In this paper, a component-based modelling methodology is applied to the commercial load sector. This approach allows for greater insight into the temporal variations in the electrical characteristics of the commercial load sector than currently available modelling practices. This is illustrated by analyzing the half hourly changes in the voltage dependency of the demand and harmonic distortion of a generic UK commercial load sector representation; however, the methodology can be applied wherever similar datasets exist. The results highlight differences between on-peak and off-periods, and provide a useful starting place for probabilistic model development.

This paper proposes a discontinuous modulation strategy of an isolating DC-DC converter on the photovoltaic plant side to reduce the grid side inverter DC link voltage fluctuation. Cascaded H-bridges (CHB) can be used to connect a photovoltaic plant directly to a medium voltage grid without a grid frequency transformer, as the topology has an inherent requirement of having an isolation between the series connected cells. Cascaded H-bridges has a feature that the DC link voltages of the cells have a voltage fluctuation at twice the output frequency. This fluctuation can be reduced by limiting the power towards the capacitor during intervals when the output power is low. The effect of discontinuous mode interval length on the photovoltaic side is studied. The benefits of the proposed method are reduced switching losses at the isolating DC-DC converter and reduced switching losses at the grid inverter due to smaller peak voltages of the DC links.

The paper presents a dual analysis of a permanent magnet synchronous machine (PMSM) designed for an electric power steering system (EPS) used in the automotive industry. Preliminary, the existing PMSM is studied using finite element analysis (FEA) in order to check flux linkage, flux density, cogging and electromagnetic torque values for different speed and current values. Structural design dimensions of the machine are given in detail in the paper as well as FEA based identified parameters used in the real-time analysis. The latter is accomplished using two field programmable gate array (FPGA) processors, each mounted on one Rseries platform, hardware tools provided by National Instruments company. One is running the analytic model of the PMSM with the parameters extracted from FEA and the second one is running the field oriented control (FOC) of the machine. The communication between the two platforms is accomplished using analog and digital IOs to mimic the behavior of the physical test bench with a real machine. Hence, the 3-phase currents are acquired using analog inputs, the position is acquired using digital lines and the PWM is sent via other 3 digital channels. Separation of the machine and converter model on one FPGA and the FOC on the second one, minimizes the gap between testing the real machine and the realtime model in the loop (RTMiL) engaged in this study. Comparative analysis of the FEA and RTMiL results will prove the accuracy of the FPGA based modelling of the PMSM and its control

This paper deals with the bearing wear and the early detection of possible damages in bearings of variable-speed, converter-fed electrical motors. A description covering the issue of bearing currents in converter-fed drives is presented. However, this work focuses on the practical experiences of bearing wear influence on electric motors performance. Explicit information concerning a bearing damage due to corrugation caused by electrical currents through the bearing can only be extracted by a combined analysis of the electrical and the mechanical behavior of the bearing. For this purpose systematic measurements have to be exploited, where both the electrical measurement of bearing currents and the mechanical measurement of the bearing vibration status have to be combined for determining the bearing condition state. A comparison between different vibration measurement methods provides a systematic approach enabling detection and classification of possible changes in bearings of the drive system i.e. motor and the attached load machine, in a very early state. Finally, a description of the possibilities to determine the electrical bearing load in a drive system and the correlation of its possible limit values to the mechanical bearing condition is highlighted.

Combined heat and power (CHP) units are popular generating plants in modern energy systems, especially in the industrial environment. Due to increasing energy expenses and decreasing production cost for CHP units, those became also interesting for residential applications. This paper contributes to this research field by introducing a holistic system design including the control strategy and a superordinate energy management. In residential applications, there are no financial sustainable CHP units available if the peak power demand should be provided by the CHP unit. A cheaper approach could be to integrate an electrical storage system, which is investigated in this contribution. However, it was revealed that profitability cannot be reached according to actual price ranges of batteries and electricity. So, coupling a CHP unit with an electrical storage system is only useful if autarky is explicitly requested for example in rural applications.

Up to few years ago, one of the main problems in the optimal design of a battery energy storage system (BESS) was the availability of both the generation (e.g. renewable sources) and load power profiles of the considered plant. This paradigm has limited the potential of BESSs to drive down overall energy costs and reduce carbon emissions. Nowadays, the exponential growth of data available on the industrial plants has opened the way to new possibilities and opportunities. In addition, BESSs are a viable opportunity to start transforming existing plants with an incremental hybridization of the plant topology. In light of the above, this work develops a commissioning tool that, starting from the data collected on the field, provides the final users the optimal dimensioning of any BESS - according to the taraet performances required bv the specific application.

In this paper the discrete realization of MRAScCestimator of the induction motor speed is analyzed. The influence of the type of the discretization method on the stability range of this estimator is tested. Three most popular discretization methods have been taken into account: the forward and backward Euler methods and the Tustin method. The influence of the discretization step is tested and the speed limit for the estimator stability is determined. Entire analysis is validated by simulation results in wide range of speed variation of induction motor drive, which was controlled by a field-oriented method, for various values of the discretization step.

The paper presents the main results of a study which is dealing with the use of the virtual reality (VR) concept employed for the study of an electric vehicle (EV). The VR study is important before the real implementation of the autonomous-driving of the EV, since it is more efficient and safe to evaluate its operation in a simulation environment. Here, Prescan software is used to develop the VR interface, while Simulink is used to model the entire EV (controller and propulsion unit included). A set of specific sensors can be placed and configured for the autonomous driving in the VR software and the most realistic conditions (i.e., traffic signs and weather conditions, pedestrians, road profiles etc.) can be simulated. It is also possible to program a real control unit via Simulink interface, which is to be used for the supply of a real propulsion motor, via a battery. Thus, the best realistic conditions are evaluated in the VR environment, and thus one could precisely estimate the autonomy of the vehicles in the perspective of evaluating/improving its energy management.

Available peak power of Li-ion battery is crucial index describing ability of consistent energy supply. Among constraints to obtain the index, voltage limit is the most restrictive because of additional voltage drop by impedance. For short time prediction, linear approximation of the open-circuit voltage (OCV) has advantage of simple calculation. However, the prediction of the OCV has large errors especially for the long time interval. Therefore, this paper proposes piecewise-linear model of the OCV for prediction of the available peak power. The simulation and experimental result shows that the proposed method has significantly lower errors than the linear approximation.

Wide Band Gap (WBG) semiconductor technologies such as Silicon Carbide (SiC) and Gallium Nitride (GaN) are considered as the future of power electronic devices. Especially, in hard-switching applications where switching power losses are important, GaN devices are more attractive because of their very low gate charge amount. On the other hand, universal dc-dc power converters in Electric Vehicles (EVs) are coming into attention to be replaced with two power electronic modules: dc-dc battery charger and dc-dc traction drive. Unfortunately, current lateral GaN devices are not applicable in high power dc-dc traction drive, neither in universal dc-dc converters because of their limited current rating. As a solution, a two-phase dc-dc converter is proposed in this paper in which one phase is SiC-based MOSFET and the other one is GaN-based transistor. To reach the maximum utilization of the GaN device, the output power will be shared through the two phases, based on the current rating of the GaN device. First, the power stage design and the average model of the converter are presented. Then, power losses and efficiency of the converter is investigated in comparison with an all-SiC converter through spice-based simulations. The simulation results highlight the higher efficiency of the proposed converter.
