Fast charging priority optimization technique for a multi-port EV charging station

Transportation is moving rapidly towards the electrification, with targets and deadlines set by governing bodies. This shift will increase the pressure onto energy regulators, adding to current challenges facing the energy industry. The needs new infrastructure, smart energy solutions and multiple industries to collaborate to support a rapid and reliable transition to electrification of transportation. This paper analyses a fast-charging priority method for electric vehicles, powered by renewable energy with incorporated battery storage system. Priority charging enables users to charge their vehicles fast and efficiently based on their preferences. The inclusion of a renewable energy microgrid reduces the stress onto the transmission and distribution network. To meet the high energy demand during peak period a storage system provides support to the microgrid. The solution is simulated on Simulink. Results illustrate that a controlled charging system can reduce the stress onto the energy industry, satisfy users financial needs and rapidly enable the inclusion of electric vehicles by reducing common problems related to charging timing. With a standalone charging station, the concept of dynamic prices can be introduced, which can change the price for charging according to the power generated dependant on the demand from the charging ports, in real time.
