Abstract
This study presents an optimal operation scheme for a quadruple-active-bridge (QAB) based unified power quality conditioner (UPQC) integrated with photovoltaic (PV) under VA capacity constraints. Due to the removal of the low frequency isolation transformer and the energy router functionality of the QAB converter, higher power density and more flexibility can be achieved for the UPQC-QAB. Thus, it is convenient for the PV arrays to be integrated at the DC-links to supply the load through the UPQC-QAB. In the constrained multi-objective optimization problem, the maximum power generation of PV arrays, the minimum load voltage deviation, the maximum power factor of the power grid and the minimum total apparent power of the UPQC-QAB are determined. Based on hierarchical optimization idea, the multi-objective optimization problem is simplified as several single-objective optimization ones. Finally, simulation results verify the correctness and effectiveness of the proposed optimal operation scheme.
