A distributed household energy storage system comprises an inverter, a wind-solar complementary controller and a storage battery used for storing valley power, photovoltaic power and wind power. The distributed household energy storage system supplies grip power to household electrical appliances in a valley period of a power grid, stores the grid power in the valley period to the storage battery through the inventor, and stores the wind power and photovoltaic power in the valley period to the storage battery through the wind-solar complementary controller; the system supplies the wind power and photovoltaic power to the household electrical appliances preferentially in a common period of the power grid, and the insufficient portion is supplemented from the storage battery; and the system supplies the wind power and photovoltaic power to the household electrical appliances through the wind-solar complementary controller and the inverter in a peak period of the power grid, and supplies the power in the storage battery to the household electrical appliances through the inverter. The distributed household energy storage system saves energy, is high in energy utilization rate, and reduces total energy consumption.
