This　paper　presents　a　novel　control　strategy　of　the　two-stage　three-phase　photovoltaic　(PV)　system　based　on　the　active　and　reactive　power　control　to　improve　the　low-voltage　ride-through　(LVRT)　capability.　With　the　help　of　the　new　strategy,　the　PV　array　can　generate　the　appropriate　active　power　according　to　the　depth　of　the　grid　voltage　dip　to　restrain　the　over-voltage　and　over-current.　Simultaneously,　the　proposed　strategy　can　ensure　the　reactive　power　support　to　help　the　voltage　recovery.　Besides,　a　feed　forward　compensation　is　used　to　smooth　the　DC-link　voltage　fluctuations　during　the　grid　fault.　The　effectiveness　of　the　proposed　control　strategy　is　verified　through　various　simulation　scenarios　when　different　grid　voltage　drop　depths　occur.　The　proposed　control　strategy　can　not　only　enhance　the　LVRT　capability　of　the　PV　system,　but　also　provide　the　reactive　power　support.
