Abstract: A clean energy power supply system includes a container, a thermal insulation wall, a power-generation device, a power-conversion device, and a power-distribution device. The container has an internal space and a rear door. The thermal insulation wall is located in the internal space and adjacent to the rear door. The power-generation device is disposed in an accommodating space of the container and configured to generate a clean power. The power-conversion device is disposed in the accommodating space and configured to convert the clean power into a converted power. The power-distribution device is disposed in the accommodating space and configured to output the converted power to an external load or an external power grid. The thermal insulation wall is configured to block external airflow flowing through the rear door so as to maintain the temperature of the accommodating space.

Abstract: A clean-energy power supply system is coupled between a power supply and a load. A first power generation device is configured to provide a renewable voltage. A power transformation device transforms the renewable voltage according to a first selection signal to generate a first transformed voltage or a second transformed voltage. A switch selectively transmits the first transformed voltage and the external voltage provided by the power supply to the load or transmits the second transformed voltage to the load. When the external voltage is not less than a predetermined value, the power transformation device generates the first transformed voltage and the switch transmits the first transformed voltage and the external voltage. When the external voltage is less than the predetermined value, the power transformation device stops generating the first transformed voltage and generates the second transformed voltage and the switch transmits the second transformed voltage.

Abstract: A micro grid stabilization device coupled to a DC bus and an AC bus in parallel is provided. A DC power generation apparatus provides power to the DC bus. An AC power generation apparatus provides power to the AC bus. A converter is coupled between the DC bus and the AC bus to transform the voltage of the DC bus and provide the transformed voltage to the AC bus. When the voltage of the DC bus or the AC bus is unstable, the micro grid stabilization device provides power to at least one of the DC bus and the AC bus to stabilize the power of the DC bus and the AC bus.

Abstract: A system and a control method of a mobile micro-grid are provided. The mobile micro-grid system includes a renewable energy source and a non-renewable energy source which are in a container. The control method includes supplying the renewable energy source as a primary power supply to an external load; and determining whether the electricity of the renewable energy source is sufficient. If the electricity of the renewable energy source is sufficient, then the renewable energy source provides electricity to the external load; if the electricity of the renewable energy source is not sufficient, then the renewable energy source and non-renewable energy source provide electricity to the external load. If an external power source, which is a renewable-energy-type power source, is connected to the mobile micro-grid system, then the renewable energy source and external power source work as the primary power supply.
