تاثیر وسیله نقلیه الکتریکی پلاگین و تولید توزیع شده بر قابلیت اطمینان سیستم های توزیع

The use of Plug-in electric vehicles (PEV) are increasing in recent years because of its environmental friendly nature over the conventional vehicles. In the upcoming years, the use of PEVs will increase significantly. The connection of PEVs to the distribution system will lead to the new challenges. This paper evaluates the impact of PEV connection on system reliability. Studies are carried out for different PEV penetration levels to analyze the impact. Some PEVs are operated in vehicle to grid (V2G) mode to support the system peak loads. Distributed generation (DG) units are integrated with charging stations to reduce the PEVs charging impact on the system. In the present study, charging stations are integrated with solar PV units which magnifies the intention of PEV usage. Along with the system reliability evaluation, Expected Energy Not Charged (EENC) is proposed to measure the reliability of the PEVs in the system. The combined effects of PEV charging and DGs are also studied. The impact assessment is done for two practical systems.
