The Impact of Harmonic Generated by Distributed Photovoltaic Grid-connected Power Generation System

Since the industrial revolution, the application of traditional petrochemical energy has brought a lot of pollution and greenhouse effect to the global environment, and new energy technology, as one of the important ways to solve global environmental problems, has been widely recognized by all countries in the world, and its application has become more and more deep widely. As a majority of distributed photovoltaic projects are integrated into the distribution network to generate electricity, the impact on the distribution network and system stability has become increasingly prominent. Since distributed photovoltaic grid connection is the main form and development trend of photovoltaic power generation in the future, analyzing the impact of its harmonics on the distribution network is particularly important for maintaining the stable operation of the grid system.
