Research On Active Power Control Of Photovoltaic Power Generation System

Resources are increasingly nervous around the world,the increasingly high demands for power quality are also raised be more and more power users,the global power industry faces unprecedented challenges.To meet these challenges,the global power industry are focusing on developing distributed generation(DG)and smart grid And this is also China’s "Twelfth Five-year" major construction project planning.This article introducecd the basic concept and application of smart grid and DG,and then analyzed the impact of DG to smart grid from the influence on power flow and relay protection setting value.And then combined with the "Twelfth Five-year"of social development planning,concerned with the develop project of smart grid in Beidaihe new area,this article probes into the new clean energy access scheme of intelligent distribution network.Based on the status of Beidaihe new area,three kinds of typical DGs,ie.landscape wind turbines,photovoltaic power station and wind farms,are mainly studied in this project.At the end of the article,the access scheme of DG for the intelligent distribution network at Beidaihe district were proposed.
