Multilevel inverters (MLIs) have made great strides in utilizing renewable energy and industrial applications compared to conventional two-level inverters in terms of output voltage quality, smaller size of the output filter, and higher efficiency. This paper describes a new diode containing bidirectional topology for single-phase MLI. This structure is presented to reduce the count of switches, isolated voltage sources, and drivers that can increase the number of output levels modularly. This converter, despite the use of diodes, can feed bidirectionally the low power factor inductive–resistive loads. The proposed structure has been designed to achieve a higher output voltage levels relative to the number of switches, drivers, and direct current (DC) voltage sources. Three different algorithms have been proposed to determine the values of DC voltage sources. To confirm the superiority of the proposed structure, a detailed comparison has been carried out with other MLI topologies. Then the proposed topology is simulated in Matlab/Simulink environment using the nearest level modulation technique. Finally, experimental results are presented to confirm the performance of the designed structure in symmetric and asymmetric topologies.

Utilization of small-scale wind energy conversion systems (WECS) has been grown in recent years. Permanent magnet synchronous generator due to lack of slip rings is a suitable alternative for induction generators to be used in these systems. However, these generators use full power converters which means higher power losses. In this paper, an ultra-efficient three-level converter, called T-type converter, is used in a back-to-back configuration as power electronic interface for PMSG-based small-scale WECS. Then, simulations are carried out to evaluate the efficiency of the system and compare it to conventional two- and three-level back-to-back configurations. Meanwhile, thermal analysis is carried out to investigate the thermal loading of different switching components of the converter. Data given by this analysis can be further used to evaluate system reliability. Therefore, system reliability is calculated and compared to conventional two- and three-level converter systems.

The current-controlled grid-connected inverter with LCL filter is widely utilized in the distributed power generation systems at remote places with weak grids. Oscillations in weak grids have raised the stability issue in grid-tied inverter systems, and the quality of the injected power into the grid is highly affected by the variations of grid-side inductance. In this study, a multi-loop control has been applied in the LCL-type grid-connected inverter based on capacitor current feedback control method. Computational delays in the control unit can remarkably influence the damping capability of this method. The accuracy of the modeling has been increased by considering the computational delays of the capacitor current active damping inner loop as well as the grid current outer loop. The impact of the computational delay is eliminated by the proposed approach, and the performance of the control system has been remarkably enhanced. The harmonic attenuation of the grid voltage has been improved by utilizing virtual series and parallel impedances, which leads to strong stability-robustness and high harmonic-rejection-ability even in severe variations of the grid-side inductance. Simulation results verify the credibility of the proposed approach, and the quality of the injected power is proved to be improved in a weak and harmonically distorted grid.

Multilevel inverters are a new generation of DC–AC converters at medium and high voltage and power levels. In this paper, a new single-phase cascaded multilevel inverter is presented. For this purpose, a new basic cell is presented at first. Then, the new multilevel inverter structure is yielded by series connection of these cells. The proposed new cell is only capable of generating positive voltage levels, and therefore, to produce zero and negative voltage levels, the proposed structure is constructed based on H-bridge module. In order to reduce the maximum blocking voltage especially on H-bridge switches, the cascaded connection of the proposed converter is investigated. A comprehensive comparison is carried out between the proposed multilevel inverter with the classical and recently introduced structures in terms of the number of switching devices, the number of drivers, the total blocking voltage of the switches as well as the loss and efficiency. The accuracy of the proposed inverter’s performance is simulated in MATLAB/Simulink in symmetric and asymmetric topologies for a 17-level and 23-level output voltage respectively, and then evaluated by the laboratory prototype.

In this paper, a current sharing method based on the circular chain control (3C) method is proposed for controlling parallel inverters of unequal ratings in uninterruptible power supply (UPS) applications. Due to its circular structure, 3C is one of the most convenient methods which can be used in UPS as well as microgrid systems. However, the conventional 3C control strategy is only applicable to inverters of equal power ratings. The proposed method not only retains the circular structure of the 3C method, but also provides adaptability for the parallel operation of inverters with different power ratings. Moreover, this method adds hot-swap capability to the parallel inverter. A two-loop control structure is used to control the inverters. For proper current sharing, currents of inverters are conveyed in a circular structure with appropriate gains through control links. Simulation and experimental results for linear and nonlinear loads verify the effectiveness of the proposed strategy.

