The access rate of electric vehicles and distributed photovoltaics in the distribution network was increased year by year,but the randomness of their power would brought great influence to the voltage regulation of distribution network.Based on the analysis of the power characteristics and reactive power regulation ability of electric vehicles and distributed photovoltaic,the influence principle of electric vehicle and photovoltaic grid connection on the voltage of distribution network were studied,and the voltage active regulation model considering both EV and PV reactive power regulation capability was established,the voltage adjustment amount of the next time was calculated according to the predicted load and the predicted power of photovol-taic and electric vehicles,and select the mean of voltage regulating according to the order of economic sensitivity.A simulation example of voltage regulation in distribution network with electric vehicle accessed was established,and through the effect of pressure regulation of the voltage regulation strategy,the superiority of the voltage regulation strategy in this paper is verified.
