Impact of PV distributed generation on EDP distribuição LV grid losses

Abstract

In this study, the authors detail the method used to build a set of low-voltage (LV) typical grids, which are able to capture the variability of assets and operating conditions in order to assess the non-linear impact of distributed generation on losses. Based on simulations carried out over such typical networks, the impact of photovoltaic (PV) distributed generation on LV grid losses is evaluated for (i) different PV penetration levels, up to 100% of secondary substation peak load, and (ii) for different PV geographic penetration scenarios, from urban to rural.
