Modelling and simulation of solar pv & csp based e.v charging station

Limited fossil fuels focused the entire world for developing new Renewable energy sources for electricity generation. In order to ensure secure and steady performance of power distribution network, it is essential to analyses the impact of EV charging stations on the power grid as well as possibility to make economical this system through solar roof top system. The prospective spread of electric vehicles (EV) and plug-in hybrid electric vehicles leads to the need for fast charging rates. Higher charging rates lead to high power demands, which cannot be supported by the electrical grid. Thus, the use of on-site sources alongside the electrical grid for EV charging is a rising area of interest. This paper proposes an innovative integrated bidirectional converter with a single-stage onboard charger to reduce the number of switches, size, and weight of the power electronic interfaces. However, the PV output power has an intermittent nature that is dependent on the weather conditions. Thus, battery storage is combined with the PV in a grid-tied system, providing a steady source for on-site EV charging in a renewable energy based fast charging station. Renewable energy based fast charging stations should be cost effective, efficient, and reliable to support the high charging rates demanded when a large number of EVs are connected to the electrical grid.
