Development of Single-Phase Shunt Active Power Filter for Reduction of Current Harmonics in Data Center Power System

In modern power systems, the integration of renewable energy sources and the increasing use of power electronic devices can lead to harmonic distortions, imbalances and other power quality issues. These issues can lead to equipment failures, overheating and increased energy losses. Active filters can mitigate these issues by injecting a compensating current into the power system to compensate for harmonics and improve the power factor. Shunt Active Power Filters (SAPF) play an important role in the smart grid by helping to improve power quality. The aim of this paper is to present a simple model of a SAPF that has one current control loop with an LCL filter output current as a feedback signal and a PI controller. The development of the prototype model and its design with all the necessary parameters to build a simulation model are presented in detail. The simulation model is also verified experimentally and a comparison between the simulation and experimental results is presented.
