Research on Evaluation Method of Distribution Network Loss Reduction Potential Based on Spatial Distance

Improving power utilization efficiency and reducing power losses can effectively support China’s “dual carbon” goals, but how to evaluate the power grid’s ability to reduce power losses is an issue that needs to be urgently addressed. A distribution network loss reduction potential evaluation method based on spatial distance is proposed in this paper. According to the electric energy efficiency standard, the distribution network loss reduction evaluation index is provided and further divided into extremely large and extremely small indexes. Each evaluation index is represented as a point in multi-dimensional space, and the distance between this point and the isocline of the multi-dimensional space is considered as the loss reduction potential value. The larger the value, the greater the loss reduction potential. An example analysis showed that this method can not only effectively evaluate the loss reduction potential of different loss reduction schemes for a single distribution network but can also be used to evaluate the loss reduction potential of multiple distribution networks.
