“…Because of several advantages of MMC compared with conventional inverters , work was performed on the different topologies, harmonic control, and dynamics of MMCs over the last few years , but much still remains to be understood and tested in terms of dynamic performance, controller performance, stability analysis, harmonic mitigation schemes, and circulating current mitigation schemes especially for converters configured with a large number of modules, before this type of converter can be fully deployed in real time applications . The basic operations of MMC have been reported, but detailed expressions for the arm currents in terms of state space approach have not been presented so far.…”

“…Explicit expressions are very helpful to forecast the harmonic components and the phase angles of multiple frequency components present in legs of MMC. However, the multiple frequency components can vary by varying the control signals, and different control schemes have been suggested in literature . Because of the uneven voltage distribution in the arms of a phase, circulating currents start to flow through the legs of the converter.…”

Summary Grid‐connected photo voltaic (PV) systems are being developed very fast and systems from a few kW to tenths of a MW are now in operation. As an important source of distributed generation (DS) the PV systems need to comply with a series of standard requirements in order to ensure the safety and the seamless transfer of the electrical energy to the grid. Multilevel voltage source converters (VSC) is a heart of the PV system and are emerging as an important power converter options for low, medium, and high‐power applications. These VSCs have bought numerous advantages, especially in renewable energy systems such as PV and wind energy systems. In this article, several topologies of VSCs, which brings together some concepts from traditional converters and multi‐level converters, are presented. Also, several control strategies for controlling current, voltage, active power and reactive power have also been reviewed. Various topologies with their technical aspects have been reviewed and the best suitable topology and control scheme for grid connected PV and wind energy systems has been suggested.

“…Such solutions are often called Custom Power Devices (CPD). There are two main methods for compensation of voltage-disturbances in power systems using power electronics devices: current oriented parallel devices (STATCOM-static synchronous compensator, SVC-static VAR compensator); and voltage oriented series devices (DVR-Dynamic Voltage Restorer) [9,10]. In this article only series compensation systems will be considered.…”

This article presents a study of an AC voltage stabilizer based on a three-phase hybrid transformer combined with a matrix converter. The proposed solution is used to control AC voltage amplitude and phase shift. By adjustment of these voltage parameters we can reduce the effects of overvoltage, voltage dips or lamp flicker. Such negative phenomena are very significant, particularly from the perspective of the final consumer and sensitive loads connected to the power network. Often the voltage in the power system can be adjusted using a mechanical or thyristor controlled regulator, which in a stepwise manner switches the taps of the electromagnetic transformer. The method for obtaining continuous control of the voltage magnitude and phase shift with the use of a conventional transformer with two output windings and a matrix converter is presented in this paper. The operating principles, mathematical model and properties of the proposed voltage stabilizers are discussed in this paper. The main part of the article will be devoted to the mathematical model which is based on an averaged equation. Computer simulation results are presented and compared with the results of a mathematical study.
