This paper reports on a study, performed on a significant sample of Italian MV networks, aimed at the estimating the benefits deriving from the application of different limits (in terms of power factor to be respected by MV and LV final customers). The benefits obtained are evaluated w.r.t. network real losses and to power quality (in particular, supply voltage variations). Finally, a cost/benefit...
This paper describes a procedure developed by the authors with the aim to evaluate the capability of Medium Voltage (MV) busses to accept power injection from dispersed generators and to support the distribution system operators in facing the growing penetration of dispersed generation, especially due to Renewable Energy Sources (RES).
The procedure developed by the authors simulates an increasing power injection at every bus of the considered sample and checks the violation of operating limits (current, SVV, RVC) 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 (7%) of the system.
