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.
Results and discussion The hybrid microgrid is comprised of the wind farm and the hybrid storage system, which is divided into the LIB and H 2 subsystems. The LIB subsystem consists of LIBs and can be described using LIB power capacity and LIB energy storage capacity. The two parameters are related using the LIB energy-power ratio.
Each string has 60 elements. The entire system has a rated capacity of 300 kWh/120VDC (2,500 Ah). The maximum Depth of Discharge (DoD) allowed is 40%. In the Ilha Grande microgrid, the energy storage system was designed to have 24-hours of autonomy and to meet a demand of approximately 130 kWh/day including power inverter losses.
Microgrids enable the deployment of renewables with reduced need for new transmission and distribution infrastructure. For microgrids with high shares of renewables, hybridizing LIB and H 2 storage can resolve issues of renewable variability/intermittency across multiple timescales.
Neither LIB nor H 2 storage alone achieve minimum cost for a 100%-wind supplied microgrid. A hybrid-storage system offers significant cost reductions. In the 2020 baseline hybrid-storage microgrid, total cost is distributed evenly among the three subsystems— H 2, LIB, and the wind farm.
MGs are a set of decentralized and intelligent energy distribution networks, which possess specific characteristics critical to the evolution of energy systems . There exist several definitions of microgrid in the scientific literature , , , .
