The high cost of hydrogen energy storage limits the energy storage configuration of a small renewable energy microgrid system, which results in the lack of flexibility of the microgrid system. Although the “shared energy storage” mode has been proposed, the “shared hydrogen storage” involving multiple links is not mature.
The research on hybrid energy storage mainly focuses on evaluating the combination configuration of different types of energy storage. With the development of hydrogen energy technology, the application of hydrogen energy storage technology in multi-energy system has attracted more and more attention.
The capacity of hydrogen storage in the microgrid cluster scenario is lower than that in the microgrid independent scenario. This is mainly due to the cluster of microgrids and the sharing of energy storage. First of all, the resources within the microgrid cluster are optimized, and the demand for energy storage will be reduced.
Amin Mansour-Saatloo et al. proposed an optimized energy management strategy for combining hydrogen, heat and electricity with a microgrid and hydrogen fuel station for hydrogen fuel vehicles, electric vehicle parking lots and fuel cell micro-cogeneration to meet the demand of electricity and heat .
Equivalent hydrogen storage model The equivalent hydrogen storage model is presented in (6g). Constraint (6a) defines the relationship between SoC, charge power, and discharge power. Constraints (6b) limit the SoC of hydrogen storage within the bounds. Constraint (6c) guarantees ensures a sustainable energy state for hydrogen storage over cycles.
The SoC of hydrogen storage can be measured by the hydrogen mass or as a ratio of the rated capacity. E t H,L is the hydrogen load, such as fertilizer manufacturing and steel-making. E H and E ¯ H are the lower and upper bounds of SoC. P H and P ¯ H are the lower and upper bounds of power.
