The large-scale integration of distributed photovoltaic (PV) systems into distribution networks has led to challenges in power supply safety, economic efficiency, and reliability. Among these issues, voltage quality anomalies in the distribution network are the most direct and pose significant barriers to the development of distributed PV. As power quality assessment requirements become increasingly stringent, it is essential to design reliable and effective technologies for addressing low-voltage distribution network anomalies. This study proposes an end-user voltage quality enhancement technology that combines a Static Var Generator (SVG) and a Dynamic Voltage Restorer (DELTA). The verification test shows that the technology has good practicality.
