Using measurements to increase the accuracy of hosting capacity calculations

Abstract

This study has compared five different methods for calculating the hosting capacity in a distribution grid. The results show a large difference in the obtained hosting capacity depending on the method used. It was found that the use of measurements in the calculations greatly increases the hosting capacity, compared with when using assumptions based on a ‘worst case scenario’, without increasing the risk for the network operator or other customers. It was also found that the statistical index used (i.e. 100, 99, or 95%) has a large impact on the calculated hosting capacity.
