Domestic and Foreign Policies Regulations and Technical Standards of Distributed Photovoltaic Difference Analysis in Power Quality

Under the trend of global energy transformation, photovoltaic has become the fastest growing track in new energy. In view of the situation that policies and standards of distributed photovoltaic power generation need to be improved, this paper focuses on the comparative analysis of power quality related policies and standards in Germany and the United States , and puts forward countermeasures to the differences in China that in order to provide more scientific, safe and advanced help for the power quality management of distributed photovoltaic grid-connected.
