As the global demand for sustainable and environmentally friendly energy supply continues to increase, photovoltaic technology, as an important form of new energy, has received extensive attention. Photovoltaic grid-connected system is currently the most widely used form of photovoltaic power generation system. It converts direct current into alternating current and injects it into the grid to meet the power demand of users. However, the power grid imposes a series of requirements on grid-connected photovoltaic systems, one of which is the handling of harmonic problems. This article will focus on harmonic generation and how to perform THD (Total Harmonic Distortion) mitigation. As the key equipment of photovoltaic grid-connected system, inverter plays an important role in harmonic filtering. With a brief introduction to inverter-related THD. In this paper, by exploring how to optimize harmonic filtering to improve the performance and reliability of grid-connected photovoltaic systems, it is found that the method of suppressing THD by changing the PMW modulation is simple in calculation, easy to implement, and has high output waveform quality. And the method of suppressing THD by changing the equipment can reduce the harmonic quality.
