Energy Management of a Grid-Intergrated Hybrid Peer-to-Peer Renewable Charging Station for Electric Vehicles

Abstract

Electric vehicles are fast becoming a popular site in the world. Their technologies have been widely developed over the years. However, their charging infrastructure is still a subject of interest, as most of the electric vehicle charging requirements were previously met by an AC grid. However, over the year's research has been conducted on the implementation of renewable energies in the charging station. Most of the research studies focus on the management, optimal control, charging schemes and charging strategies. There is no research done on a charging station that combines the grid integrated hybrid renewable energy system such as Wind and PV comprising of a central battery bank with a peer to peer energy trading model. The aim of this research study is to develop a well-coordinated charging scheme of Electric vehicles in a charging station whilst optimally managing the charging and discharging of the central battery bank (used for energy storage) as well as the power dispatch of the grid and Wind and PV charging station. The proposed model will maximize electric vehicle user satisfaction that meets all the charging requirements of the charging station whilst offering cost effective charging scheme such as peer-to-peer energy sharing model.
