Original abstract
The rapid integration of renewable energy sources, particularly solar photovoltaic (PV) power plants, into modern electrical power systems has significantly affected the operation of distribution networks. The increasing number of prosumers has led to the emergence of reverse power flows, creating new challenges for voltage regulation, power quality, and transformer operation. Conventional distribution transformers and protection systems were originally designed for unidirectional power flow from generation sources to consumers. However, surplus electricity generated by PV systems is increasingly being injected back into the grid, causing voltage rise, increased power losses, and reduced equipment lifespan. This study proposes intelligent voltage control methods based on On-Load Tap Changer (OLTC) transformers to mitigate the adverse effects of reverse power flows. Mathematical modeling, artificial intelligence-based forecasting, and Smart Grid integration approaches are employed to enhance voltage regulation in distribution networks with high PV penetration.
