Hybrid Compensation System Using PVDSTATCOM and SVC for Enhanced Power Quality in Low Voltage AC Distribution Grid

As electricity demand continues to rise, ensuring a stable and high-quality power supply becomes increasingly important. One major challenge that power systems face is maintaining power quality, which can be affected by issues such as voltage sags, swells, low power factor, and harmonic distortions. Integration of distributed energy resources like photovoltaic (PV) systems also presents challenges in maintaining the power quality of the grid. Effective mitigation of these issues is essential. DSTATCOMs are known for their ability to compensate reactive power and filter harmonics, but they are often associated with higher complexity and cost. On the other hand, SVCs offer rapid adjustment of reactive power, enhancing voltage stability and power quality with relatively simpler implementations. The integration of SVC and DSTATCOM technologies aims to combine their benefits and address their limitations. This involves using the dynamic response capabilities of SVC to provide reactive power and utilizing a PV-DSTATCOM to provide active power and harmonic compensation. The integration aims to reduce the overall complexity and cost of power quality management systems while ensuring a robust and stable electrical grid.
