The energy sector is more and more characterized by the spread of distributed generation, energy storage systems, and smart electric mobility. In many countries, renewable energy sources (mainly solar, hydro, and wind) represent a significant share of the national energy mix, and the power system architecture has deeply changed, moving from centralized energy production to decentralized production. Innovative smart grid and microgrid projects have been developed and implemented in different sectors, such as industrial areas or sustainable urban districts. Moreover, the electric mobility sector has recorded fast growth in terms of full-electric and hybrid vehicle sales and installation of chargers. Challenging initiatives related to safe and efficient applications of electric vehicles, as well as to the implementation of smart charging and V2G (vehicle-to-grid) and V2B (vehicle-to-building) technologies have been conducted too. Both renewable power plants and electric mobility infrastructures interact with power networks. The impact of the aforementioned technologies on the power system has to be investigated taking into account technical and economic aspects as well as standards and the current legislative framework. In addition, technical merits in energy storage systems, such as batteries and super/ultra-capacitors are critical for the success of transportation electrification and to foster the utilization of renewable energy sources. This Special Issue will present the research activities focused on the analysis of the impact of electric mobility on power grids, with a particular focus on the interaction of electric vehicles and charging infrastructures with distribution networks and smart grids and microgrids. Moreover, special emphases are given to the design, modeling, management, control, and safety enhancement of energy storage systems, such as batteries, super/ultra-capacitors and fuel cells applied in transportation systems. In particular, we invite the submission of papers addressing issues related to the analysis, simulation, and optimization of both energy storage systems in electric vehicles and electric mobility systems in sustainable grids and microgrids characterized by the presence of renewable power plants and V2G and V2B technologies.
