Abstract


  • A high penetration of one-phase rooftop solar photovoltaic

    (PV) units with unbalanced allocation can create considerable

    neutral current and neutral potential rise in low voltage

    (LV) four-wire multigrounded distribution networks, even with

    balanced loads. Because of the limitations of traditional strategies

    to mitigate the combined effect of load and PV unbalance,

    this paper proposes the use of distributed energy storage to reduce

    the neutral current and neutral potential under a high penetration

    of unbalanced rooftop solar PV allocation. A power-balancing

    algorithm based on charge/discharge control is developed to continuously

    adjust the power exchange with the grid to mitigate the

    neutral current and neutral potential rise, while minimizing power

    drawn from the energy storage. A dynamic model of the integrated

    PV-storage system is developed to investigate the dynamic

    performance of the proposed strategy. An Australian LV distribution

    system is used to verify its performance and the results are

    presented
