Simulation Analysis and Prospect of Charging Pile Access to Distribution Network Considering Power Quality Governance

With the rapid growth of the ownership of electric vehicles, the large-scale access of charging piles to the distribution network has brought significant impacts on power quality, and problems such as harmonic pollution and voltage fluctuation have become increasingly prominent. This paper analyzes the access modes of charging piles to the distribution network and explores their potential roles in power quality governance. Furthermore, harmonic analysis is carried out to evaluate the impact of charging piles on the power quality of the power grid. The feasibility of charging piles participating in power quality governance is verified through simulation. Finally, the multi-pile coordinated scheduling strategy is discussed to realize the friendly interaction between charging piles and the…
