摘要

配电系统（DS）的可靠性对客户服务的可用性影响最大。提高系统的可靠性水平是一项耗资巨大的任务，因此确定一个高效、经济的可靠性指标目标水平具有重要意义。为了实现这一目标，本文提出了一种基于数据包络分析（DEA）的综合方法。DBM在将常规平均法作为其步骤之一的基础上，综合考虑了技术因素对可靠性指标水平目标确定过程的影响。通过引入可靠性成本曲线，DBM能够根据系统投资的实际效果来设定可靠性目标。此外，该特性还可以估算满足目标所需的额外投资。结果表明，该方法在经济上优于传统的平均方法，并显示了将技术因素纳入该方法的价值。所确定的可靠性目标至少比具有高可靠性值的馈线成本效益高2.85 %。由于其一般特征，所提出的方法可以应用于其他工程系统的基准测试，其中类似的单元正在运行，并且可以建立单元输入和输出之间的关系。

Data envelopment analysis to determine reliability targets for power distribution systems

Distribution system (DS) reliability has the greatest impact on customer service availability. Enhancing the reliability level of a DS is a costly task, thus, determining an efficient and economical target levels for reliability indices is of high importance. To achieve this goal, this paper proposes a comprehensive Data Envelopment Analysis (DEA) based method (DBM). DBM integrates the effect of technical factors in the target determination process for the level of reliability indices in addition to including the conventional average method as one of its steps. By introducing a reliability–cost curve, DBM becomes capable of setting reliability targets based on the practical effect of investment in the system. Furthermore, this feature enables the estimation of the additional investment required to meet the targets. The results indicate the superiority of the proposed method in comparison with the conventional average method from the economic aspect and show the value of integrating the technical factors into it. The determined reliability targets are at least 2.85 % more cost-efficient and technically sounder for the feeders with a high value of reliability. The proposed method, due to its general features, can be applied in the benchmarking of other engineering systems where similar units are being operated and a relation between the unit’s inputs and outputs can be established.

期刊介绍： Applied Energy serves as a platform for sharing innovations, research, development, and demonstrations in energy conversion, conservation, and sustainable energy systems. The journal covers topics such as optimal energy resource use, environmental pollutant mitigation, and energy process analysis. It welcomes original papers, review articles, technical notes, and letters to the editor. Authors are encouraged to submit manuscripts that bridge the gap between research, development, and implementation. The journal addresses a wide spectrum of topics, including fossil and renewable energy technologies, energy economics, and environmental impacts. Applied Energy also explores modeling and forecasting, conservation strategies, and the social and economic implications of energy policies, including climate change mitigation. It is complemented by the open-access journal Advances in Applied Energy.
