This paper presents a new way of organizing a wind farm with a large number of small to medium-sized turbines. Each wind generator has been included in a switching module of a modular multilevel converter (MMC), which generates the output voltage by near level control (NLC). The proposed topology reduces the number of semiconductors required, switching losses, and voltage filtering requirements. This topology replaces the usual configuration where each wind turbine is connected to a three-phase two-level back-to-back converter plus a filter and then connected in parallel with the other wind generators. To test the topology and its control performance, a case has been developed and simulated for generator configurations producing the same power, for generation imbalances between phases and for imbalances between arms. The analysis of the data shows that the converter works correctly and that it can deliver power to the grid in a balanced way even if the generation has imbalances. The generation imbalances between phases are compensated through the average value of the circulating current, while the imbalances between arms are compensated through the 50 Hz circulating current.

This article focuses on smoothing the large power peaks that wave energy converters (WECs) inject into the electrical grid. The study is carried out for a single WEC where the generated power is delivered to the grid by means of a power converter. Two different measures have been considered to improve the power quality of the grid connection. Firstly, the electronic converter has been chosen a modular multilevel converter (MMC) to allow replacing the standard high voltage capacitors of the DC link by low voltage ultracapacitors distributed across the modules of the MMC. Secondly, the MMC is controlled using a non-linear vector current control. The results show that the power delivered to the grid becomes approximately constant when using ultracapacitors. Furthermore, the non-linear vector current source provides the grid connection converter with the necessary fast dynamic response to avoid large variations in the DC voltage. Keywords: modular multilevel converter (MMC); non-linear vector current source; ultracapacitor; wave energy converter (WEC).

A new topology has been recently proposed for grid-connected photovoltaic (PV) systems, using modular multilevel converters (MMCs) and distributing PV panels throughout the MMC cells. This topology has two main advantages: it reduces the power losses related to moving the energy into the MMC capacitors from an external source, and it removes the losses and costs related to the DC to DC converters used to track the maximum power point on string converters or central converters, because that task is delegated to MMC cells. However, traditional pulse width modulation (PWM) techniques have many problems when dealing with this application: the distortion at the output increases to unacceptable values when MMC cells target different voltages. This paper proposes a new modulation technique for MMCs with different cell voltages, taking into account the measured cell voltages to generate switching sequences with more accurate timing. It also adapts the modulator sampling period to improve the transitions from level to level, an important issue to reduce the internal circulating currents. The proposed modulation has been validated using simulations that show a consistent behavior in the output distortion throughout a wide operation range, and it also reduces the circulating currents and cuts the conduction losses by half. The behavior of this new topology and this new modulation has been compared to the mainstream topology with external PV panels and also to a fixed carrier modulation.

Modular multilevel converter (MMC) is a type of electronic converter currently used as voltage source in real HVDC transmission systems. This paper presents, as an alternative, a control system designed to operate an MMC as a nonlinear vector current source (NLVCS). From the design point of view, it features advantages such as constant switching frequency, robustness against grid parameters changes and that the algorithm is entirely designed from space vectors. From the application point of view, the main advantages are its fast dynamic response combined with its capability to handle large amounts of electric power. Together, these two features allow the MMC to deal with highly variable renewable energies. To show the advantages of the proposed control system, it has been chosen a very demanding application: wave energy. In this type of applications, the random nature of the sea produces large and fast variations of the generated power, that enters the DC link and that the grid side converter has to handle very fast, injecting it into the grid in order to maintain the DC voltage constant. The capability of the NLVCS for MMC to handle the energy generated has been tested in two different wave energy applications. Firstly, on a single wave energy converter (WEC), a point absorber. This case is characterized by smaller and faster power changes. Secondly, on a wave farm made up of 200 WECs connected to the grid through an MMC. This case is characterized by much larger but smoother power changes. Wave farms, WECs and MMC are large and sophisticated facilities or devices that are almost impossible to gather in the same laboratory. Consequently, the features of the new control system for MMC and the advantages that provide in the connection of wave energy power plants and point absorbers to the grid has been simulated using detailed models. The results demonstrated the capability of the MMC operating as NLVCS to deal with the fast and random power changes present in renewable energy sources.

This paper is focused on the modular multilevel converter (MMC) topology that uses the near level control (NLC) method. Specifically, it addresses the relationship between the number of levels or switching modules, the switching frequency and the harmonics superimposed on the generated voltages and currents, making a comparison with the high and medium voltage AC codes. Furthermore, it also assesses the possibility of connecting the MMC to the electrical grid without using any coupling inductor, either using a transformer or simply directly. Finally, it shows how to automate the simulations necessary to select the number of levels and the switching frequency.

This paper is about the control of Modular multilevel converters, an innovative technology in the design of converters, which is beginning to be included in real installations. Papers about this topic include simulation models, circulating current reduction, voltage modulators, capacitor voltage balancing and control issues. The scheme for current source regulation used in this article includes all control loops, which are, from the outermost to innermost, DC bus voltage regulator, current regulator, voltage modulator, capacitor voltage balancing, and a PLL for the synchronization to the grid. Disposition-sinusoidal pulse width modulation is used as the voltage modulator, and an enhanced control strategy in the stationary reference frame for 3-phase MMCs is used for the inner current control loops. Very detailed simulations of the complete control system have been performed for both the enhanced control strategy in the stationary reference frame, and the well-known control in the synchronous reference frame, as well as some experiments using the hardware-in-the-loop simulation technique. The validation of these control strategies is made by a comparison of the capability of each one to compensate the harmonic distortions of the utility grid according to the grid code. The correct operation has been tested in the case of a strong/weak grid, unbalances and grid failures.

