“…One method that has been utilized for charging EV batteries is the installation of stationary energy storage systems. Sometimes, this energy storage system comes with a renewable energy source or another energy storage device to increase the charging system's reliability (Sabzi, Asadi, and Moghbeli 2019;Sabzi, Asadi, and Moghbelli 2017;Sabzi, Asadi, and Moghbelli 2016;Moghbelli and Sabzi 2015). Figure 6 shows a simple diagram of such a system.…”

Over the past years, electric vehicles (EVs) have attracted great attention worldwide. Using EVs helps reduce CO2 emissions and the use of fossil fuels and motivates the nations toward a more sustainable future where the consumed energy matters. EVs are the main part of E-mobility; therefore, the EV integration problem is very important. This paper discusses the importance of EV integration in smart grids, and challenges toward the electrification of future cars are investigated. The two main categories for challenges are security and utility-related challenges. Security challenges deal with the communication means in the e-mobility, while grid-related challenges correspond to the energy that must be supplied and delivered to the vehicles. Security challenges come from the devastating actions from outside threats such as hacks, but the grid-related challenges come from the system's nature and can be dealt with using physical and software-based methods. While the challenges of security and grid are investigated, since our future work focuses on energy and cost optimization, the solution of grid-related challenges will be covered.

“…Therefore, the derivatives of reference values are zero and can be neglected in further calculations. Substituting (6) and (15) into (17), Lyapunov function's derivative form is calculated as (18) in which some terms (such as ÀR uc x 2 1 ) are always negative and neglected and some are simplified. Furthermore, d 3 and d 12 must be calculated in a way that (18) stays negative and system remains globally stable, therefore:…”

In recent years, urban rail systems have developed drastically. In these systems, when induction electrical machine suddenly brakes, a great package of energy is produced. This package of energy can be stored in energy storage devices such as battery, ultra-capacitor and flywheel. In this paper, an electrical topology is proposed to absorb regenerative braking energy and to store it in ultracapacitor and battery. Ultra-capacitor can to deliver the stored energy to DC grid and to charge the battery for auxiliary applications such as lighting and cooling systems. The proposed system is modeled based on large signal averaged modeling, which leads to the simplicity of calculations. The control system is based on Lyapunov stability theorem which guarantees system stability. Also, an energy management algorithm is proposed to control energy under braking and steady-state conditions. Finally, the simulation results validate the effectiveness of the proposed control and energy management system.

This paper offers a literature review on different structures and control strategies of the microgrid. The implementation of a microgrid system provides significant advantages for both electric utility and end-users. Microgrid control is one of the most sophisticated parts of such implementations that must be taken into account before moving to the next steps. The different control objectives and structures of the main grid and microgrid lead to various control methods proposed for microgrids. The hierarchical structure is the most accepted method for microgrid control that has three levels including primary, secondary, and tertiary. The focus of this study will be on the main modes of typical microgrids, types of microgrid and how to control them. The investigation of this paper will give an overview to the readers, and in our next paper, we will focus more deeply on the subject, with a specific concentration on the concept of secondary control and corresponding trending methods.
