A comparative study on the performance of custom power devices for power quality improvement

This paper presents a review on the performance of four series and parallel custom power devices (CPDs) including active voltage conditioner (AVC), active power conditioner (APC), dynamic voltage restorer (DVR), and distribution static synchronous compensator (D-STATCOM). The CPDs are simulated on the modified IEEE 16-bus radial distribution system using Matlab/Simulink software to investigate performance efficacy of each devices under various power quality (PQ) disturbances including voltage sags, voltage interruption, and harmonic distortions. The simulation results demonstrate that the effectiveness of each device to compensate different types of power quality disturbances toughly depends on the device's arrangement and characteristics during PQ disturbances.
