Distributed Generation (DG) can provide multiple benefits in MV/LV distribution networks. However, high penetration levels may cause technical issues to the grid, as already observed in some countries. Thus, Distribution Network Operators (DNOs) have to consider alternative solutions to guarantee normal operation, even under high penetration levels. In this paper, a time-series based probabilistic methodology is used to estimate the maximum PV hosting capacity of LV distribution networks. The proposed method is applied to assess a real rural Brazilian distribution system. According to the obtained results, voltage regulation and overloads in distribution transformers limit the PV hosting capacity. Therefore, aiming to increase this capacity, the use of PV VAr absorption and OLTC transformers was technically evaluated.
