    摘要:

    配电网损耗一直是供电企业考核的重要指标,配网线路复杂,分支多,精细化线损带来的成本效益计算困难。以配电网综合节能降损为目标,基于全时空节能要素特征,从时间、元件和费用维度建立全寿命周期内的全网成本指标和节能降损效益指标,并利用融合层次分析和基于交叉效率的数据包络分析的改进 VIKOR 方法对配电网综合节能效果进行评价,给出配电网综合节能降损的最优设计方案。最后,利用中国某地区配电网算例验证该文所提评价方法的可行性和有效性。

    Abstract:

    The line loss of distribution network is an important assessment evaluation index of electric power company. For complicated circuits and many branches of distribution network, it is difficult to calculate the cost and benefit brought by refining line losses. Under this background, aiming for the comprehensive energy conservation and loss reduction of distribution network, the life cycle cost and energy conservation and loss reduction benefit indexes are put forward from the aspects of time dimension, component dimension and expense dimension on the basis of the spatial-temporal elements of energy-saving features. The comprehensive energy conservation and loss reduction results are evaluated to derive the optimal design scheme of distribution network comprehensive energy conservation and loss reduction by the improved VIKOR method based on AHP and CEDEA analysis. Then the feasibility and validity of the proposed evaluation method are verified and validated by the actual distribution network in China.
