This simple procedure simulates an increasing power injection at every bus of the considered sample and checks the violation of operating limits in order to determine the maximum admissible nodal injection. The procedure is applied to a huge network data set, corresponding to real Italian MV grids and representing a significant subset (6%) of the system. Results presented in this paper could be a robust and statistically significant background for technical and economic considerations about the limits for penetration of dispersed generation in the Italian system.
