Integration of Large-Scale Photovoltaic system in the distribution grid under partially shading

Solar energy can play an important role when used in Large Scale Photovoltaic (LS-PV) system. The major drawback of the PV system is the efficiency of the energy conversion and the partially shading. This paper presents a study on the impact of the partially shading on the integration of LS-PV system of 1 MW in the grid, implemented in a multi-string topology.
