Modelling and Simulation of a V2g/G2v Electric Vehicle Charging Station

Abstract

Due to the rise in carbon footprint, there is a massive pull towards EVs in mobility. Even governments are promoting and defining new E-mobility policies to tackle this rise in environmental pollution by internal combustion (IC) engine vehicles. So, there is an expected hike in electric vehicles (EVs) nearby, but from the power system point of view, this hike reflects as the rise in the load for the electric grids they shouldhandleby providing sufficient power, thus generation meets demand. Renewable sources like photovoltaics could be a great optionto meet the rise in demand and they aregood for environmentbut due to intermittency of solar energy it cannot be used directly to balance the demand. So, this energy should be stored to make use it efficiently when there is a demand.To support the grid, Concept of V2G proposed.where, battery inside vehicle can be used as a storage device and use the energy from battery while Vehicle is not in use. So, V2G charging stations are important to implement this technology. Current charging stations in India support only unidirectional charging. There is a need for research in optimizing V2G technology. This paper presents a V2G/G2V converter which is modelled and simulated in MATLAB/Simulink (2019). The amount of active and reactive power injected to the grid is controlled using the pi controller, with decoupled DQ controlscheme and further, it is performance and efficiency is estimated.
