【 摘 要 】

The integration of new energy sources will have a significant impact on the power quality of the power system. Solar photovoltaic power generation technology converts solar energy into direct current through photovoltaic modules, then converts the direct current into the same-frequency and in-phase sine wave current and enters the power grid through the grid-connected inverter. Inverter process will produce a large number of harmonics, resulting in harmonic pollution. Based on the statistics of harmonic measurement data of three typical PV loads, this paper analyzes the law of harmonics generated by photovoltaic power generation and studies its influence on the power grid.
