Moving Average Filter Based Dstatcom Control Approach
(2025) Özer Ali Sait; Karaca Hulusi
Self-excited induction generators (SEIGs) are commonly preferred in standalone renewable energy systems due to their low cost and robust construction. However, the voltage and frequency stability at the SEIG output may be adversely affected by varying reactive and active power demands depending on the load profile. In such systems, DSTATCOM is used to provide voltage and frequency regulation, and its performance largely depends on the applied control algorithm. In this study, a moving average filter (MAF) based dq control algorithm is proposed for DSTATCOM supported SEIG systems. The MAF structure contributes to more accurate calculation of reference source currents by reducing the effect of harmonic content. The proposed control method is tested under nonlinear load and unbalanced-nonlinear load conditions. The results show that the system maintains voltage and frequency stability and successfully suppresses disturbances.
