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.

Micro grid stabilization device

An electrical energy supply system providing voltage to a load and including an external power group and a DC supply device is disclosed. The external power group provides an external voltage. The DC supply device includes a bus, a converting unit, a storage unit and a smart energy management system (SEMS). The bus receives the external voltage and is coupled to the load. The converting unit converts the external voltage into a converted voltage or converts a stored voltage to generate a converted result and provides the converted result to the bus. The storage unit stores the converted voltage or provides the stored voltage to the converting unit. The SEMS controls at least one of the converting unit, the external power group and the load according to at least one of the external voltage, a voltage level of the bus and a voltage level of the storage unit.
