The world is closer day by day with the advances in transportation and, it results in widely diverse cultures and diseases. The fast spread of Covid 19 is a side effect of this global village, however, science and modern bioengineering are making it possible to overcome and expected to meet the endemic soon.
The city of Oviedo has renewed its urban bus fleet this year 2022. The company ALSA and the City Hall have purchased 19 Mercedes Benz Citaro Hybrid, 1 eCitaro full electric, and 2 Sprinter City 75 vans with low emissions–. These buses accounted for 38% of the total fleet, which is now ECO or Zero Emissions (according to EURO VI regulations). On top of that, with this purchase, the urban bus fleet's average age is reduced to 4.3 years.
Smart grids have important challenges for incorporating electrical mobility, especially in emerging countries. Due to new requirements associated with ultra-grid penetration, electrical mobility, and the new aspects of the medium voltage grids; it could be a limit for this technology without a new infrastructure or changes in the grid. In this research, a new methodology is proposed with seven steps. For electrical mobility in Perú, the electrical networks with Photo-voltaic Solar panels and fast-charging stations for emerging countries have new effects as overload in transformers, inverter control and modeling for chargers and distribution transformers should be reviewed, due to loads transfer, voltage sag, and losses, the impact is high in a short term. These results provide challenges for government, industry, and prosumers. Results have demonstrated voltage sag are from 5.68% to 3.81%, losses from 0.112kW to 0.12kW, voltage transformer from 1.21% to 1.09%, and transformers rotations with a detailed load density analysis with 20% penetration with fast charging stations and 40% of ultra grid penetration with photo-voltaic generators, with original mitigation associated to control in inverters and seven steps in the methodology.
