Special Issue Information

Dear Colleagues,

The next energy transition calls for a more electric world, thus posing new challenges to the research community in terms of achieving the goal of decarbonized power systems. In this context, innovative solutions for power converters, electrical machines, and drives are requested in several application fields: electric mobility, electrical power production from renewable energy sources, and aircraft and ship propulsion.

The ever-increasing penetration of renewables in the utility network poses a challenge with respect to power system architectures and their management strategy since strict grid requirements have to be met despite the distributed and intermittent nature of the energy sources. Moreover, the exploitation of the electric drives is quickly expanding from railway-based vehicles to road-based ones, thus posing new challenges not only for the design of the electric drives (from the energy storage system to the electric machine) but also for the integration of recharge stations in electric power systems. Additionally, the aircraft application field represents another challenge, in which there is a demand for more electric aircraft (MEA) to push toward the concept of all electric aircraft (AEA), leading to the substitution of traditional actuators (e.g., pneumatic, mechanical) with electric-based ones. Even advanced hybrid ship propulsion configurations are being investigated with the aim to make such systems, which currently have a strong impact on world pollution, more environment friendly. In all applications, storage systems play a key role in adding more flexibility to power architecture by ensuring a suitable energy management.

Therefore, this Special Issue serves to address the challenges and issues arising from energy transition, particularly by proposing new solutions for the design and control of power converters, electrical machines, and drives. Topics of interest for publication include but are not limited to:

  • Electric drives for transportation;
  • High-efficiency power converters for high-speed electric machines;
  • Modeling and design of high specific power electric machines;
  • Multiphase configurations of electric machines;
  • Fault-tolerant electric drives;
  • Control strategies for post-fault configurations in electric drives;
  • Power systems for renewable energy resources;
  • Energy storage systems.

The paper deals with a grid-connected single-phase battery charger integrated with photovoltaic generators (PVGs). The circuit topology consists of a multilevel architecture based on a Cascaded H-Bridge (CHB) rectifier. Its main task is to charge the batteries, primarily from the PVGs, by also assuring to keep their state-of-charge (SOC) balanced. Nevertheless, when the battery SOC overcomes a predefined upper limit, beyond which the charging process could be interrupted, the available PV power can no longer be transferred to the batteries. Therefore, to avoid an undesired curtailment of PV power production, this latter can be supplied to the grid by inverting the system operation. The paper shows how to achieve this result by implementing a dedicated control action based on a multi-step procedure. Numerical investigations are carried out on a 19-level CHB converter implemented in the PLECS environment to validate the feasibility and effectiveness of the proposed control technique. Full article

The paper is focused on the formalization of an experimental procedure aimed to characterize the efficiency behaviour of a Permanent Magnet Synchronous Motor-based drive. The characterization is intended to expose the analytical behaviour of the system efficiency by the actual operating condition assigned through torque/speed value. The availability of such a relation in a simple analytical form would allow for real-time adjustment by advanced power management strategies to maximize the whole system efficiency. The proposed method is based on a defined set of measures corresponding to several drive operating conditions. A straightforward elaboration procedure is then formulated with the aim to quantify the different parameters, which intervene in the efficiency characterization. The method has been applied on a 155 kW drive. The results show that good accuracy is achieved while keeping the analytical approach relatively simple. Full article
