Effects of PEV penetration on voltage unbalance

Chapter


Abstract


  • Balancing loads in low voltage networks is a challenging task due to a

    continuous fluctuation in the power demand. Voltage unbalance is a condition in

    which the voltage phasors differ in amplitude and/or do not have its normal 120°

    phase relationship. This has a potential to introduce technical issues that lead to a

    costly phenomenon for power distribution system due to the high penetration of

    Plug-in Electric Vehicles (PEVs). Voltage unbalance study is essential as the propagation

    of zero sequence component in the distribution system is limited by transformer

    winding connections and network grounding. Indeed, single phase loads are

    not affected by unbalance unless the unbalance causes over or under voltages which

    exceed the acceptable limits. However, the large numbers of PEVs charging from

    single phase residential feeders of distribution networks may exceed the statutory

    limits. This chapter presents theoretical discussion with analytical framework for

    modeling the effects of voltage unbalances due to PEV penetration. A PEV charging

    profile of a conventional PEV battery has been employed with the daily load demand

    to synthesize the dynamic effect of PEV penetration. A distribution network topology

    has been used with unbalanced allocation of single-phase loads and PEVs connected

    in four-wire, three phase network to investigate the effects of PEV charging

    on the feeders subject to voltage unbalance. Furthermore, the chapter explores the

    application of PEV load balancing strategy in the context of smart grid to mitigate

    the effects of unbalanced allocation of PEVs.
