This paper focuses on the feasibility and techno-economic analysis of electric vehicle charging of PV/wind/diesel/battery hybrid energy systems with different battery technology, which is the first in Ethiopia, and includes PV and Wind power sources, different technology battery storage, diesel generator and grid connection.
Of all feasible systems, the Wind Turbine (WT)/PV/LI, PV/LI and WT/PV/LI configurations have the highest values of NPC and COE in Addis Ababa, Jijiga and Bahir Dar. Using this configuration, the results demonstrate that ZnBr battery is the most favorable choice because the economic parameters, including total NPC and COE, are found to be lowest.
Furthermore, in Addis Ababa, Jijga and Bahir Dar, the renewable fraction, which is the percentage of energy provided to the load that comes from renewable power sources, was 92.8%, 96.6% and 93.7%, respectively. The monthly average electrical energy production of the PV/DG/ZnBr systems in Addis Ababa is illustrated in Figure 10.
In Bahir Dar, the optimal hybrid energy system is an initial capital of $ 2,307,413.03, an operating cost of $ 41,890.54/year, a total NPC of $ 2,848,954.00 and a levelized COE of $ 0.1877/kWh with a CC strategy.
[ 20] proposes a novel fast charging strategy to charge lithium-ion batteries safely, which includes a voltage spectrum-based charging current profile that is optimized using a physics-based battery model and a genetic algorithm to address the shortcomings of long charging times and charging-related degradations.
