Modelling of Residential Distribution System with Aid of Electric Vehicles for Improve the Voltage Profile

Electric vehicles offer an effective and tangible solution to reducing pollution, combating environmental change and thereby improving energy security. However, the potential for widespread EV adoption poses significant barriers to the operation of residential distribution systems, depending on how and when EVs are charged. This new mode of transport and infrastructure requires reliable and safe energy management solutions. It must be ensured that the electric vehicles and their charging infrastructure are safe, convenient, energy-efficient and economical for everyone involved. In addition, grid operators must ensure that they can easily control the charging and discharging of electric vehicles in the distribution grid. Certainly, when properly integrated, electric vehicles can bring benefits to both energy providers and their owners. In this article, we investigated bi-directional EV charging in a residential radial distribution system to improve the system's voltage profile by optimizing EV charging and discharging. The Radial Residential Distribution System is simulated in MATLAB 2016a with different scenarios and the results are presented.
