Error analysis and believable bound selection of line loss comparison in the distribution grid

The line loss control project is important task for energy conservation and loss reduction. The loss comparison of special lines in the distribution grid is an important part of this project. In this paper, the errors in the line loss comparison work are analyzed in detail based upon the actual working experience. A new method of believable bound selection for special line loss comparison work is introduced, and the example shows the accuracy of the method.