In the grid-tied PV inverter systems, the design of a proper power conditioning system is an important issue to ensure high-quality power injection to the grid. Among various control methods for grid-interfacing inverter with LCL filter, converter-side current feedback (CCF) method has been widely used due to its inherent resonance damping feature. Applying the CCF method requires extra attention to the delay effect of the control system. In such systems, the delay narrows stability region of resonance frequency of the CCF control method, especially, in the presence of wide variations of the grid inductance. Adequate tuning of the LCL filter and consequently the proper choice of the resonance frequency can remarkably affect the performance of the CCF control. In this paper, a tuning procedure for LCL filter has been proposed. Mathematical tuning of the Proportional Resonant (PR) controller parameters has also been included to avoid typical trial and error procedures of tuning. Simulation of the overall system also includes solar panels, maximum power point tracking algorithm, Modified-Y-Source inverter, and LCL filter to model the grid-tied PV system with the most possible details. Simulations are carried out in MATLAB/Simulink and it has been proved that the proposed control system maintains its stability against grid parameters variations.

In this paper, a bidirectional diode containing multilevel inverter is introduced to reduce the number of switching elements especially in the case of a high number of output voltage levels. In comparison with classic and recently introduced symmetrical topologies, which are trying to reduce the switch count, this topology has a lower number of semiconductor switches in the same number of output voltage levels. This makes the proposed inverter to be a suitable choice for medium voltage applications like renewable energy applications as well as medium voltage electric drives. Moreover, it can be used in a cascaded configuration for high voltage levels. To depict the performance of the proposed structure, a comprehensive comparison is made between this topology and classic and recently proposed symmetric topologies in terms of switch and gate driver count, power losses, and cost. The performance of the proposed symmetrical 11‐level converter is analyzed and simulated in MATLAB/Simulink for both PWM and selective harmonic elimination switching methods. Not only the results are desirable but also the experimental results of laboratory prototype validate the simulation results.

Inverters as one of the most important elements of power systems have been profoundly developed in recent decades and their performance has attracted researches in control and structure point of view. In this study, a novel structure based on the switch-diode-source cell is proposed for a multilevel converter that is capable of bidirectional feeding. The proposed structure is presented for symmetrical mode and the number of power electronic devices is decreased in comparison with similar works. Considering recent proposed symmetrical structures, the proposed structure has the superior condition in terms of semiconductor switches and drivers count as well as switching loss. Also, total blocked voltage (TBV) of the proposed converter is compared with conventional and novel symmetrical converters. Then, switch costs of the proposed converter are compared with the structure that its TBV is the lowest. The performance of the proposed symmetrical seven-level converter is analysed and simulated in MATLAB/Simulink for both PWM and selective harmonic elimination switching methods. Not only the results are desirable, but also the experimental results of laboratory prototype validate the simulation results.

Proton Exchange Membrane Fuel Cell (PEMFC) systems are environment-friendly systems that can be used as distributed power generation (DPG) system. As DPG units are usually utilized in weak power distribution systems, the grid inductance variations should be investigated during the control design stage of the grid-tied fuel cell systems. In recent years, LCL filter is broadly utilized to grid connection of DPG units, and the proper design of this filter is an important issue. In this paper, converter side current feedback (CSCF) method has been applied due to its innate damping feature to integrate PEMFC fuel cell system through LCL filter into weak power distribution system. The impact of delay should be considered as it limits the stability region of the resonance frequency of the CSCF control method especially, in the presence of wide variations of the grid inductance. Precise-tuned LCL filter design and consequently, the proper choice of the resonance frequency can remarkably affect the performance of the CSCF control. An adequate-tuned design procedure for LCL filter parameters has been proposed in this paper. Step-by-step tuning of the PR controller parameters has also been included to enhance the power quality. The grid-tied fuel cell system with modified-Y-Source inverter and LCL filter as an interface between inverter and grid has been simulated to analyze the quality of the injected power. Simulation results in MATLAB/Simulink environment verify the suitable performance of the proposed power conditioning system as well as its stable operation versus wide variation of weak grid inductance.

Speed control of conventional low-voltage low-power induction motors (LV-LP-IMs) by two-level voltage source inverter (2LVSI) has some difficulties due to limitations of LV-LP-IMs especially insulation system. Besides, the use of multilevel inverters is not cost-effective either. In this paper, the new topology of reduced-switch-count three-level inverter with only eight switches is proposed for speed controlling of LV-LP IM. Eight-switch inverter is a newly three-level converter, which has the fewer number of switching devices, lower cost, smaller volume compared with the conventional three-level inverters, while it has sufficient switching vectors to speed control of IMs. In this paper, the structure and switching vectors of the eight-switch inverter are analyzed, and the direct torque control method based on the switching table and voltage balancing of the DC input voltage are presented for the LV-LP-IM speed control. Simulation results, considering different work conditions, are presented in order to validate finally the good performance of the proposed method. Moreover, the obtained results are compared with 2LVSI and conventional three-level inverters in different aspects.

