The conventional passenger transportation systems powered by electricity require a continuous and reliable power system supply that maintain its regular operation. The electrification systems that drive the vehicle’s electric motors necessitate an external power supply during their operation, leading to technical and economic challenges that result in vulnerabilities potentially affecting the overall performance of these systems.

The current electrification system of the Magnetically Levitated Train (MagLev-Cobra) requires a power bus along its 200-meter test guideway and the continuous connection of brushes throughout its route to provide power supply to the vehicle’s electrical systems.

This paper proposes a solution that involves implementing an energy storage device on board the vehicle, providing it with sufficient autonomy to travel between two stations. This approach eliminates the need for a power bus along the guideway, offering a more efficient and flexible power supply solution.

This work presents a power-based control technique for controlling the battery current in a quasi-impedance source converter (qZSC) topology. Such topology can integrate a photovoltaic (PV) array and a battery storage system (BSS) using a single inverter bridge. However, the control strategies for managing the energy stored in the BSS for this topology are vulnerable to disturbances in the PV power, and have a high level of complexity, especially in terms of mathematical modeling. Therefore, the proposed control method aims to improve this functionality by implementing a cascade control based on the active power between the qZSC and the grid. Therefore, the dynamic model relating the battery current and the qZSC active power output will be demonstrated, as well as the respective closed-loop controller design. The simulation results demonstrate the effectiveness of the proposed modeling and control technique.

One noteworthy solution in the context of more accurate representation of power systems is the use of distributed simulation, such as co-simulation using real-time simulators.

Therefore, the electrical connection between the two distributed systems play an important role within this solution, specially in the stability of the simulation. This paper presents an assessment of the interface algorithms utilized in the literature, presenting the stability of the distributed simulation setup. This methodology was tested with the co-simulation of the well-established system IEEE 9-bus in a real time environment using two OPAL-RT OP5707, and simulation results confirm the proposed analysis.

The main objective of this paper is to discuss the data acquisition of the MagLev-Cobra magnetic levitation vehicle.

The vehicle is located at the Technology Center of the Federal University of Rio de Janeiro. It was inaugurated in 2014 and is the first vehicle of its kind to use superconducting levitation in the world. As in other technological systems, it is extremely important to analyze the magnitudes related to its operation and

efficiency. In this work, the main characteristics of the MagLevCobra are discussed, in addition to the analysis of experimental data of the magnitudes to be sensed.
