Summary: This paper examines the challenges of constructing wireless chargers using inductive power transfer (IPT) technology for megawatt-level marine energy storage systems. The feasibility study uses the MF Ampere ferry as a case study. Calculations and simulations show that multiple low-power (100 kW) IPT systems need to be paralleled to achieve 1 MW power transfer due to voltage and current stress limitations. Two proposed solutions for fast charging at the 1 MW level are presented: 10 units of 100 kW without mechanical mooring assistance or 5 units of 200 kW with mechanical mooring assistance.

Summary: Anatomical realistic voxel models are commonly used in numerical dosimetry to evaluate human exposure to low-frequency electromagnetic fields. However, these models do not accurately reproduce the boundaries of curved surfaces, leading to computational errors. This paper shows that tetrahedral meshes can help mitigate these errors, but the quality of the mesh is crucial. Real exposure scenarios may still result in artifacts even with regular meshes, necessitating the use of filtering techniques.

Summary: Industrial companies are increasingly electrifying their equipment and processes as part of a broader energy transition. Energy efficiency and reducing environmental pollution in internal logistics are becoming competitive factors and research objectives. Wireless power transfer technology offers a contactless solution for reducing battery demand and vehicle downtimes. This study proposes a methodology for determining the optimal positioning of wireless charging units in warehouses, for both static and dynamic recharging. The approach uses a mathematical model and integer linear programming to find the best layout that meets energy requirements and minimizes costs. Testing the optimizer in different warehouse scenarios showed that integrated dynamic and static WPT systems can maintain a constant state of charge for electric vehicles during operation.

Summary: The penetration growth of electric vehicles (EVs) is crucial for reducing transportation-related local pollutants. Most countries are rapidly developing charging infrastructure to accommodate the increasing EV energy demand. However, forecasting power demand for EV charging is challenging due to various factors, such as the limited number of EVs, diverse user behaviors, heterogeneous charging infrastructure and EV population, and uncertainty regarding the initial state of charge (SOC) distribution. This paper proposes a forecasting method that considers all these factors and predicts users' behavior and initial SOC through statistical patterns. Machine learning techniques are employed to develop a battery-charging behavioral model, which accounts for different EV models. The results demonstrate significant differences in power demand across various parking scenarios.

Summary: This paper discusses the issues related to short-circuit calculations in hybrid AC/DC microgrids. The current reference standard for short-current calculations in DC systems does not consider more complex systems such as meshed DC systems or hybrid AC/DC microgrids. To address this limitation, the paper proposes a generalized approach that can be applied independently of the characteristics of the hybrid system. The approach is validated through simulations on two test microgrids and compared with results obtained using Neplan 360.
