A DC microgrid power generation, transmission and distribution system provided by the present invention includes a hydrogen fuel generator set, a DC / DC conversion device, a DC750V DC microgrid and user power conversion equipment; wherein, the DC busbar of the DC750V DC microgrid is provided with Battery energy storage system; the battery energy storage system includes an energy storage battery pack and a bidirectional DC / DC charging and discharging device; the power generated by the hydrogen fuel generator set is incorporated into the DC750V DC microgrid through its corresponding DC / DC conversion device, when the DC750V DC microgrid If there is a sudden change in the voltage, it will be connected in parallel to the DC750V DC microgrid to dynamically adjust the voltage on the DC bus of the DC750V DC microgrid through a bidirectional DC / DC charging and discharging device, and dynamically adjust the output voltage and power of the hydrogen energy transmission according to the actual situation to maintain the DC microgrid. The DC bus voltage of the power grid is stable, maintaining the stability of the instantaneous power output to the user's electrical equipment.
Description
Technical field [0001] The present invention relates to the field of hydrogen fuel transmission and distribution distribution technology, and more particularly to a DC microgrid transmission distribution system. Background technique [0002] Hydrogen can be in its own resources, widely used, and has no pollution in the process of hydrogen production and hydrogen fuel power generation, and is called the world's clearest new energy source. The application process of hydrogen energy is generally generated from the hydrogen fuel cell to the DC microgrid to reach the electrical converter, and finally to the user's electric conversion device, but the output voltammetry of hydrogen energy battery is poor, resulting in hydrogen energy transmission. The output voltage and power are unstable, affecting the normal use of the user's electric conversion device. Inventive content [0003] The technical problem to be solved by the present invention is that the output voltammetric characteristi...
