A systematic approach for analysing and improving operating conditions in distribution grids

Abstract

This paper presents a systematic approach for analysing and improving operating conditions in the distribution grids. It is based on collecting and processing data on the grid topology, grid elements, and their yearly loading profile. The data validation is performed by comparing the measured results with the grid model calculated ones. Afterwards, the grid model is applied to evaluate possible solutions for improving grid operation considering voltage profile and losses. These solutions include proper tap setting for individual transformers and the introduction of adequately sized and placed storage devices and reactive power compensators. The usage of the proposed methodology is demonstrated in the case of an actual distribution grid.
