A Review Article on Comparison Between Utility Grid Connected V2G System and Without Utility Grid Connected V2G System
Abstract
Today is a renewable energy generation based era. In accordance with the efforts to reduce CO2 emission and reduce the dependence on fossil fuels for energy generation, a variety of renewable energy resources are penetrating more into the power grid. Almost more than 60% of the world’s oil productions are consumed by vehicles on roads. Gas driven internal combustion engines are low efficiency systems that emit several harmful gases and establish an unsustainable and inefficient transportation system. These are harmful effect reduced by energy generation by renewable energy source and using electrical vehicle in transportation. In a study, it is reported that vehicles are responsible for 30% of the world total energy consumptions and 27% of total greenhouse gas emissions. Hence, to eliminate emissions originated from urban life, grid-connected vehicles have been recognized as one of the effective option. These are harmful effect reduced by energy generation by renewable energy source and using electrical vehicle in transportation. In this study two V2G case are considered ,first without utility grid connected V2G system and secondly utility grid connected V2G system and it is observed that, the transient effect of all parameters are reduced, and performance of V2G system are improved. Hence stability of V2G system by using utility grid gets improved.
