Design and Sizing of Electric Bus Flash Charger Based on a Flywheel Energy Storage System: A Case Study

At present, the trend of all sectors and industries, especially oil gas industry, is towards reducing carbon dioxide emissions. Along with modernization technological processes, special attention has been paid to reduction in greenhouse emissions from vehicles that run on gasoline diesel. An effective solution this field transition combustion engines electric vehicles, similar use bus public transportation. How charge these buses a challenge for researchers. By proposing flash charging method buses, feasibility using obtained. Due pulsating nature power demand method, prevention negative effects network by type load should be considered. These can include quality problems, voltage drop, frequency instability, overload transmission lines transformers. This paper presents flywheel energy storage system (FESS)-based station buses. The specifications components are designed sized case study line 1 Tehran Bus Rapid Transit (BRT). A strategy based proposed cycle presented minimize high-power short-duration grid. consumption electricity model calculated. Based theoretical calculations, study, there need installing 12 stations FESS BRT. In line, an battery capacity 80 kWh proposed. 600 kW 3.334 kWh, respectively. Additionally, economic comparison regarding conducted. results design sizing validated simulation experimental small-scale laboratory setup.
