Distributed photovoltaic generators (DPGs) have been integrated into the medium/low voltage distribution network widely. Due to the randomness and fluctuation of DPG, however, the distribution and direction of power flow are changed frequently on some days. Therefore, more attention is needed to ensure the safe operation of the …
