“…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.

“…Lyapunov function can be found by state space variables. According to Lyapunov's stability theorem, a nonlinear system is globally asymptotically stable, if the selective Lyapunov function satisfies the following properties [40, 41]:

\{\begin{matrix} V ((), 0) = 0 \\ V ((), x) > 0; f o r a l l x \neq 0 \\ \overset{V}{true} ((), x) < 0; f o r a l l x \neq 0 \\ \lim V ((), x) \to \infty; (‖‖, x) \to \infty \end{matrix}

where V ( x ), and x are Lyapunov function, and state space variable.…”

This paper focuses on design of a control system for full bridge DC‐DC converter based on Lyapunov stability theorem which guarantees system stability. To achieve this goal, a full bridge DC‐DC converter is used as a Li‐ion battery charger and sinusoidal ripple current (SRC) is implemented as the charging algorithm. In initial step, state space equation of the system including DC‐DC converter and battery are obtained. After that, switching function is extracted by applying Lyapunov stability theorem to state space equation. Also in order to achieve unity power factor and allowable current Total Harmonic Distortion (THD) range based on standards, an Active Front End (AFE) PWM Rectifier is used. To evaluate the effectiveness of the proposed controller scheme, a laboratory prototype is implemented. Experimental result shows appropriate performance of proposed controller in tracking of reference values in comparison with fixed PI controller. In addition, results of AFE rectifier performance is evaluated by showing the unity power factor and low THD value.

“…Applications: In [210], a sliding mode control strategy was applied to an electric drive in railway regenerative braking energy applications where the strategy was based on Lyapunov stability theorem designed and simulated in order to realize the system stability in all operating conditions. The strategy was applied to a bidirectional DC-DC converter (for charging/discharging the supercapacitor), and a unidirectional for charging the battery from the supercapacitor.…”

<p>Electrified urban railway systems are large consumers of energy in urban areas and thus, there is a need for energy saving measures in this transportation sector. Recuperation of train’s regenerative braking energy (RBE) is one of the best ways for attaining high levels of energy efficiency in this area. Energy Storage Systems (ESSs) prove to be the most practical and viable solution for maximizing the RBE utilization in urban railway systems. In the existing related reviews of ESSs, few papers covered the review of ESS technologies or converter interface. However, a comprehensive review is needed in this regard. This paper discusses an overview of urban railway electrification, and detail review for the three ESS components – ESS Technologies, Bidirectional DC-DC Converters (BDCs), and Controller Unit. This study concludes that among the storage technologies, supercapacitor ESS appears to be the most suitable followed by Lithium-ion batteries and flywheels. For BDC, cascaded BDC is the most suitable followed by dual active bridge. For control methods, fuzzy logic and artificial intelligent are recommended among other control strategies. Thus, the key contribution of this paper is the comprehensive review and analyses of the ESS’s components in the recovery of RBE in urban railways. </p>
