The number of charging piles in each charging station is 145 (station 5), 140 (station 9), 145 (station 10), 150 (station 11), and 150 (station 12). Fig. 8 shows the charging stations and PV power plants planning result.
This paper explores the performance dynamics of a solar-integrated charging system. It outlines a simulation study on harnessing solar energy as the primary Direct Current (DC) EV charging source. The approach incorporates an Energy Storage System (ESS) to address solar intermittencies and mitigate photovoltaic (PV) mismatch losses.
More energy is generated and stored at higher solar irradiance levels, so more power is available for EV battery charging. As a result, the SOC of the EV battery rises in proportion to the energy conveyed to it.
The number of charging piles in a charging station is 120 (for stations with 8, 14 piles), and 135 (for a station with 10 piles.
Solar energy, harnessed from the sun, offers an abundant and clean power source, presenting an optimal solution for sustainable EV charging . However, solar intermittencies and photovoltaic (PV) losses are a significant challenge in embracing this technology for DC chargers.
However, solar intermittencies and photovoltaic (PV) losses are a significant challenge in embracing this technology for DC chargers. On the other hand, the Energy Storage System (ESS) has also emerged as a charging option. When ESS is paired with solar energy, it guarantees clean, reliable, and efficient charging for EVs [7, 8].
