Independent pre-assembled integrated micro power grid system for far reef island

The invention provides an independent pre-assembled integrated micro power grid system for a far reef island. The micro power grid system includes a pre-assembled integrated micro power grid house, an island wind power generation system, an island photovoltaic power generation system, a diesel generator, resident load, and garrison load, wherein the pre-assembled integrated micro power grid house, the island wind power generation system and the island photovoltaic power generation system access an alternating current (AC) bus; the AC bus supplies power for the resident load and the garrison load through a transformer and a power transmission line; and as photovoltaic thin film cell assemblies are paved on the top and the sunny side of the micro power grid house and a mini type axial flow wind driven generator is arranged on the top of the micro power grid house, the power supply requirement for power utilization for the own industrial air-conditioners of the micro power grid house and the equipment in a micro
