technical field [0001] The invention relates to the technical field of power system optimization, in particular to a method for optimizing the operation of a distribution network including hydrogen production-hydrogen storage-hydrogen refueling stations. Background technique [0002] Under the background of vigorously advocating the development of green energy, photovoltaic power generation as the main form of new energy power generation has become a current research hotspot. Since new energy power generation will be affected by environmental conditions, its output power will fluctuate, which will affect the quality of its output power. At present, the mainstream solution is to cooperate with the energy storage system to convert the electricity generated by photovoltaics into other energy for storage. After that, it is converted into stable electric energy for output. Among them, hydrogen energy has received extensive attention due to its cleanness and high efficiency. The ...

Problems solved by technology

If the hydrogen refueling station is used to perform energy conversion to supply power to the grid, then, while supplying power to the grid, the hydrogen refueling station also has the responsibility to provide hydrogen energy to hydrogen energy, which leads to the existence of hydrogen refueling stations when they supply energy to the grid. The voltage deviation problem, especially during the peak period of hydrogen energy vehicle hydrogenation, the voltage deviation problem of the hydrogen refueling station to the grid power supply will become more serious

This may affect the safe and stable operation of the power system
