Abstract： With the large-scale integration of high-proportion distributed photovoltaics （PV） into low-voltage transformer districts， voltage and power flow violations have grown increasingly prominent. The traditional centralized head-end voltage regulation method relies on a single large-capacity device to manage voltage for all nodes along the line， but in PV transformer district with severe reverse power flow， forcibly adjusting the voltage to meet the standard at the end nodes may cause voltage violations at the head-end nodes， making it difficult to satisfy the differentiated voltage regulation requirements among multiple nodes. To address this issue， a multi-device coordinated voltage regulation method is proposed. Based on line topology and load distribution， the power line at the transformer districts is split into two sections （front and rear）. Some capacity of the head-end and end-end voltage regulating devices are deployed separately in each section， transforming the full-line voltage regulation task that is originally required to be independently undertaken by a single traditional voltage regulating device into segmented collaborative regulation by two voltage regulating devices. This multi-device coordinated voltage regulation method that decomposes the voltage regulation task can not only reduce the system's total capacity requirement for voltage regulation devices， but also enhance the flexibility of voltage adjustment， ultimately achieving wide-range regulation with small-capacity equipment.
