In this paper,combining with current situation of regional power distribution network and the typical pattern and its operating characteristics of photovoltaic power integration,the impact of photovoltaic power on voltage fluctuations of distribution grid has been analyzed by the method of voltage fluctuations caused by power changing. Thus,the ability of regional power distribution network to accept photovoltaic power has been studied. The results show that the total capacity of the photovoltaic power integrated is related to its power factor. The smaller the average power factor,the smaller the permitted capacity to be integrated. The fiercer the fluctuation of output power,the higher the degree of uncertainty,which has a significant impact on the voltage stability of distribution network.
