| Summary: | Due to rising environmental concerns and desire to achieve energy independence, the government of many countries across the world keen on promoting plug-in electric vehicles (PEVs). Consequently, high penetration of PEVs is expected in the imminent future. This work aims to develop models with the vehicle-to-grid operation of PEVs under different scheduling strategies namely, load stabilising model, charging/discharging cost model, battery degradation model and mixed-objective model, respectively. Further maximum penetration of PEVs corresponding to each scheduling model is evaluated. The impact of PEVs scheduling models on distribution system operational parameters such as peak load, transformer loading, distribution line limits and losses is also investigated. And finally, a comparative analysis of charging models in terms of technical and economic benefits is presented. The proposed model is implemented on the 38-node distribution system and simulation results demonstrate the comprehensive evaluation of proposed charging models.
