This paper investigates the power quality improvement on green energy source at generating side and grid side of power system. Now a day’s increasing the utility of power due to industrials and cultivations, such that problems also increases the sag, swell, real power, reactive power, transients and harmonics it will causes the disturbances in power system, to overcome this problems in this paper use the matrix and boost converter at one of the renewable energy generating side and unified power quality conditioner (UPQC) in grid system. The modeling and simulation with renewable energy sources connected one of the 50 bus system using unified power quality conditioner (UPQC).digital simulation using MATLAB/SIMULINK is done and the results are presented .The effect of UPQC on real power, reactive power, sag, swell, transients and harmonics is also presented.
