Development of Hybrid Station for G2V, V2G using SPWM and ABC-DQ Technique

Abstract

Considering present transportation scenario, pollution caused by the conventional vehicle is one of the major reason for global warming. With these growing pollution concerns, and recurring hikes in the prices of the petroleum an increasing effort is being done to replace the pollutant combustion engines to Electrical Vehicles (EVs). EVs are considered as sustainable transport alternatives due to their lower energy consumption, less pollutants production and efficient features such as sudden torque, noiseless ride, superior performance, low maintenance costs and also creates cleaner environment. For the growth of EVs, it requires more charging networks thus allowing EV user to quickly charge the battery for long routes drives, also in the scope of smart grids, EVs should also be able to provide ancillary services to the grid. In the paper, the hybrid charging station helps to perform different mode of operation such as grid to vehicle (G2V and vehicle to grid (V2G). For that, charging station configuration has divided mainly into three stages, grid side, hybrid station side and EV side. Here AC/DC bidirectional converter is controlled using sinusoidal pulse width modulation technique (SPWM) and abc-dq technique incorporating phase locked loop (PLL). Thus this methods helps to transfer electrical power from the grid to an EV and back to the grid. Analysis has been done in MATLAB/Simulink to illustrate the performance analysis.
