Power system considerations of plug-in hybrid electric vehicles based on a multi energy carrier model

A flexible modelling technique for Plug-In Hybrid Electric Vehicles (PHEV) based on a multi energy carrier approach is presented. It is able to simulate different PHEV architectures and energy management schemes while driving and during additional grid-coupled utilization modes. In contrary to the detailed vehicle models already available, the approach simplifies the vehicle but integrates possible services for the electricity network. Hence, the model offers analysis of the consequences for PHEVs from grid interactions. Contemporaneously, due to its simplicity and flexibility, the model can be easily facilitated to generate valuable inputs for power system analysis including vast amounts of PHEVs and paving the road for an integrated transportation and power system model. Results of load curves, availability of storage and ancillary power capacity are presented. As the model is based on the energy hub approach, an integration into multi energy carrier networks is intuitive and potential interactive repercussions from the systems can be studied.
