Summary: The increasing popularity of electric vehicles has led to a demand for better charging infrastructure, with ultra-fast charging technology playing a key role in enabling long-distance travels. The differences in EVs on the market make the sizing of charging stations more challenging, but a smart charging strategy can help address these issues. By modeling the optimization of charging stations as a single-objective problem, it is possible to reduce the required installed power significantly while meeting the needs of multiple charging spots effectively.

Summary: This paper investigates two methods, phase reconfiguration and phase-specific control, to address congestion issues in charging sites. Extensive simulations show that these methods have the potential to increase charging energy and improve the quality of charging service, particularly in highly congested sites. The results also indicate the greater benefits of phase-specific control in congested sites, and discourage the use of perfectly balanced three-phase loading assumption in future studies.

Summary: One way to encourage the usage of electric vehicles is to reduce the connection time by using higher-powered charging points at home. However, this could stress the grid beyond its limits. Therefore, it is important to assess the increase in power demand and find ways to minimize it. An EV charging coordination model is developed to compare the impact of slow and fast-charging plans on system demand. The results show that coordination can effectively manage the aggregate effects of fast-charging events.

Summary: The demand for electric vehicles and EV charging has significantly increased in the past decade. This study aims to develop a stochastic dynamic simulation modeling framework for a regional system of EV fast-charging stations, investigating the impact of dynamic demand-responsive price adjustment (DDRPA) schemes on charging demand. The results show that DDRPA strategies are effective in balancing charging demand across fast-charging stations.

Summary: The sustainable evaluation of energy sources for EV charging stations is crucial. We propose a model based on R-numbers and combined compromise solution method (R-COCOSO) to assess the sustainability of these stations. We also developed the CODAS method based on R-numbers to evaluate project risk, and a linear programming model to optimize workload allocation and contractors' risk response based on R-numbers and the epsilon-constraint approach. A real case in Tehran, Iran, was used to validate the accuracy of the model.
