The ever-rising number of grid-connected inverters contributes to an increase of DC current injection into utility grid, resulting in the saturation of distribution transformers, metering errors and the corrosion of earthling conductors. A transformerless single-stage Z-source inverter uses only two switching devices in its converter circuit to generate sinusoidal voltage as that of a full-bridge inverter. However, this inverter has the problem of having a DC offset in the AC waveform due to the presence of steady-state error when the modulation index is varied. The paper proposes a Proportional-Resonant (PR) control scheme to eliminate this DC offset. By comparing Z-source inverter output voltage with the sinusoidal reference voltage obtained from the sinusoidal control signal, an error signal is obtained which is fed into the PR controller. An infinite gain at the fundamental frequency is introduced by the PR controller, thus achieving zero steady-state error resulting in the elimination of DC current injection into the utility grid. This method does not depend on high-precision current measurement or the use of coupled inductors. Also, this method can be used to improve power quality by providing reactive power compensation to the load at the point of common coupling. Simulation results are presented to confirm that this simple, cost-effective method can be used to eliminate DC current injection for different values of modulation index without compromising the dynamic response of the current feedback loop

The modern power system encounters difficulties in increasing the share of renewables as they are not participating in the total power system inertia, which endangers the strength of the power system against faults. As conventional generation with inherent inertia provision ability are being replaced by converter-based generation, they have to perform this role. Therefore, it is important that the control method of wind turbines seamlessly estimate frequency variation and be designed to make the inertia power command to smooth it. Hence, in this paper, inertia provision in an islanding scenario in a power system by a wind turbine will be studied. The inertia is provided via rotating masses or auxiliary power source, or together in a two-step inertia power injection. The power and energy limitations will also be considered in the comparison of inertia provision in different scenarios. The time is important for the injected inertia power to catch the frequency from falling into a very low nadir and make a different stability border for the share of renewables. In this study, the effect of converter-fed loads will also be investigated.

Single-phase voltage-source converters are widely used in power conversion systems like grid-interfaced photovoltaic arrays. This paper presents a control method for the single-phase inverter that is looking to reduce the harmonic content of the output voltage, especially for the situation when the inverter feeds a crest-factor load. In this case, the currents are non-sinusoidal and relatively distorted; as a result, the THD is higher than the specification allows. The method proposed uses a voltage controller followed by a current controller - both are implemented in the stationary reference frame. The voltage controller uses a harmonic elimination method based on modulation-demodulation. This approach regulates the fundamental of the voltage and is also used to attempt the elimination of some higher order harmonics. In the simulations and experiments shown in the paper, the regulation and harmonic elimination scheme is implemented for the fundamental and for the 3rd, 5th and 7th harmonics of the voltage. The scheme can be expanded further to eliminate the harmonics of even higher order. It is shown that the control method proposed significantly reduces the Total Harmonic Distortion (THD) of the output voltage, from 5.8% (at full load, uncompensated) to 1.6% (at full load, with compensation). The control method proposed is validated with simulations and experimental tests.

The objective of this paper is to increase the reliability of DC-DC converters operation, used in DC Microgrids (MG). This paper will determine the design requirements for a Sensor Fault Diagnosis (SFD) strategy for a DC-DC converter intended for DC MG, in order to allow continuous operation during erroneous sensor measurements. The SFD scheme is based on residuals generated by a generalized observer scheme. The observer gains is based on adaptive high-gain observer theory. The generated residuals are compared with thresholds, to detect sensor faults. The SFD scheme for the Line Regulating Converter (LRC) side is validated through simulations on a prototype DC MG system where the sensors are subjected to three types of sensor faults. In this paper, the prototype DC MG system will consist of a battery which is connected to the DC bus through a bidirectional buck/boost converter. A buck converter is used as LRC connected to the DC bus.

Fault detection and isolation (FDI) strategies can be implemented to increase reliability and prevent faults of power switches from disrupting converter operation. This is especially important for Modular Multilevel Cascade Converters (MMCC) due to the high number of switches employed in this topology. This paper proposes a new model for chopper cells, the core component of an MMCC. Unlike reported methods, the proposed model enables open-circuit fault detection and excellent tracking of cluster currents using a Sliding Mode Observer (SMO) under normal and faulty operation. The model has been successfully validated to detect faulty operation by using PLECS simulations in a BTB MMCC-DSCC.

This paper presents a generic switching state-space model for modular multilevel cascade converters in double-star connection (MMCC-DS) which can either be used with chopper cells (CC; half bridges) or bridge cells (BC; full bridges) and allows to consider arbitrary switch(ing) faults. The output terminals of the MMCC-DS are connected to a general resistive-inductive (RL) load with additional voltage sources in star connection. The model is derived and described in detail by using Kirchhoff's current and voltage laws (KCL, KVL) and allows for currents flowing through the anti-parallel diodes of the active switches in each cell. The model is implemented in Matlab/Simulink 2019b and PLECS for a simulative validation and comparison of the proposed model.

The multi-parallel chopper system is commonly used in modern MW-level wind turbine converters. Even though the chopper is usually considered as robust and reliable, the semiconductor module can suffer critical junction temperature in extreme fault ride through (FRT) events. This paper proposes a method to monitor and identify if the individual chopper is functioning, degraded, or failed by means of collecting and comparing the parallel semiconductors' temperatures during FRT events. A simulation model is created in PLCES, the accuracy of which is further validated by a dedicated experimental setup including an infrared camera. The proposed method is verified by PLECS simulations.

In small–scale power systems, distributed virtual inertia (DVI)–based converters can effectively participate in primary frequency regulation. In this method, the synthetic inertia provision is fulfilled by discharging the preserved energy of dc–side capacitors employed in grid–interactive converters. Nevertheless, the eigenvalue analyses provided by small–signal state–space model of the converter reveal that the DVI function induces instability to the converter operating in weak grid connection. To address this issue aimed at improving grid frequency stability during frequency events, a new compensator is presented in this work. The compensator is designed so as eliminates the negative effect of DVI regulator on system stability. The effectiveness of proposed approach is illustrated by the time–domain simulations in MATLAB. The results show that the frequency rate of change following a frequency perturbation is enhanced by 40.38% compared with the scenario in which the synthetic inertia functionality is nullified.

The three-level T-type multilevel inverter has proven itself as a promising, highly-efficient, and low-switch-count topology. This paper presents a new topology configuration using series connected T-type multilevel inverters for medium-voltage applications. The proposed topology utilizes the series connection of low power T-type modules to enable medium-voltage operation. The proposed topology is modular, highly efficient, less complex, and with lower component count, compared to other topologies with the same number of levels and voltage operating range. In addition, a simple level-shifted pulse width modulation (LS-PWM) method is proposed for achieving voltage balance between the dc-link capacitors. The results show the effectiveness of the proposed topology and the proposed LS-PWM method for medium-voltage applications. Moreover, the proposed topology has been compared with the existing medium-voltage converter topologies in the literature.

New electronic power distribution systems built for airplanes, ships, electric vehicles, data-centers, nano- and microgrids dominantly comprise a variety of power electronics converters with very different dynamic characteristics. Other than the information from datasheets, system integrators have no deeper insight into dynamic behavior and interactions between system components before they integrate particular systems. This paper presents a generalized black-box modeling method of three-phase inverters, rectifiers, motors, and generators for system-level study and on-line stability assessment. Especially interesting for OEM, this methodology allows equipment manufacturers to provide behavioral models of their components without disclosing proprietary information such as topology, structure, control loops parameters, etc., while system integrator can truly benefit from using these models for their (better) system-level design.
