“…The authors in [30] provided a review for integration the transport and smart grid sectors through looking at the management of EVs. In [31] the authors focused on a power system reschedule approach taking into consideration EVs and renewable energy. On the other hand, [32] considered energy storage in addition to renewable energy and EVs and targeted home energy management rather than the commercial sector.…”

The United Arab Emirates is moving towards the use of renewable energy for many reasons, including the country’s high energy consumption, unstable oil prices, and increasing carbon dioxide emissions. The usage of electric vehicles can improve public health and reduce emissions that contribute to climate change. Thus, the usage of renewable energy resources to meet the demands of electric vehicles is the major challenge influencing the development of an optimal smart system that can satisfy energy requirements, enhance sustainability and reduce negative environmental impacts. The objective of this study was to examine different configurations of hybrid renewable energy systems for electric vehicle charging in Abu Dhabi city, UAE. A comprehensive study was conducted to investigate previous electric vehicle charging approaches and formulate the problem accordingly. Subsequently, methods for acquiring data with respect to the energy input and load profiles were determined, and a techno-economic analysis was performed using Hybrid Optimization of Multiple Energy Resources (HOMER) software. The results demonstrated that the optimal electric vehicle charging model comprising solar photovoltaics, wind turbines, batteries and a distribution grid was superior to the other studied configurations from the technical, economic and environmental perspectives. An optimal model could produce excess electricity of 22,006 kWh/year with an energy cost of 0.06743 USD/kWh. Furthermore, the proposed battery–grid–solar photovoltaics–wind turbine system had the highest renewable penetration and thus reduced carbon dioxide emissions by 384 tons/year. The results also indicated that the carbon credits associated with this system could result in savings of 8786.8 USD/year. This study provides new guidelines and identifies the best indicators for electric vehicle charging systems that will positively influence the trend in carbon dioxide emissions and achieve sustainable electricity generation. This study also provides a valid financial assessment for investors looking to encourage the use of renewable energy.

“…• It has been demonstrated through experimentation that efficient management of the charging and discharging of PEVs would significantly contribute to mitigating the negative impact on energy system stability that is caused, for instance, by the intermittent production of wind energy. This results in a more effective usage of RERs across longer time periods, which contributes to the creation of an environment that is ideal for generating sustainable energy in the very near future (Zhao et al 2022).…”

“…Because of this, there has been a major reduction in efficiency throughout both the functioning of the grid as well as its administration. As a result of this, the scheduling of variable energy systems has become essential for managing intermittent REGs and the widespread implementation of PEVs (Zhao et al 2022).…”

Can electric vehicles be an alternative for traditional fossil-fuel cars with the help of renewable energy sources towards energy sustainability achievement?

The use of conventional fossil-fuel vehicles in the transportation industry contributes to climate change. The energy producing sector has actually adjusted its strategy to utilize more renewable energy to satisfy the energy demand as a result of this change in strategy. The use of electric vehicles (EVs) in the transportation network has also helped to reduce pollution from the energy industry. However, the distribution network would be placed under a lot of stress if a lot of EVs are attached to it, which might cause a number of problems and worries. However, several initiatives have been made in this direction to help find answers to these issues. The contribution of this review article is that, a number of the benefits of using the employed EVs techniques for the purpose of utilizing renewable energy sources (RESs) towards the accomplishment of a sustainable energy goal for a green environment in the so foreseeable have been highlighted; aiming to provide a larger variety of readers insights and suggestions for future research development. There have been a number of studies that have recommended various ideas and strategies for a reliable renewable energy supply. Their findings have been published in scientific journals. But the relationship between RESs and EVs in terms of energy efficiency is still needed to be further investigated to shorten such a gap in order to assess how EVs can help RESs achieve energy sustainability. Besides, the purpose of this study is to identify and assess the most recent advances and methodologies in the field. It's been possible to use numerous EV technologies to help with various problems and challenges, including the need for quick EV charging stations. However, there is a worry over the viability and applicability of EV-applied technologies that are ideally suited towards greater and more efficient usage of RESs in order to either attain or contribute to energy sustainability. In this article, we will discuss a variety of EV technologies that have been used in the past and contributed to the development of RESs. The method has applied the PRISMA 2020 strategy for inclusion and exclusion criteria. Also, the method has used specific keyword related to the topic including "electric vehicles" and "renewable energy sources". It is found that EVs can be an effective alternative for currently used fossil-fuel vehicles due to a set of reasons highlighted in this review including fast EV charging stations, efficient design for PV solar panels, and effective utilization of RESs.

“…China's "14th Five-Year Plan" further proposes that during the "14th Five-Year Plan" period, carbon dioxide emissions per unit of GDP should be reduced by 18%, and by 2025, the proportion of non-fossil energy in total energy consumption will increase to about 20% (Gong et al, 2022). From the perspective of the power system 10.3389/fenrg.2022.977013 (Zhao et al, 2022), the construction of a new power system with new energy sectors as the main body has become the development form of energy power in the future, and the high proportion of new energy integration brought new challenges to the flexible operation of the power system (Huang et al, 2020). At the same time, electric vehicles (Flah et al, 2021;Mohamed et al, 2022) have received strong support from different countries and governments for their use of cleaner energy, lower maintenance costs, and higher energy efficiency (Li and Hu, 2021).…”

Due to the considerable number of electric vehicles and the characteristics of energy storage, it is possible for these new energy factors to participate in the operation and regulation of the power system and provide reserve service. In view of this, a multi-objective optimal scheduling model is established, aiming at the economic benefits of electricity collectors, the microgrid power fluctuations, and user satisfaction. Among them, the expression paradigm of user satisfaction is proposed. At the same time, an improved adaptive non-dominated sorting genetic algorithm (NSGA-III-W) was proposed to solve the problem of large-scale and high-dimensional multi-objective in the model. First, an adaptive T-crossover operator is proposed to increase the search and optimization capability of NSGA-III. Second, an adaptive crossover mutation mechanism is proposed to improve the convergence performance of the algorithm. In addition, a compromise solution is selected from the obtained Pareto-dominated solutions through the distance ranking method of superior and inferior solutions (TOPSIS). The improved NSGA-III algorithm, namely the NSGA-III-W algorithm, is compared with the mainstream intelligent optimization algorithms non-dominated sorting genetic algorithm II (NSGA-II) and decomposition-based multi-objective evolutionary algorithm (MOEA\D), and the simulation results demonstrate the feasibility of the proposed model and the effectiveness of the proposed algorithm.
