Abstract
The use of photovoltaic (PV) system for electricity generation is growing up in the last decades. The
southern part of Libya suffers from voltage fluctuation and intermittence of electricity during the
summer time. The aim of this paper is firstly to study and analysis a distribution grid of small village
located in the southern west region of Libya. We analyzed the existed 11KV distribution overhead
line supplied electricity of the village called Takarkibah using Power-World Simulator in order to
integrate it with PV plant. The results obtained show that injection of PV power about 70 % of the
grid power capacity gives good grid performance. After that, we use SAM simulation program to
design PV plant to improve the voltage profile in the distribution grid. Six designs (scenarios) are
simulated using different solar modules and inverters. The simulation results obtained from SAM
illustrated the power capacity, energy yield, and losses of the designed PV plant.
