Impact of Electric Vehicle Charging Station in Distribution System Using V2G Technology

The electrification of the transport sector is playing a vital role due to the depletion of the fossil fuels and emission of the carbon gases over the atmosphere, which leads to increase in the global warming. As a result, the usage of Electric Vehicles (EVs) is going to increase day by day in the transportation sector. Usage of EVs might reduce the pollution but it will increase the load on the grid, which further increases the losses in the power grid system. As the EV can act as a load and source with a bidirectional converter having dual mode of operation using Vehicle-to-Grid (V2G) Technology, which is going to act as a Distributed Generation (DG) during peak time of charging and as a load during off-peak time. In order to reduce the losses on the grid, modelling of EVcharging behaviour is key to estimate the charging needs and beyond. In the proposed model, an IEEE 33-bus system integrated with four electric vehicle charging stations (EVCS) of 10th, 14th, 17th and 30th buses was considered to analyse the performance of the system. Also, to estimate the load demand of distribution system for a 24 h duration based on the load setting for the 33-bus system. The simulation results of the V2G model will show the reduction of losses in the distribution system using V2G method.
