Abstract :
Global warming, the limitation of non-renewable resources such as fossil fuels and the requirement to reduce global CO2 emissions by 20% by 2050, which has been introduced by the International Energy Agency, have given great attention to the use of electric vehicles as a main transportation solution. It has created a legend in the world. The significant increase in the production of electric vehicles and the unplanned and controlled use of electric vehicles are considered as additional loads for the power grid, and may be caused by overloading the grid equipment, disrupting the stability of the grid voltage and injecting harmonics. to the power grid, create possible risks for the reliability of the power grid. On the other hand, EV can be a promising future technology that can be connected to the grid as mobile energy storage to create a smart grid application. In the proposed method, using intelligent planning of charging and discharging of electric vehicles based on the charging level of the selected vehicles with the help of PSO optimization algorithm by performing load leveling and peaking and also providing the required power with the participation of the energy produced from the available PV cells. improve the voltage profile of the distribution network. The network studied to evaluate the proposed algorithm in this research is the standard IEEE bus 33 network and coding has been done in the MATLAB software environment.
