Grid Stability and Cybersecurity Challenges in Electric Vehicle Integration: A Case Study of the ERCOT System

Abstract

With the growing popularity of EVs in Texas, ERCOT faces the challenges of accommodating the increasing demand for electricity from these vehicles while maintaining system security. This paper aims to investigate the impact of electric vehicle (EV) charging on the stability and cybersecurity of the ERCOT grid. Utilizing ERCOT’s industry level PSSE model, this paper examines the thresholds of simultaneous EV charging that the system can sustain safely. Besides, it highlights cybersecurity vulnerabilities introduced by EV charging infrastructure.
