Abstract
In this study, a mathematical model was developed to describe the charging process of a charging pile. The PWM charging process was determined, and a mathematical model for the DC-DC output of the charging pile was constructed. Prior to the photovoltaic connection, the voltage distribution of the distribution network was determined, and the line voltage drop was obtained. The impact of the access capacity of distributed charging piles on the voltage of the distribution network was analyzed. Furthermore, the line voltage drop between nodes was determined, and the nodes were balanced to calculate the voltage of each node at this time. This analysis enabled the investigation of the impact of distributed charging pile access on the voltage deviation of the distribution network. The results indicate that the calculation error of voltage deviation in the distribution network is only 0.002, with a maximum prediction accuracy of 99.0%.
