“…The behavior of the electric mobility as a contribution for stabilizing the grid voltage, also considering RES, is presented in [6]. Similar studies can be found in [7], [8], [9], and [10]. Also framing all of these three strands prospecting an economic deployment, a hybrid strategy is proposed in [12].…”

The integration of renewable energy sources (RES), energy storage systems (ESS), and electric mobility into smart grids requires the use of dc-dc back-end power converters for adjusting voltage levels. Although a dc-dc converter applied for RES only operates in unidirectional mode, when applied to ESS or EM, the bidirectional mode is a fundamental requisite for exchanging power with the electrical power grid. In this context, this paper presents an experimental validation of a proposed bidirectional three-level dc-dc converter considering its application for smart grids. Traditionally, the dc-dc power converters of such applications are two-level converters. However, by employing a three-level topology, it is possible to improve the quality of the variables controlled by the power converter. Moreover, since the proposed dc-dc converter is controlled to produce a controlled current, the proposed current control and modulation strategies are introduced and described. A complete analysis of the operation principle of the proposed bidirectional three-level dc-dc power converter is presented, supported by experimental validation, employing a laboratory prototype.

“…Electric mobility is expanding its engagement in the transportation sector, offering several technologies prospecting the sustainability of this area [1], not only in the perspective of the vehicle, but also in the perspective of the power grid [2] [3]. Moreover, the cooperative mixture with renewables prospecting power management for the power grid side can also be seen as a key challenge offered by the flexibility of the electric mobility in terms of random connection to the power grid [4] [5]. In this context, the incorporation in the paradigms of microgrids [6], smart grids and smart cities is of paramount importance [7].…”

The charging process is one of the main factors for the widespread dissemination of electric mobility, therefore, the use of optimized power electronics converters is of utmost importance. In addition to innovative topologies, the use of emerging technologies of semiconductors is also crucial. In this context, using a three-phase interleaved dc-dc topology, a comparison between the use of SiC-MOSFET and Si-IGBT is presented in this paper, mainly in terms of operating efficiency. Two cases have been presented: 1) with the same inductor, where only power device losses have been considered; 2) with the same inductor current ripple, where different inductors have been considered and the analysis included also the inductor design and losses. The simulations were carried out in LTspice simulation tool on realistic dynamic models of power switch modules obtained from the manufacturer's experimental tests. The results validate the use of SiC-MOSFET for the three-phase interleaved dc-dc topology showing lower losses for both the power devices and inductor and, most important, prove the advantages of its use in terms of efficiency for a wide range of operating powers.

“…At the same time, the possibility of forming a coalition between the owners of EVs serving one company and the owners of this company remains unexplored. Such a statement of the problem is important because we assume that a significant number of EVs mainly use two parking spaces [16,30] as follows:…”

Charging and Discharging Scheduling for Electrical Vehicles Using a Shapley-Value Approach

The number of electric vehicles (EV) in the world has been increasing and is gaining momentum. The large-scale use of EVs in public life has initiated the need to establish EV battery charging services within the power system. Currently, EVs serve as a transportation tool and also as a flexible load. This publication examines the possibility of the owner of an electric vehicle choosing a battery recharging point, as well as of the involvement of several decision makers in the selection of a charging schedule. This problem is important because we assume that a significant proportion of EVs mainly use two parking spaces, one located close to the place of residence and another close to the workplace. We accept and prove that a car charging station can be created by the employer (company) and implemented in the best interests of the employer and the employee (EV owner). For that, a coalition between the company and the EV owner has to be formed. To support rational decisions, this study solves the problem using the cooperative game theory and designs a payment distribution mechanism based on the Shapley value. The results obtained prove that the coalition is beneficial under different conditions, which depend on the capacity of the EV, the distance between the workplace and the place of residence, the difference in the electricity prices of the day, as well as the consumption of the company. In order to estimate the coalition’s gain, it is necessary to take into account the structure of the power tariff system for both the company and the EV owner. Furthermore, we prove that the presence of a coalition allows the company and the EV owner to reduce the annual fee for consumed power. The results of this analysis could be adopted by decision makers such as government agencies, companies, EV owners, and they are recommended for potential investors for the development of transport electrification and smart energy.
