On the interdependence of intelligent charging approaches for plug-in electric vehicles in transmission and distribution networks

摘要

This paper proposes a novel approach to assess the impact of different plug-in electric vehicle charging strategies on power generation, transmission and distribution. The proposed impact assessment tool integrates simulations of transport behavior as well as power generation, transmission and distribution. The detailed temporal and spatial information of vehicle behavior obtained from the transport simulation is mapped to the transmission and distribution network models to perform a holistic assessment of the impact of different charging strategies. The charging strategies considered are uncontrolled charging and two types of smart charging schemes, one centralized the other decentralized. The advantage of this integrated approach is that both local and system-wide aspects can be analyzed simultaneously, uncovering effects that would otherwise remain unnoticed.
