One of the primary concerns with this grid-connected PV system is overloading due to reverse power flow, which degrades the life of distribution transformers. This study investigates
Notably, battery energy storage systems (BESS) are utilised to demonstrate how transformer overloads may be minimised in the presence of high solar PV penetrations into the grid. Similarly, Ref. employed the BESS scheme in their study to prevent the progression of RPF in a real distribution network due to high PV penetration.
In low-voltage networks with high PV penetration; therefore, planners should consider transformer overload limits caused by reverse power flow, which degrades transformer life. This helps select control schemes near substation transformers to limit reverse power flow. 1. Introduction
The simulation studies' results provide useful information not only on the impact of RPF on distribution transformer loadings but also on the depth of penetration in a solar PV-integrated LV network. The study determines a set of safe margins to safeguard the flow of reverse power into the substation transformer.
Summary of transformer overload and backflow limits. Sustained and increased reverse power flow can result in transformer overload beyond its rated value . With solar PV injection, each distribution circuit should have a maximum capacity for accommodating distributed production.
