Impacts of DG on Distribution Losses

This paper shows the results obtained in theanalysis of the impact of distributed generation (DG) ondistribution losses. The main objective has been to determine ifDG whether increments or decrements distribution losses, basedon the penetration level and dispersion of DG and on thedifferent DG technologies. Different scenarios with severalpenetration levels and dispersion of DG have been studied. Thespecial characteristics of different DG technologies have beentaken into account. The considered technologies are: combinedheat and power (CHP), wind turbines, photovoltaics and sometheoretical ones. Real radial distribution feeders have been used.
