Hosting capacity evaluation in networks with parameter uncertainties

Abstract

Nowadays, the maximum generation that can be hosted by distribution grids and how to increase it without violating technical constraints are main concerns of DSOs. In this paper, a novel model (named Bricks approach) is discussed, that is designed to estimate the hosting capacity of distribution grids even in case of uncertainties in grid parameters or lack of data. The proposed approach results particularly useful when it is not possible to collect all the necessary data for a classical load flow based analysis, as in the case of studies relevant to emerging countries electrification processes, or when data gathering is difficult, as in the case of complex modern distribution grids. In order to validate the approach, a real-life case study relevant to the Italian city of Aosta is presented.