Distributed power generation systems use power electronics converters as interface for connection to grid. The connection through an LCL filter offers certain advantages, but it brings also the disadvantage of having a resonance frequency. Power electronic converter control is challenging due to filter resonance peak. In this paper a three level ultra-efficient converter called T-Type converter is connected to grid through an LCL filter and its injected current is controlled by PR controller. The resonance peak of the filter is also damped using filter capacitor current feedback. A step by step mathematical design procedure for controller and filter capacitor current feedback coefficient is investigated in details. Simulations are carried out in MATLAB/Simulink environment and results depict suitable performance of the system with designed parameters.

Hybrid modular multi-level converters (Hybrid-MMCs) which are modular multi-level converters including full and half bridge sub-modules, are recently used in high-voltage direct current (HVDC) transmission systems. Compared to its non-hybrid counterpart, these converters have several advantages such as the ability to nullify the DC side fault current and controlling AC side reactive power during the faults. This paper proposes a novel modified phase shifted PWM method (PS-PWM) which uses a combination of an improved PS-PWM with cancelled mismatch pulses and a third harmonic injection method. The proposed method not only reduces output voltage harmonic content and uneven loss distribution between sub-modules but also extends the linear operating range of the inverter, which improves the DC bus utilization. The mathematical analysis is derived for the proposed method and in order to study the efficiency of the system using proposed method, the loss calculation has been done and compared with traditional PS-PWM method. Simulation results in Matlab/Simulink depict the suitable performance of the presented scheme.

Distribution networks are often very wide and are comprised of vast number of feeders. Always feeders are considerably broadened, and for them lots of maneuver points placements are predicted for load relocation and reducing the power outage period of customers. In this paper, locating the switching equipment in a radial distribution feeder is investigated. Given to budget restrictions and looking for technical and economic considerations and importance of load points, a combinatorial objective function is defined that pursues three main goals. First goal is minimizing installation and maintenance costs and power outages by optimal switches placement so that maximum budget is considered. For the second goal, consuming available and financial resources in distribution network is investigated in order to optimizing reliability. As the third goal, reaching a particular reliability level with the lowest price is considered. For optimization problem single objective and double objective genetic algorithm are employed. Experiments on a paradigm network and on a real Iranian power distribution network has validate the efficiency of the proposed method.

In this paper, a control algorithm based on Recursive Discrete Fourier Transform (RDFT) is proposed for 3-phase, 4-leg shunt active power filter (APF) to prevent harmonic currents, compensate reactive power and neutral line current and balance the load currents under unbalanced non-linear load and nonideal mains voltage conditions. The APF is composed of a 4-leg voltage source inverter (VSI) with a common DC-link capacitor and hysteresis band PWM current controller. The control algorithm takes advantage of a computationally efficient RDFT and it is based on extraction of the positive sequence component from the measured current with the Fortescue decomposition. The extraction of the positive sequence component guarantees the accurate computation of current components under both balanced and unbalanced line current conditions. The advantage of the proposed method to the common control techniques of the active filters falls in the fact that the proposed method extracts the harmonic and the fundamental components faster and with more accuracy and has a faster dynamic response. Simulation results indicates that the 4-leg APF with RDFT control algorithm, compensates harmonics and neutral currents and balances load currents under all non-ideal mains voltage conditions adequately.

Among electric energy storage technologies, we select NaS battery (Natrium Sulfur battery) systems for coupling with power plant because of their enough technological maturation and less environmental impacts. The goal is investigating the coupling efficiency on profit increment considering various intensities of power plant's fuel constraint. In order to reach this goal, the amount of overall profits of fuel-constrained power plant, NaS battery plant and their coupling are first calculated in a specific time interval. Then, the coupling efficiency is determined using incremental profit rate. Having an appropriate strategy to calculate this parameter is essential. Hence, a comprehensive approach to self-schedule of individual and coupled plants is developed. This comprehensive self-scheduling approach is therefore formulated and solved as a mixed integer non-linear programming (MINLP) problem. Numerical results for a case study are discussed.
