The increasing adoption of plug-in electric vehicles for commercial and consumer needs, coupled with government targets and incentives for use of renewable energy sources and reduction of greenhouse gases [1, pp. 44-45], has led to their consideration as power sources. Such vehicle-to-grid (V2G) systems seek to take advantage of the aggregate energy available within fleets of electric vehicles connected to power grids through bi-directional charging stations, by using them as distributed power sources for load leveling and peak shaving on the power grids . Unfortunately, V2G systems can introduce power quality issues, such as harmonics, with associated transients that pose a threat to the reliability and stability of traditional power grids .
This study examines the transient behavior of a test V2G system under varying vehicle and grid load conditions. The operation of a controlled bi-directional converter, in transient states related to voltage and load variance, is demonstrated using Simulink®. Estimation of network model component parameters is addressed. The resulting model is able to simulate the relationship between network transients and variations in grid loads under different operational scenarios, for potential application in the design and testing of V2G control and protection schemes.
