Design of Solar-Powered Charging Station for Electric Vehicles in Power Distribution System

This paper presents an analysis of installation of solar powered charging station in power distribution system. The 9-bus primary distribution system was used to test the power flow using the Newton Raphson method, comparing the size and voltage angle with the DIgSILENT program. The 3-bus test system is used to analyze the installation of the charging station for a solar electric vehicle in distribution system. The power flow was analyzed by determining the solar energy source and the electric vehicle load in time series. The model of solar charge stations and the size of electric vehicles are determined at 100 kWh. The results of the power flow test using the Newton Raphson method found that the test results were in error by comparing the size and voltage angle with the DIgSILENT program that maximum value of at Bus no. 9 is 2.04% and -3.91%, respectively. While testing the analysis of solar powered charging station, it is found that the charging time will affect the power loss of the system and the maximum energy demand. The simulation, it is found that the suitable solar panel size must be greater than 7.39 kWp. Therefore, the electrical system design study using the PyPSA program to analyze of the solar powered charging station in distribution system shows the application in the design of the electrical system to support the load expansion from of electric vehicles and solar powered charging stations in the future.
