But the cost of energy storage increases. The total microgrid costs are minimized for optimal battery size , . Fig. 1. Optimal BES sizing . The use of battery is not limited to microgrid and the economic approach is not the only approach for determining the optimal energy storage size.
Lithium-ion batteries (LIBs) and hydrogen (H 2) are promising technologies for short- and long-duration energy storage, respectively. A hybrid LIB-H 2 energy storage system could thus offer a more cost-effective and reliable solution to balancing demand in renewable microgrids.
The battery is charged at 3 and 8 o'clock when the energy price is relatively low, and at 17 and 19 o'clock when the energy price is the highest value, it is discharged and part of this power is delivered to the grid and profitability is achieved for the microgrid.
The use of battery is not limited to microgrid and the economic approach is not the only approach for determining the optimal energy storage size. In , , energy storage size is determined based on frequency maintenance in a microgrid disconnected from the grid, and economic issues are not considered in these studies.
In the hybrid-storage microgrid analyzed in this study, electricity is generated only by local wind power resources, while a hybrid LIB-H 2 energy storage system bridges mismatches between wind energy supply and electricity demand. In the H 2 subsystem, electricity is converted to H 2 using a proton exchange membrane (PEM) electrolyzer (El).
