【Abstract】Electric vehicle charging stations，as typical nonlinear loads connected to the distribution network， are prone to cause power quality problems such as harmonic polution and voltage fluctuations.This article constructs a thre-phase six-pulserectifiercircuit model，analyzes theload characteristicsand harmonic generation mechanismof the charging station，proposes theconceptof "harmonic phase Angledistributionentropy"，anddevelopsan improved particle swarm optimization algorithm to optimize the access strategy.The simulation resultsshow that the ordered access strategy can reduce the total harmonic distortion rate from 3.67% to 2.30% ， which can effectively improve the power quality.
