N2 - Low voltage regulator (LVR) units have been developed and deployed in low voltage distribution systems to maintain the voltage of those systems within a proper range. Unfortunately, while an LVR can maintain a constant secondary voltage, under current methods, it cannot ensure that individual node voltages remain within prescribed limits. To address this deficiency, we propose a dynamic voltage control method for LVR based on integration of a load drop compensator (LDC). This LDC-based method decreases voltage deviation by adjusting parameters based on the estimated secondary voltage and current, while its predictive control limits rapid fluctuations using direct tap control based on the predicted node voltage. Numerical simulations indicate that the proposed method decreases voltage deviation more than conventional methods (90Relay and LDC method).
