Study of the impact of DC distribution network under large-scale electric-powered vehicle access

Abstract As a high-standard verdant method of transportation, electric-powered-vehicles have become the development hotspot automotive business in recent years. Large scale access to electric-powered vehicles can form distributed energy storage system, which improve operational performance power grid peak shaving and frequency modulation, comprehensive utilization efficiency system energy. But at same time, large-scale connected DC distribution network will certain impact on its topology. Therefore, this paper studies location number topology establishes multi-dimensional evaluation The application result play an guidance role operation stability case vehicles.
