Electric Vehicle Interaction at the Electrical Circuit Level

项目名称：	Electric Vehicle Interaction at the Electrical Circuit Level
摘要：	This project evaluated the impacts of electric vehicles (EVs) on the electricity distribution grid. After conducting a literature review on the current state of EV charger technology and on over-voltage mitigation, a transient time domain model of a sub-circuit service area has been developed. This model integrates EV charging and PV load generation into the utility grid and utilizes EV charging as a means of mitigating transient over-voltages (TOVs) in various scenarios. A novel methodology for early detection of TOVs demonstrates that the technical topology of the charging station combined with the connected load of the EV can be used to prevent and eliminate over-voltage peaks. This effect can then be used to improve the response time and reliability of inverter-based islanding detection and, thus, increase grid reliability. The proposed over-voltage detection and prevention methodology is currently being verified for practicability with measured residential data sets. The project results are presented in three published reports. Continuing work involves collecting residential data to understand load variability and disaggregation of load.
