Design And Performance Evaluation Of Active Power Filter For Micro Grid Connected Distribution System

Abstract

In this work, a new control mechanism for three-phase power converters operating in parallel that allows for the equitable distribution of linear and nonlinear loads without the need for inter converter communication is described. Harmonics can be mitigated with the help of many controllers, which is why active power filters exist. The level of harmonics is evaluated by measuring the overall harmonic distortion at the point of origin. When applied to nonlinear loads, the Active Power Filter (APF) concept uses power electronic switching to generate harmonic components that cancel out the nonlinear loads' equivalent harmonic currents. Harmonic currents are blocked from entering the supply by devices like these, which convert DC to AC currents that are out of phase with the load and inject them into the AC line. A comparative analysis has been done by comparing the Simulation results of PI controller method and ANN method. Based on the analysis, the better harmonic reduction controller technique is suggested. Simulations and comparisons of the PI method and ANN method are performed in MATLAB Simulink.
