Harmonic Voltage Control in Distributed Generation Systems Using Optimal Switching Vector Strategy

Electrical and Electronics Engineering

The increasing integration of distributed generation (DG) systems in modern power grids has highlighted the importance of maintaining power quality and ensuring efficient voltage control. Harmonic voltage distortion, caused by non-linear loads and inverter-based DG sources, is a key challenge. This paper presents an innovative approach for harmonic voltage control in DG systems using an Optimal Switching Vector Strategy (OSVS). The proposed strategy leverages advanced control algorithms to optimize the switching of power electronic devices, such as inverters, to reduce harmonic distortion and maintain a stable voltage profile. By minimizing harmonic components in the system, the OSVS enhances power quality, improves voltage regulation, and ensures efficient operation of DG systems. The effectiveness of the approach is demonstrated through simulation studies, showing significant reductions in harmonic voltage and improved performance under varying load conditions. The results confirm that the OSVS is a promising solution for harmonic voltage control, ensuring reliable and stable operation of DG systems in modern power networks.
