Adequacy evaluation of residential distribution network with PHEVs penetration

Plug-in Hybrid Electric Vehicles (PHEVs) are emerging as a new form of distributed energy resources for power grid, and their charging/discharging patterns will inevitably affect the power system reliability. This paper is concerned about the system adequacy after integrating PHEVs into residential distribution systems. To truly reflect the impact of PHEVs charging, a conditions-dependent outage model is applied to calculate the change of probability distribution function (PDF) for the power transformer. A time sequential Monte Carlo simulation is utilized to obtain the reliability indices in system adequacy evaluation. The IEEE-34 feeder system is used to represent the residential distribution system in case studies, and simulation results are presented and discussed.
