The Impact of Electric Vehicles on Smart Grid
Acta Electrotechnica et Informatica, 2021
This publication examines the impact of electric vehicles on the grid. Electric cars are becoming more and more popular in the world. The annual sales quantity of electric cars in the world has an upward trajectory which has some serious implications on the electric grid as well. Both passenger and freight transport are being influenced by this current trend. In addition to various methods of transport, electric cars have the potential to transform traditional grids into smart ones. The primary objective of this study is to examine to what extent the voltage at the nodes changes when electric cars are connected to the network and also sets out to provide us with some overview of the effects on active power loss in the network.
Plug in Electric Vehicles in Smart Grid
The Plug-in Electric Vehicles (PEVs) are the Battery Electric Vehicles (BEVs) and Plug-in Hybrid Electric Vehicles (PHEVs). PEVs will dominate the transportation in the personal mobility mode and in the automobile market by 2030. Widespread adoption of PEVs brings potential, social and economic benefits. The focus on promoting use of electric vehicles in road transportation is very essential to meet the climate change targets and manage the ever hiking prices of fast depleting fossil fuels. However, there are lots of uncertainties in the market about the acceptability of PEVs by customers due to the capital and operation costs and inadequate infrastructure for charging systems. The penetration level in the market is not encouraging, in spite of incentives offered by Governments. Manufacturers are also not sure of the market, even though predictions are strong and attractive. Major manufacturers, however, are already ready with their plans to introduce electric vehicles to mass market. The use of PEVs has both technological and market issues and impacts. Series of research works have been reported to address the issues related to technologies and its impacts on political, economic, environmental, infrastructural and market potential aspects. Works dealing with suitable infrastructure such as charging stations and use of smart grids are reported. These steps are aimed to bring down the capital and operational costs that are comparable to the costing of conventional transport vehicles. The penetration level of PEVs in transportation will accordingly increase and keep the climate targets met and conserve fossil fuels for use in other economic segments. An overview on these issues is presented in this chapter.
Modelling the Impacts of Large-Scale Penetration of Electric Vehicle on Electricity Networks
Electric vehicles (EVs) offer several significant potential economic, social and environmental benefits -reductions in the transport sector's current very heavy reliance on petroleum-based fuels, improvements in urban air quality and reductions in transport sector greenhouse gas emissions. The batteries of electric vehicles, however, need to be recharged and electrification of transport systems will increase electricity loads, which could potentially place stress on some electricity distribution systems. The actual impacts of EV recharging on local distribution systems will depend on a number of factors and on the timing of the recharging events in particular. The results of the several studies have attempted to assess the potential impacts that EV recharging will have on local distribution networks suggest that coordinated managed charging of EV demand could actually have a significantly positive impact on distribution system reliability.

With the transitions of power systems from a traditional structure to a competitive structure, small-scale generators are expected to have a crucial and significant function in the electricity market. Small-scale generators are electric power generation sources that are used scattered in the grid to provide the electricity consumers need and are directly connected to the grid or the consumer's place. This is primarily driven by the move away from traditional power generation sources and regarding RES and EVs. Throughout the globe, utilities, sustainability, and communities all benefit greatly from this transition. Nevertheless, using EVs will have positive and negative effects on the distribution grid. There are many challenges for EVs and the grid when they are connected to the grid. It is essential to assess and analyze the integration of vehicles into the grid that incorporates detailed mechanical and electrical components of EVs and power systems. We examine two important analyses in the power system including RES and PHEV namely, load flow and short circuit calculation. Moreover, this paper defines three cases in load flow analysis and short circuit analysis for 63, 20 KV and explains economic analysis up to the cases, while using DIgSILENT, the analysis is carried out. In conclusion, the findings of this study highlight the signific
Impact of Penetration of Electric Vehicles on Indian Power Grid
World Electric Vehicle Journal, 2015
The research on impacts of electric vehicles on Indian power grid is motivated to enhance development of electric vehicle in India against the burning issues of rising fuel demand and the nation's dependency on other countries for fuel which largely affects the GDP of nation. India has declared E-mobility mission plan to deploy 4,00,000 passenger electric vehicles by 2020. If this target is achieved India can avoid importing 120 million barrels of oil and avoid 4 million tonnes of CO 2 emissions by 2020. In future, as demand of electric vehicles increases, charging issues while connecting electric vehicle to grid also increases. This paper presents various aspects in terms of challenges and issues when electric vehicle is charged from grid and also the benefits, potential services and applications of electric vehicle in V2G mode. Effect of electric vehicle penetration on distribution grid is carried out in matlab simulink environment to observe effects on different electrical parameters like dc bus voltage, current, active power, reactive power, harmonics and power factor. Concept of vector control technique for voltage source converter is developed for stabilizing grid against penetration of electric vehicle. Control technique implemented here gives fast dynamic response, reduces harmonics and improves power factor with constant dc bus voltage. Concept shown here will be very useful for fast dc charging of electric vehicle batteries. Battery modelling described with the concept of extracting parameters from manufacturers discharge characteristics gives fast and effective solution and will be useful for not only Li-Ion batteries but also for Ni-Mh and Lead-acid batteries.
