration of the power grid＇s operation needs in aspects of security, economy, equity and environmental fiiendliness. This medium-sized index system can fully reflect the power grid＇s daily operation. As for index integration, Analytic Hierarchy Process （AHP） is used to determine the weight of each index, and Technique for Order Preference by Similarity to Ideal Solution （TOPSIS） is used to integrate the index in consideration of the real needs of the operators, and the practical steps of this method are also discussed. Case study results show that the proposed method can evaluate the power grid＇s daily operation. This assessment system can be used for comparison of the power grid＇s daily operation results, and provide guidance for optimal operation of power grids.
