Research on Capacity Optimization Configuration of Incremental Distribution Network with Hydrogen Energy Storage

The combination of electrolytic hydrogen with wind and photovoltaic power generation has become a trend in the development of power systems. How to effectively allocate wind, solar and hydrogen in the power grid and rationally utilize hydrogen energy storage is an urgent problem that needs to be solved. A capacity optimization configuration method of incremental distribution network with hydrogen energy storage was proposed in this paper. A capacity optimization configuration model is constructed with the goal of optimizing the profits of investors throughout the life cycle. The functions and proportions of hydrogen storage tanks in electricity-hydrogen-electricity conversion were designed. The impact of different ratios of hydrogen storage tanks on capacity optimization configuration was studied. The example study shows that the method proposed in this paper can better take into account optimization configuration requirements such as economic costs, effective utilization of renewable energy, and reliability of energy supply.
