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].
Figure 5 characterises the transformer's active power flow per penetration, resulting from increased PV injection into the network. This shows a negative linear relationship between the active power operating load and the PV depth of penetration. The graph involves a sign change at the zero-crossing, beyond which reverse power flows.
power system as we know it, is shifting its dynamics to accommodate the renewable energy resources. The disrupting the traditional power flow to become bidirectional. penetration is referred as 'reverse power' flow. Due to the highly unpredictable nature of such variable
Similarly, in high PV penetration networks, the development of reverse power flow (RPF), which can cause transformer overload, has been reported to increase network load, overvoltage, and losses [14, 15, 16]. The reverse power flow phenomenon occurs when the PV power generation in a grid-connected network exceeds the local load demand .
