One of the most typical distributed generation systems are electrical microgrid, which consist on small electrical
grids, generally connected to the main grid, with a decentralized management structure. Electrical microgrids allow
higher renewable energy integration in the grid, achieving a cost decrease and improving the grid quality [1]. These mi-
crogrids incorporate renewable generation systems and energy consumers. Moreover, they have storage systems to
balance generation and consumption as well as the exchanged power with the main grid. Traditionally, lead-acid batter-
ies have been used in microgrids. However, these batteries have some drawbacks, being the most important its poor
performance in partial state of charge, which is critical for a microgrid. A suitable option for the storage system is hy-
drogen technology. These systems have high energy density, which makes the storage system able to assume seasonal
variability of renewable resources.
This paper proposes a sizing methodology for storage systems based on hydrogen for grid-tied electrical microgrids.
This methodology optimizes the relationship between the storage system size and the consumption of grid power.
