dc.subject.otherIn order to fulfill the power quality requirements of the electrical power system, the static synchronous compensators (STATCOMs) emerges as an attractive solution. Among the STATCOM topologies, the cascaded topologies have become interesting options for medium- and high-voltage applications. Indeed, their capacity to use mature semiconductor technology, high efficiency, and low filtering requirements have aroused the interest of companies in the STATCOM sector. Among the cascaded topologies, the modular multilevel converter (MMC) presents superior performance under unbalanced voltage conditions and negative sequence injection in STATCOM application. Therefore, the MMC-STATCOM is considered in this work.

local.description.resumoThe application of modular multilevel converters (MMC) in medium voltage static synchronous compensators (STATCOMs) has been investigated in recent years. A huge challenge for MMC-STATCOM is to compute the gain of the controllers. Therefore, the contribution of this paper is the proposal of a control tuning methodology for MMC-STATCOM. For this purpose, the control and tuning strategies are presented. Since MMC-STATCOM can employ different modulation strategies, two distinct modulation strategies are considered: nearest-level control, with variable switching frequency; and phase-shifted carrier pulse-width modulation, with fixed switching frequency. Moreover, the proposal was validated through simulation and an experimental platform. The results indicate that the power response follows the reference, besides supplying the internal losses of the converter. The 10% ripple tolerance of the submodule voltages is respected in steady state for both modulation strategies. Moreover, the 5% total demand distortion (TDD) limit recommended by the Institute of Electrical and Electronics Engineers (IEEE) standard is attended. These results demonstrate the effectiveness of the controls employed.
