At: EUPVSEC - European PV Solar Energy Conference and Exhibition ; Amsterdam ; 25.9.2017 - 29.9.2017 ; Nowadays in Europe, the production from variable renewable energy sources (vRES) have seen a significant growth and the photovoltaic (PV) generation have played a central role. The proliferation of PV generators in different points of the distribution grid have caused different kind of disturbances that might compromise the correct operation and reliability of the grid. In particular, the overvoltage caused by PV generation limits the amount of PV that can be installed in a certain node of a distribution system. Related to this aspect the aim of this work is twofold. First, the hosting capacity of a specific distribution network is analysed based on voltage buses, current branch and power at transformer level. Then a suboptimal PV placement algorithm is proposed in order to reduce the overvoltage effect mitigating the issues related to a limited hosting capacity.
