The invention discloses a system and method for analyzing and determining the influence of a large-scale charging pile to a community distribution system. The system comprises a monitoring centre for analyzing and determining the influence of the large-scale charging pile to the community distribution system and a data acquiring terminal for acquiring the data of the charging pile, wherein the data acquiring terminal communicates with the charging pile by a network. According to the invention, the community distribution system capacity model, a normal distribution model of the community power load and power time, and charging real-time data are combined, so as to compare the calculated community distribution load curve with the distribution system capacity model, so that the operation condition of the community distribution system is monitored, a coordination scheduling policy for the community distribution system operation is determined and the permeability of the community electric vehicle is assessed. Moreover, the charging behaviours of the community electric vehicle are controlled in a coordinated manner, the influence of the community electric vehicle to the distribution system and the electric energy quality is reduced, the permeability of the community electric vehicle is improved, and the community distribution system is ensured to safely and stably operate.
