Distributed generation (DG) based on renewable energy sources (RESs) as well as electric mobility and battery storage are currently penetrating electrical energy networks, especially at medium voltage (MV) and low voltage (LV) levels. The energy conversion is mostly based on power electronic devices. The control stability of these power converters is becoming increasingly important as more and more converters are being established in the grids, transforming the grid dynamic response. The Thévenin equivalent (TE) impedance at the point where a converter is connected can be used to represent the grid response seen from the converter. Therefore, an accurate TE parameter estimation is a key enabling feature for high control stability and performance enhancement in smart grids. An analysis of the main sources of TE estimation errors is given in this paper. Focusing on its core mathematical calculation, a new TE estimation algorithm based on least squares fitting for non-linear systems is presented. Simulation results show higher accuracy than a classical linear calculation method, especially at a high degree of measurement errors and reference frame shifts. More accurate TE impedance results can be beneficial for controller optimization of power converters, which will subsequently contribute to the stability of the future power supply systems with high integration of RESs as a whole.

The paper deals with the sensorless control strategy used as a sensor backup for safety-critical applications. The sensorless control strategy is realized through a redundant extended Back-EMF observer structure applied to an asymmetrical six-phase permanent magnet synchronous machine (PMSM), controlled by a standard field-oriented control. A simplified vector space decomposition approach has been implemented to eliminate the current unbalance between two sets of three-phase windings. Fault-tolerant sensorless control strategy has been proposed in this paper for the case of open phase fault. Experimental investigation on a 1kW dual three-phase PMSM drive confirms the feasibility and effectiveness of the redundant sensorless control solution.

This paper presents an energy management strategy for a battery-based stationary energy storage system (BESS) capable of supporting the operation of trolleybus power networks while adhering to the DC network's current and voltage requirements, as well as considering the limitation of the C-Rate, to avoid stress on the battery itself. This work also proposes the dimensioning of this BESS and the comparison of different battery capacities based on a Matlab/Simulink-based model able to simulate a one-day operation of the transit trolleybuses. This manuscript illustrates the effect of the proposed management and the chosen battery through comparisons of the voltage and current profiles along the line. The simulation results show an increase in the voltage level and a decrease in the line current along the catenary with the use of the BESS, indicating that the battery can be a solution to improve the operation of trolleybus systems, even though it is not usually used for this type of network.

Safety-critical applications demand high levels of reliability and fault-tolerance from an electrical machine. In order to fulfill these requirements, the change from three-phase to multi-phase systems and the preferred use of permanent magnet synchronous machine is shown in ongoing research. In this paper, a comprehensive assessment of internal short-circuit faults is conducted on a nine-phase permanent magnet synchronous machine. A machine model including the considered short-circuit faults is implemented using finite element method to analyze the system behavior. Voltage, current, and torque characteristics are used for the analysis.In general, the assessment of different internal short-circuit faults shows that the impact of the fault rises with an increasing amount of shortened turns. The location of the short-circuit fault is also identified to have remarkable impact on the severity. Especially the currents in the affected phase exceed the nominal values, but increasing currents are also seen in the healthy phases. The star-connected (1x9)-phase machine has lower current peaks and torque ripples than the separately supplied (9x1)-phase machine. However, a major disadvantage of the (1x9)-phase machine is the electrical dependency among the phases. This leads to an imbalanced system once the short-circuit occurs. In contrast, the (9x1)-phase machine shows a lower impact of the fault on the remaining phases and a greater potential for future fault-tolerant control strategies.

Fundamental electromagnetic design aspects of high temperature superconductor excited high-speed homopolar inductor alternators are discussed by means of an equivalent 2D FEM model. The proposed model is applied to an exemplary machine with rated power 120 kW at 30000 rpm and makes use of jump periodic boundary conditions in order to impress the homopolar excitation field. The covered design aspects comprise different stator winding topologies, the magnetisation characteristic of the solid rotor material and the pole count.

The theory presented in this paper preserves the inherent symmetry of the matrix converter. In this way, analytically simple and computationally inexpensive formulas are derived to describe the control range and modulation of the classic 3$times$3 matrix converter. No trigonometric formulas need to be evaluated to verify the control range and to calculate the modulation. This is beneficial for the realization of efficient real-time program code.

In the framework of electric propulsion of waterborne vessels, the selection of the best-preferred energy storage system based on batteries, in terms of gravimetric/volumetric energy density and modularity can lead to a cost-saving and reliable design. In this context, an overlook of some commercial Li-based batteries for water transportation is presented. Furthermore, a ranking process based on a Multi-Attribute Decision Making (MADM) method is applied to support the selection of the best alternative, considering a set of technical attributes along with their weights of importance.

This paper proposes a multi objective design optimization approach concerning sensorless performance and torque ripple for Permanent Magnet Synchronous Machine. Sensitivity analysis of design parameters has been accomplished for critical parameters selection and metamodels are generated based on critical variables. Based on these metamodels, the optimization process aims to propose a machine geometry to improve sensorless performance without compromising torque ripple and average torque. The metamodel assisted optimization process has been proved to reduce computational cost with a good accuracy. The selection of the optimal solution was achieved based on multi-objective optimization process using NSGA-II. The optimal solution is validated by finite element analysis and has proved an extending of 100% of the feasibility area of sensorless control with only an increase of 3% of torque ripple.

A new monitoring strategy for PI slip control in an autonomous electric vehicle with two independent in-wheel motors is presented. The distributed motors are employed to regulate the longitudinal speed and yaw-rate. Based on such regulation errors, each motor is given a suitable tire-slip/angular-speed set point. To drive independently each motor to its reference speed, the individual control loops lead to the online steady-state estimation of each actual wheel load-torque which is compensated. Simultaneous information on each tire torque-slip pair allow for a steady-state monitoring of tire operations on force-slip characteristics. An automatic longitudinal speed reduction action is performed to prevent tire forces saturation. An experimental setup is designed on a 1:10 scale autonomous vehicle equipped with 2-rear in-wheel DC brushless motors, aiming to show the reliability of such tire operation monitoring from rear wheel speed real measurements, conditioned by a Kalman filter. A path-following algorithm is developed for the autonomous guidance. The experiment illustrates the automatic speed reduction when the vehicle encounters an adherence jump.

In this paper, the stabilization of the voltage at the output of Boost converters is studied using a switching control method developed in the field of switched affine systems. This control law uses the instantaneous model instead of the nonlinear average model of the converter and has certain advantages compared to traditional approaches. Despite these advantages, the closed-loop system suffers from the occurrence of sliding modes, leading to unacceptable rises in the switching frequency. An adaptation of this control law is proposed in this paper to overcome this problem, and the adopted strategy is based on the introduction of hysteresis in the switching law. Moreover, the extension to Boost converters in parallel is also shown, with the attractive property of each converter only needing local measurements for global stabilization of the system. A comparison with the hysteresis current control method is conducted in simulations.
