Special Issue Information

Dear Colleagues,

Electric vehicles (EVs) are becoming increasingly popular as a sustainable mode of transportation, capable of enabling an effective green transition when integrated in renewable-fed smart grids. In this framework, energy storage systems (ESSs) have become crucial in helping to manage the variability of power production from renewable energy sources and in allocating energy for high power loads (such as EV charging stations), ensuring a stable and reliable electricity supply. Proper modeling and power flow control are still open issues requiring particular attention that can be optimized based on factors such as energy demand, electricity prices, and grid capacity.

Power network interfaces with EVs and ESSs through power converters, which effectively drive the whole infrastructure. As technology continues to advance, their architecture and control algorithms play a crucial role in the future development of the grid. Furthermore, their diffusion reveals the need to also consider electromagnetic compatibility (EMC) issues, both on individual devices and on the smart grid, in which the aggregation of disturbances can compromise the functioning of the network itself.

The design of EV chargers and ESSs and their integration into the electric infrastructure must therefore be addressed with awareness of the power system architecture, as well as control and electromagnetic compatibility issues, ensuring the transition towards a more sustainable and resilient energy system.

The topics of interest include (but are not limited to) the following:

  • Power electronics converters for EV charging and ESSs;
  • EV supply equipment architectures with renewable generation and ESSs;
  • Harmonic pollution, supraharmonics, and electromagnetic compatibility in EV supply equipment;
  • Power quality in AC and DC smart grids;
  • Wireless power transfer (WPT) chargers of EVs;
  • EMC issues in WPT systems;
  • Hybrid and second-life batteries in ESSs used for EV charging;
  • Optimized and collaborative control algorithms;
  • Operation modes for electric mobility (e.g., G2V and V2G);
  • Reliability and fault-tolerant power electronics converters in smart grids;
  • Decision, energy control, and demand response of EV in smart grids.

Energy management for hybrid electric commercial vehicles, involving continuous power output and discrete gear shifting, constitutes a typical mixed-integer programming (MIP) problem, presenting significant challenges for real-time performance and computational efficiency. To address this, this paper proposes a physics-informed neural network-optimized model predictive control (PINN-MPC) strategy. On one hand, this strategy simultaneously optimizes continuous and discrete states within the MPC framework to achieve the integrated objectives of minimizing fuel consumption, tracking speed, and managing battery state-of-charge (SOC). On the other hand, to overcome the prohibitively long solving time of the MIP-MPC, a physics-informed neural network (PINN) optimizer is designed. This optimizer employs the soft-argmax function to handle discrete gear variables and embeds system dynamics constraints using an augmented Lagrangian approach. Validated via hardware-in-the-loop (HIL) testing under two distinct real-world driving cycles, the results demonstrate that, compared to the open-source solver BONMIN, PINN-MPC significantly reduces computation time—dramatically decreasing the average solving time from approximately 10 s to about 5 ms—without sacrificing the combined vehicle dynamic and economic performance.

The energy transition toward greater electrification leads to incentives in public transportation fed by catenary-powered networks. In this context, emerging technological devices such as in-motion-charging vehicles and electric vehicle charging points are expected to be operated while connected to trolleybus networks as part of new electrification projects, resulting in a significant demand for power. To enable a significant increase in electric transportation without compromising technical compliance for voltage and current at grid systems, the implementation of stationary battery energy storage systems (BESSs) can be essential for new electrification projects. A key challenge for BESSs is the selection of the optimal converter topology for charging their batteries. Ideally, the chosen converter should offer the highest efficiency while minimizing size, weight, and cost. In this context, a modular dual-active-bridge converter, considering its operation as a full-power converter (FPC) and a partial-power converter (PPC) with module-shedding control, is analyzed in terms of operation efficiencies and thermal behavior. The goal is to clarify the advantages, disadvantages, challenges, and trade-offs of both power-processing techniques following future trends in the electric transportation sector. The results indicate that the PPC achieves an efficiency of 98.58% at the full load of 100 kW, which is 1.19% higher than that of FPC. Additionally, higher power density and cost effectiveness are confirmed for the PPC. Full article
