Power quality improvement using Cuckoo search based multilevel facts controller

Abstract EN

Nowadays, the improvement of power quality is the major concern in power system scenario.

As per literature analysis so far a huge number of technique implemented to improve power quality of the system.

Out of these, the FACTS controllers plays a key role.

This paper is presents a concept of series and shunt active filters implemented with 9-level inverters to reduce the harmonic distortions.

The series active filter control structure is implemented with system and load voltages, the reference currents required for shunt active filter is implemented using PQ-control theory.

To get better improvement of power quality and harmonic distortion, the series and shunt controllers are implemented with CUCKOO controller.

This proposed system is tested and verified in MATLAB/SIMULINK.
