“…Among the FACT controllers, STATic synchronous COMpensator (STATCOM) is a shunt‐type device which improves power transmission capability, the power factor and the voltage profile of electric lines by injecting or absorbing adequate amount of reactive power [2, 3]. Moreover, a STATCOM with high dynamic response can improve the system stability under fault conditions [4], can mitigate the voltage fluctuations in wind generation systems [5, 6] and can alleviate the flicker problems caused by arc furnaces in the point of common coupling (PCC) [7, 8].…”

In this study, a transformer-less STATic synchronous COMpensator (STATCOM) based on cascaded H-bridge (CHB) multilevel converter with floating DC links is presented. This study introduces a control strategy based on state feedback control algorithm in order to supply reactive power to the grid and to compensate the total losses in the internal H-bridge cells. Using this strategy, the converter stability and the fast dynamic response are guaranteed. Moreover, a voltage balancing strategy is proposed, which not only regulates the DC-link voltage of H-bridge cells to the reference value, but also evenly distributes total reactive power among the converter cells, even when there is difference between the losses of H-bridge cells. A 21-level CHB-based STATCOM is simulated in PSCAD/EMTDC environment to evaluate the performance and effectiveness of the new control strategy. Furthermore, the validity of new method is verified on a down-scaled 7-level CHB prototype.
