Summary A controller based on the model is presented for a single‐phase grid‐tied inverter of 2N + 1 levels, which is based on the modular multilevel converter (MMC) topology, where N is the number of cells per arm. This is referred to as an MMC‐based inverter in this paper. The controller has the purpose to assure a good performance of the converter operation both internally and during grid connection. For this, the proposed controller involves four control loops, namely, overall energy regulation, energy balance between arms, circulating current, and injected current loops. Notice that the proposed controller by itself guarantees voltage regulation at the arms level only. To guarantee individual regulation of each cell capacitor voltage, the proposed controller is then combined with the phase‐shifted carrier‐based pulse‐width modulation (PSC‐PWM) scheme. Experimental evidence is exposed to assess the performance of the proposed control scheme. The experimental setup considers a grid‐tied inverter based on an MMC of seven levels (N = 3). The proposed controller and the experimental prototype are implemented in a hardware‐in‐the‐loop platform. The experimental tests include responses to step changes in the load power and unbalance in the initial capacitor voltages.

Summary The modular multilevel converters (MMCs) are frequently preferred for medium and high power energy conversion systems thanks to their modular structure and high quality output waveform. The remarkable studies related to the MMC have been carried out in recent years, which are mainly focused on its topology, control, or application. In this paper, MMC circuit topologies consisting of traditional submodule cells and new proposed configurations are introduced, and their control process, modulation techniques, and application areas are discussed in order to provide the readers the current state of the art of MMC technology. A wide part of this article is devoted to demonstrate the recent contributions arising in MMC studies. In this context, this paper not only outlines the circuit topology, control objectives, and applications of the MMC but also presents a comprehensive review, principally in terms of the latest developments of it. Ultimately, detailed proposals and new possible topics are provided to drive future expectations of MMC technology.

“…These current and voltage controllers are implemented into the synchronous reference frame [21]- [23], their control references are continuous, decreasing the steady-state errors when traditional proportional-integral controllers are employed. A nonlinear discrete-time model along with an optimal stabilizing controller was implemented in [8] withrelatively small stored energy levels, which adversely affect their stability, as opposed to larger grids. The discrete-time Hamilton-Jacobi-Isaacs optimal control method is employed to design an optimal grid stabilizer.…”

This article presents a novel application of four leg inverter with conventional Sinusoidal Pulse Width Modulation (SPWM) Scheme to Unified Power Quality Conditioner (UPQC). The Power Quality problem became burning issues since the starting of high voltage AC transmission system. Hence, in this article it has been discussed to mitigate the PQ issues in high voltage AC systems through a three phase Unified Power Quality Conditioner (UPQC) under various conditions, such as harmonic mitigation scheme, non linear loads, sag and swell conditions as well. Also, it proposes to control harmoincs with various artificial intelligent techniques. Thus application of these control technique such as Artifical Neural Networks, Fuzzy Logic makes the system performance in par with the standards and also compared with existing system. The simulation results based on MATLAB/SIMULINK<sup>TM </sup>are discussed in detail to support the concept developed in the paper.
