摘要

Abstract

This paper investigates the impacts of large-scale electric vehicle (EV) grid integration on power system stability

focusing on voltage

frequency

and oscillatory dynamics. With the increasing penetration of EVs driven by low-carbon transition policies

their uncertain and clustered charging behaviors introduce potential risks to traditional power grids. Through mathematical modeling

simulation

and experimental validation

this work identifies the mechanisms by which EVs affect voltage fluctuations

frequency deviations

and oscillation modes. Optimized charging/discharging strategies

including vehicle-to-grid (V2G) participation

are proposed to mitigate instability. The results demonstrate that coordinated EV scheduling can significantly enhance grid resilience and enable efficient renewable energy integration. This study provides theoretical and practical insights for future smart grid planning under high EV penetration scenarios.
