Abstract: A reduced-order analytical model to evaluate the performance of PV in case of low-voltage ride through(LVRT)was proposed based on the idea of order reduction at each unit, focusing on the DC bus voltage which determined the outcome of ride-through. Such a method covered the major factors with regard to PV LVRT, and included the responses by the converter controller and phase-locked loop. Meanwhile, it took the supporting of reactive power outputs from PV on the point of common coupling(PCC)voltage into consideration, so as to reflect that PV provides reactive power support to AC system. To validate the proposed reduced-order analytical model, the comparison with the simulation results derived from PSCAD confirmed its accuracy and feasibility.

Key words: reduced-order model, dynamic model, reactive power support, grid-connected photovoltaic system, low-voltage ride-through
