Assessing Centralized and Decentralized EV Charging Schemes using PV-Grid Connected System, Case Study in Egypt

Egypt’s vision 2030 aims to reach a diversified, balanced, and competitive economy through the sustainable development basis. Electric vehicles (EVs) as well as renewable energy have an important role to play. Both, electric vehicles, and renewable energy resources are deeply involved in the Integration of Sustainable Energy Strategy year 2035 (ISES2035), which was released in 2015 by the Ministry of Electricity and Renewable. Introducing electricity to transportation has been developed to support CO2 decrease and energy effectiveness. Consequently, electric vehicles have become more popular in the current transportation system to utilize more effective and environment-friendly energy. The energy sectors integration concept aims to use the renewable energy sources in transportation as well as in power generation. In this research a comprehensive study was made to compare the techno-economic effectiveness of centralized DC fast charging schemes, with decentralized (indoor/overnight) AC charging schemes. In both scenarios photovoltaic (PV) system is assumed to charge the battery of electric cars making use of the current net-metering scheme that applied in Egypt.
