Plug-in hybrid electric vehicles as a demand dispatch option in a smart grid

Abstract

The increasing integration of Plug-in Hybrid Electric Vehicles (PHEVs) poses unique challenges for voltage and frequency regulation in electric distribution grids. PHEVs (Plug-in Hybrid Electric Vehicle) are at present the most reliable substitutes for normal fuel autos. The mobility and variability due to PHEV loads exacerbates the problem of voltage regulation in distribution grids that are characterized by high R/X ratios. Numerous studies have explored the impact of PHEV integration on distribution grids. This thesis examines the effect of different operations and impact of PHEV on the system having voltage sensitivity analysis and choosing an appropriate time of charging and discharging cycles. IEEE-34 node test feeder is used to charge the PHEV as required and discharge it when needed. Coding was done on the latest distributed system simulator for obtaining salient results to fulfil the goals. To inspect the proposed approach and evaluate its effectiveness and the performance of PHEVs, IEEE-34 Nodes Test Feeder network is used. The adopted platform to perform the desired methodology is Open Distribution System Simulator (DSS). The simulated results are emphasizing of voltage profile on most sensitive bus.
