Pbkp_redicting the Impact of Increasing Plug-in Electric Vehicle Loading on Bulk Transmission Systems

Abstract:

This paper proposes a methodology to assess the impact of the increasing penetration of plug-in electric vehicles (PEV) in cascading failures. Our methodology captures the stochastic nature of the charging profiles of PEV and presents an algorithm to generate a PEV charge profile. A pseudo-inverse based cascading failure model and the linearized (DC) power flow equations are used in the framework of a Monte Carlo simulation. Finally, we validate the proposed methodology in the New England IEEE-39 bus test system under different levels of PEV penetration. The results of this paper provide insights to plan the expansion of transmission systems as well as to develop countermeasures to mitigate cascading failures caused by the rising penetration of PEV charging stations.
