摘要

In this paper, the operation and control of photovoltaic-fed unified power quality conditioner in grid-connected mode including the power quality enhancement feature has been systematically examined. The current harmonics, voltage sags, voltage swells, voltage unbalance, dc-link voltage regulation are the primary factors limiting the performance of the AC system. Therefore, these power quality issues are needed to be eliminated by high-performance power conditioners controlled through highly effective control strategies. In this paper, an optimization algorithm is used to amplify the controller performance by achieving the best numerical parameters for proportional plus integral controller of PV-UPQC. Detail analysis involving elimination of current harmonics, voltage sags and voltage swells are investigated to analyze the effect of novel optimization algorithm on controller of photovoltaic-fed unified power quality conditioner system. In addition, this paper proposes double second-order integral quadrature signal generator-based phase-locked loop mechanism for proper grid synchronization. Finally, experimental verification of the performance of the proposed scheme by hardware prototype development has been included.
