Abstract:
This thesis presents a simulation-based analysis of a home microgrid system in
PV-battery electric vehicle (EV) charging system and electrical energy trading. PVsyst
program was used to simulate the 15.87 kWp rooftop solar power generation system for
a home that consumed more than 150 kWh of electricity each month. Then a
comparison was conducted between fast charging EV energy to normal charging EV
energy by using Homer Grid program to study the effects of the energy generated by the
microgrid system.
A simulation analysis of the energy generated from the microgrid system of four
EV brands with engine powers of 105, 110, 120 and 110 kW, respectively, was performed
by charging an electric vehicle at 8.00 p.m. Moreover, an analysis of financial investment
was explored by employing fast EV charging system for the 120 kW charger in terms of a
break-even point analysis, a net present value analysis, and a payback period analysis.
The findings of the study revealed that the energy utilized to fast charging and
normal charging of EV which had been simulated by Homer Grid program for an EV
battery charge was 8 kWh/day on average or equivalent to EV running 23,000 km/year,
with a 20-minute charge period at 8.00 p.m. Regarding to a comparison of the energy
required to charge the 4 EV brands, it was found that No. 2 brand consumed the most
energy during fast charging with a charging energy value equal of 3,096 kWh/year while
No. 4 brand used the most energy for normal charging with 2,859 kWh/year. Lastly,
referring to the purchase cost of electric power from the Metropolitan Electricity
Authority (MEA), the price was 76.80 kWh/year.
