Abstract: With the integration of high-penetration distributed photovoltaic (PV) systems into distribution networks, voltage violation and fluctuation issues have become increasingly prominent, making traditional voltage regulation methods inadequate for meeting actual operational requirements. Therefore, starting from the mechanism of voltage rise caused by PV grid integration, this paper establishes a voltage response model that accounts for reverse power flow and dynamic fluctuation characteristics. A distributed adaptive control strategy based on reactive power-voltage and active power-voltage coupling is proposed. Furthermore, a multi-feeder edge collaborative control framework integrating OLTC, PV inverters, and reactive power compensation devices is constructed. Grid-connection tests and emergency response analyses conducted in the context of an actual distribution network retrofit project validate the effectiveness of the proposed method in suppressing voltage violations, improving system stability, and enhancing fault recovery capability.