This review article is mainly oriented to the control and applications of modular multilevel converters (MMC). The main topologies of the switching modules are presented, for normal operation and for the elimination of DC faults. Methods to keep the capacitor voltage balanced are included. The voltage and current modulators, that are the most internal loops of control, are detailed. Voltage control and current control schemes are included which regulate DC link voltage and reactive power. The cases of unbalanced and distorted networks are analyzed, and schemes are proposed so that MMC contribute to improve the quality of the grid in these situations. The main applications in high voltage direct current (HVDC) transmission along with other medium voltage (MV) and low voltage (LV) applications are included. Finally, the application to offshore wind farms is specifically analyzed.

This paper examines the question of how to use project-based learning to increase student performance and satisfaction in a power electronics course addressing the topics of dc/dc and dc/ac converters, the assembly of a dc/dc converter, and the use of a commercial speed drive. A detailed presentation of the methodology is shown, and the results are analyzed by comparison to previous academic years and by satisfaction surveys. The new course design applies the jigsaw cooperative learning strategy to have students learn the theory of converters, solve problems, and perform simulations, before carrying out projects that solve real-world problems, such as the power converter for a competition solar vehicle (2014/15 course) and power converters for an air conditioner with inverter technology (2015/16 course). Rubrics were used to evaluate the students' work reports and the simulations. The project deliverables are presented and assessed in two design reviews, the first version covering the design and an open loop simulation, and the second covering the closed loop simulation and verification of specifications.

This chapter reviews the control systems used to enable STATCOMs to carry out their most important task, which is to deliver reactive power to the electrical grid. Later on, other control systems designed for more advanced applications are discussed, such as compensating the nonlinear loads. Later, the design of the control system when STATCOMs are connected to unbalanced electrical networks is presented. Several strategies are presented for controlling the converter, either as a linear current source which is also known as controlled Voltage Source Converter (VSC) based on the use of Proportional-Integral (PI) controllers, or as nonlinear current source, based on the use of hysteresis bands. Other systems, such as the firing algorithm of the switches or system synchronization with the grid, are also discussed.

Se presenta un nuevo emulador para turbinas eólicas de paso fijo, que permite realizar pruebas de laboratorio de los sistemas de control de los generadores asociados a las turbinas eólicas. La novedad del emulador consiste en utilizar un esquema en lazo abierto. El emulador consiste en el acoplamiento en serie de los siguientes elementos: una fuente de tensión de CC, una resistencia de potencia y un motor de CC. La modificación de la tensión en CC tiene el mismo efecto que la variación de la velocidad del viento en una turbina eólica. Se incluyen: 1) los fundamentos teóricos del emulador, 2) la realización de simulaciones utilizando las aplicaciones informáticas Excel y Matlab/Simulink, y 3) los resultados experimentales obtenidos en una bancada de máquinas eléctricas. Se comprueba que el emulador permite reproducir las curvas de potencia mecánica de una turbina de paso fijo, aunque con ciertas limitaciones a baja velocidad de giro.

A simple algorithm has been developed to control small and large multilevel inverters using Space Vector Modulation. It looks for a suitable hexagon near the reference voltage rather than the usual three nearest vectors. Then, switching vectors and their duty cycles are computed using straightforward equations, independent of the number of levels and easy to use in digital microprocessors. Several simulations have validated this method, finding that these duty cycles are exactly the same than others, computed using more complex methods.

Project-based learning (PBL) and cooperative learning are, in various aspects, very superior education methodologies compared to other traditional ones. They are highly appropriate methodologies for elective courses, as they exert a strong attraction on the students, quite apart from their educational advantages. This paper describes how PBL and cooperative learning have been used to teach the topics of power supplies and photovoltaic electricity within two elective undergraduate courses. A project is carried out for each of the two topics. Moodle is used as the e-learning platform to provide the course materials and the wiki resource and to allow the submission of assignments. The simulation is done by means of Simulink. Work has been done to develop skills for project planning, group management of the work, technical document writing and presentations in public. The methodology has been seen to be successful, as all the students who have followed it over the last few years have passed the courses in which it was included, Design of Industrial Applications and Industrial Electronics. Examples of the rubrics for assessing the projects and examples of the projects themselves are also included.

This article presents a methodology to encapsulate, not only the functionality of several SoC modules, but also the connections between those modules. To achieve these results, the possibilities of Algorithmic State Machines (ASM charts) have been extended to develop a compiler. Using this approach, a SoC design becomes a set of chart boxes and links: several boxes describe parameterized modules in a hierarchical fashion, other boxes encapsulate their connections, and all boxes are linked together using simple lines. At last, a compiler processes all required files and generates the corresponding VHDL or Verilog code, valid for simulation and synthesis. A small SoC design with two DSP processors is shown as an example.

Algorithmic State Machines are a 40-year old tool for the design of digital circuits. They are a good alternative to Finite State Machines, where only states can be properly described, but all operations must be annotated as lateral comments. This paper shows the inner relationship between ASM diagrams and modern languages used to describe hardware and it proposes several modifications to the standard methodology to allow automated tools to produce Verilog or VHDL code from these diagrams. The new notation is more complete and consistent and thus more convenient for CAD tools.

The devices of power used in matrix converters (M.C.) need some operation sequences to commute the current in a safe way. These operation sequences are what we denominate strategies of current commutation, being these more complex than in other converters. In this article a comparative analysis of the different strategies of current commutation will be carried out by means of simulation and they will be implemented in a experimental matrix converter to analyze its behaviour. As comparison criterion of the different strategies that have been used, the total harmonic distortion (THD), the efficiency of the converter, the maximum commutation frequency and the necessary hardware requirements for the implementation of the strategies.
