Smart topology of EVs in a PV-grid system based charging station

This work focuses on a smart algorithm to optimize energy of electric vehicles charging station while considering numerous constraints as the instability of renewable energy sources and the potential limited power given by the grid. The PV array is considered as a basic source of energy to feed the charging station system, directly tied into a voltage DC bus, thus the lithium-ion battery is implemented in this platform to complete the power flow of each potential charging scenario. Moreover, the management algorithm is taking into account the fluctuant power state of both the DC and the AC bus link, and it treats also the state of charge of the batteries in the energy management approach.
