With the increasing popularity of electric vehicles, the disordered charging of large-scale electric vehicles will have a great impact on the safe operation of regional distribution network. In order to solve the security problems that may occur in the power grid, this paper uses the time-sharing pricing time division method for EV charging to meet the needs of EV users. Based on this method, a multi-objective optimization model is established, which takes the electric vehicle charging capacity and power as the constraints, and based on the minimum user charging cost and the minimum load curve variance. Then, the model is solved by non-dominated sorting genetic algorithm (NSGA -Ⅱ), and the optimal compromise solution is extracted by using fuzzy set theory. Finally, the correctness of the proposed model is verified by the example.

The research considers various aspects of electric vehicle production in some leading foreign countries. Dynamics of specific weight of electric vehicles in total transport and its forecast indices are under analysis considering those of the countries planning complete transition to electric mobility. Urgency of building an expanded network of charging stations of various capacity is pointed out. It is revealed that Volkswagen, the world largest automobile concern, is going to introduce much more new designs of electric vehicles than it considered before – 70 instead of 50 by 2028. It is planned to produce more electric vehicles – from 15 to 22mln in the decade to follow. Besides, the share of electric vehicles in the concern’s total production is to exceed 40% by 2030. It is indicated that 44bln euros will be invested into designing new VW automobiles in the nearest 5 years. It is significant that in many foreign countries there are subsidies and tax reduction for electric vehicle owners which are used as an important tool of the state’ incentives. Besides, special attention is paid to improvement and development of production of batteries for electric cars, especially in the EU countries. The authors suggest schemes of elaborating electric mobile innovations and power supply for electric mobility providing green and economic solutions for generating power for electric cars by wind generators. Potential production of Ukrainian electric cars is under analysis. It is highlighted that electric vehicle production allows combining two economically beneficial factors – innovative character of a product and its large-scale production. In this case, there will be a novelty effect and huge unsatisfied demand as well as scale saving.

Abstract Electric vehicles are on the rise, but are still far from reaching the global market share required to achieve climate objectives. While financial and technological adoption barriers are increasingly removed, psychological barriers remain insufficiently addressed on a large scale. Here, we show that car owners substantially underestimate the compatibility of available battery capacities with their individual mobility needs, increasing the demand of long battery ranges and reducing willingness to adopt. We test a simple behavioral intervention in two randomized online experiments in Germany and the U.S.: providing tailored compatibility information reduced range anxiety and increased willingness to pay for electric vehicles. Compatibility information more strongly increased preferences than information about privileged access to charging infrastructure, and selectively increased preferences of car owners for whom an electric vehicle would yield higher financial benefits. This scalable intervention may complement classical policy approaches in achieving a resource-conscious and global electrification of mobility.

The large-scale electric vehicles connected to the microgrid have brought various challenges to the safe and economic operation of the microgrid. In this paper, a hierarchical microgrid dispatching strategy considering the user-side demand is proposed. According to the operation characteristics of each dispatch unit, the strategy divides the microgrid system into two levels: source-load level and source-grid-load level. At the source-load level, priority should be given to the use of the renewable energy output. On the basis of considering the user demand, energy storage, electric vehicles, and dispatchable loads should be utilized to maximize the consumption of the renewable energy and minimize the user’s electricity cost. The source-grid-load level can smooth the tie-line power fluctuation through dispatching of the power grid and diesel generators. Furthermore, the study presents a modified MOEA/D algorithm to solve the hierarchical scheduling problem. In the proposed algorithm, a modified Tchebycheff decomposition method is introduced to obtain uniformly distributed solutions. In addition, initialization and replacement strategies are introduced to enhance the convergence and diversity. A wind-photovoltaic-diesel-storage hybrid power system is considered to verify the performance of the proposed dispatching strategy and the modified algorithm. The obtained results are compared with other dispatching approaches, and the comparisons confirm the effectiveness and scientificity of the proposed strategy and algorithm.

With the large-scale EV(electric vehicle) integrating into the power system, new challenges has been brought to the planning as well as the security of the network. There will be a great impact on the system if the system operator ignores the vast quantity of EV charging at the same. Thus, taking measures, e.g. the multiple tariff, is of vital importance to give the guidance to the EV owners to charging wisely to save the daily cost on charging, as well as reduce the gap between peak load and valley load. A model for TOU has been presented in this paper. In the model , an objective function is declared to describe the purpose of TOU, and the optimal solution is gained according to the response of EV when the price of electricity changes. Finally , a case based on the daily load curve of a certain place is calculated with the model in this paper.

Electric Vehicles (EV) are the world’s future transport systems. With the rise in pollutions and its effects on the environment, there has been a large scale movetowards electrical vehicles. But the plug point availability for charging is the serious problem faced by the mostof Electric Vehicle consumers. Therefore, there is a definite need to move from the GRID based/connected charging stations to standalone off-grid stations for charging the Electric Vehicles. The objective of this paper is to arrive at the best configuration or mix of the renewable resources and energy storage systems along with conventional Diesel Generator set which together works in offgrid for Electric Vehicle charging. As aconclusion, by utilizing self-sustainable off-grid power generation technology, the availability of EV charging stations in remote localities at affordable price can be made and mainly it reduces burden on the existing electrical infrastructure.
