Impact of Distributed Generation on power losses on an actual distribution network

Distributed Generation (DG) operating in a distribution network influences active power losses. In this paper power losses have been estimated for an actual low voltage distribution network and compared for different situations according to the DG penetration and placement of the power units. A practical method to place new DGs is presented. The basic idea is to minimize power losses, while complying voltage network limits, calculated with power flows using historical data over a discrete number of possible points of connection.
