The next generation of photovoltaic (PV) system is expected to provide ancillary service function during grid voltage drop such as low-voltage ride-through (LVRT) capability. During such voltage drop, the distributed generation (DG) should remain connected to the grid and at the same time injecting a reactive power to provide a voltage support. The LVRT function in wind-based electricity generation is already established due to its maturity. However, the LVRT implementation in PV system is just at the beginning where there are still many rooms to be investigated and improved. Thus, this paper proposed an enhanced LVRT control strategy which is based on simple PI-scanning to improve the LVRT capabilities. Simulation done in MATLAB environment has confirmed the effectiveness of the system in providing continuous voltage support to the grid.
