Heuristic Storage System Sizing for Optimal Operation of Electric Vehicles Powered by Photovoltaic Charging Station

الملخص EN

This paper discusses the utilisation of PV systems for electric vehicles charging for transportation requirements of smart cities.

The gap between PV power output and vehicles charging demand is highly variable.

Therefore, there is a need for additional support from a public distribution grid or a storage device in order to handle the residual power.

Long term measurement data retrieved from a charging station for 15 vehicles equipped with a PV system were used in the research.

Low and high irradiation seasons influenced the PV output.

The charging demand of electric vehicles varied over the course of a year and was correlated to weather conditions.

Therefore, the sizing and performance of a supportive storage device should be evaluated in a statistical manner using long period observations.
