Real-time Voltage Control Method Of distribution Network Based on Local Control Curve

The proliferation of photovoltaic (PV) integration in distribution networks introduces critical operational challenges, including voltage violations, unbalanced power distribution, and consequent degradation of end-user power quality. To address these issues, a real-time voltage control method based on local control curve is proposed. The proposed method is used to solve the problem of voltage violation at distributed energy access points. Meanwhile, a hardware-in-the-loop platform combining a realtime simulator and Raspberry Pi devices is developed to validate the proposed method.Experimental results demonstrate enhanced voltage quality and robustness of distribution networks under dynamic conditions.
