Impact Analysis of Distribution Network Integrated Electric Vehicles Based on Monte Carlo Algorithm.

The significant integration of multivariate loads such as electric vehicles (EVs) has brought about notable changes in the structure and power flow distribution of traditional distribution networks. Therefore, in-depth research and analyze of the interaction scenarios between EVs and distribution networks are essential. In this study, a modeling and simulation of the load from EV charging stations was performed using the Monte Carlo algorithm. Subsequently, power flow calculations were performed on the IEEE 33-bus network to assess the influence of EV integration on both line losses and voltage deviations within the distribution network. The simulation results demonstrate that a substantial integration of EVs with distinctive load peaks results in increased line losses and compromises the voltage stability within the distribution network. Additionally, with a growing number of EVs, the influence on line losses and voltage deviations within the distribution network becomes increasingly significant.
