Effect of the PV/FC hybrid power generation system on total line loss in distribution network

In this paper, the effect of PV/FC hybrid power generation system on total line loss of distribution network has been studied. Studies have been conducted on a real life 20 kV distribution network. A DPL (DIgSILENT Programming Language) code is developed to analyze the effect of the PV/FC hybrid system on total line loss in distribution network. Simulations, in three loading conditions and by considering worst environmental conditions (cloudy weather, at nights, etc) that output power of PV system is zero have been done. Sample distribution network has been considered in two structures: 1-sample distribution network by PV system as DG and 2-same distribution network but by PV/FC hybrid power system as DG. The Simulation results illustrate the effectiveness of PV/FC hybrid system in order to decrease the total line loss.
