4.2 Effect of PV MPPT with DC bus control methods on power quality. Because the input power of PV system has been changing, there will be large DC voltage fluctuation on the DC bus, which leads to the MPPT method of PV system cannot better track the maximum power point. Lead to a large amount of power waste and power quality decline.
