Abstract
Photovoltaic-based Unified Power Quality Conditioner (PV-UPQC) is one of the custom power devices widely employed for power quality improvement. A simplified control strategy is proposed for the PV-UPQC system with the objective to regulate the dc-link voltage, compensate the harmonics in grid current, and provide suitable control during a sudden change in the grid side or load side. Individual series and shunt converters in UPQC are controlled based on simplified instantaneous active and reactive power control theory that ultimately improves the power quality. Besides, active and reactive power flow between the PV, grid and load is also managed while maintaining the minimum dc-link ripple and balanced dc-link voltage. Interfacing inductors on both ends limits the high-frequency components. Different test cases are simulated in the Simulink platform to show the effectiveness in providing robust control for compensating power quality problems.
