Integration of Plug-In Hybrid Electric Vehicles into energy networks

Electrification of substantial percentages of individual transportation through Plug-In Hybrid Electric Vehicles (PHEVs) will lead to an integration of power and transport systems. This, in turn, will impose an additional demand on today's power system, potentially stressing hazardous for some pieces of equipment. Smart management schemes, investigated in this paper, can alleviate possible congestion issues in power systems by intelligently distributing available energy among connected PHEVs, modelled as agents with individual parameters and goals. The management scheme is integrated in aggregation entities, clustering PHEVs in various urban areas. Network impacts resulting from the smart management scheme will be studied based on power flow calculations. The analysis will give implications for PHEV integration schemes as well as tentative ideas of possible repercussions on hybrid power systems and how to counteract.
