Reverse power flow in a low-voltage (LV) network can cause instability, such as in the line sections and distribution transformers [19, 20]. The overloading of the distribution transformer is one consequence of a low-load, high-PV penetration network; higher voltages are also seen at low-voltage (LV) and medium-voltage (MV) levels. [21, 22].
The next-generation PV inverters are intended to provide a variety of new control features (e.g.; voltage regulation, power curtailment, ramp-rate control, and communication-assisted protection) to enhance the interaction between utility-scale PV-DG plants and the grid.

The reverse power flow phenomenon occurs when the PV power generation in a grid-connected network exceeds the local load demand . This is an indication that RPF is more likely to occur in network regions with lower peak loads. Likewise, the overgeneration of PV solar production may lead to the appearance of RPFs in low-voltage networks [7, 18].
