Electric vehicles and the electric grid: A review of modeling approaches, Impacts, and renewable energy integration
TLDR
A review of the current literature on EVs, the electric grid, and renewable energy integration is presented in this paper, where the economic, environmental and grid impacts of EVs are reviewed.Abstract:
Electric vehicles (EVs) and renewable energy sources offer the potential to substantially decrease carbon emissions from both the transportation and power generation sectors of the economy. Mass adoption of EVs will have a number of impacts and benefits, including the ability to assist in the integration of renewable energy into existing electric grids. This paper reviews the current literature on EVs, the electric grid, and renewable energy integration. Key methods and assumptions of the literature are discussed. The economic, environmental and grid impacts of EVs are reviewed. Numerous studies assessing the ability of EVs to integrate renewable energy sources are assessed; the literature indicates that EVs can significantly reduce the amount of excess renewable energy produced in an electric system. Studies on wind–EV interaction are much more detailed than those on solar photovoltaics (PV) and EVs. The paper concludes with recommendations for future research.read more

A critical review of electric vehicle charging using solar photovoltaic
TL;DR: In this article, the authors provide the background on the EV fundamentals, batteries and a brief overview on the solar photovoltaic (PV) systems, and a case study is carried out in comparison to the grid-only charging to critically analyse the technical and the economical feasibilities of both types using Matlab simulation.

Day charging electric vehicles with excess solar electricity for a sustainable energy system
TL;DR: In this paper, the authors explore the possible complementarities between wind and solar power and electric vehicles charging, based on 2050 scenarios for the case study of Portugal, and show that CO2 emissions targets can only be achieved with high levels of photovoltaics penetration and EVs, reinforcing the need for daytime charging infrastructures, presumably at or near work facilities.

Key factors for assessing climate benefits of natural gas versus coal electricity generation
TL;DR: In this paper, the authors identify power plant efficiencies and methane leakage rates as the factors that explain most of the variance in greenhouse gas emissions by natural gas and coal power plants.
