In this work,we have considered the power-law correction of entropy on the horizon. If the flat FRW Universe is filled with the n components fluid with interactions,the GSL of thermodynamics for apparent and event horizons have been investigated for equilibrium and non-equilibrium cases. If we consider a small perturbation around the de Sitter spacetime,the general conditions of the validity of GSL have been found. Also if a phantom dominated Universe has a pole-like type scale factor,the validity of GSL has also been analyzed. Further we have obtained constraints on the power-law parameter α in the phantom and quintessence dominated regimes. Finally we obtain conditions under which GSL breaks down in a cosmological background.
