Increased Renewable Hosting Capacity of a Real Low-Voltage Grid Based on Continuous Measurements : Results from an Actual PV Connection Request
In Communications in Computer and Information Science, 2021
Abstract
The distributed generation and new load patterns caused by the energy transition put strong requirements on the distribution grids. The traditional worst-case planning approaches in the low-voltage grid will lead to excessive grid extensions. In this paper, through a digital twin of the low-voltage grid, the true status of the physical grid is used to detect grid bottlenecks and therefore allows to match grid investments to actual needs in the distribution grid. This paper presents preliminary results from a real case study for the novel planning approach which lead to an accurate picture of grid hosting capacity, which is a major step forward from previously used worst case assumptions.
