Elimination of harmonics using bacterial foraging optimized shunt active power filter

Abstract

The shunt active power filter is gaining more attention within the field of harmonics minimization because of its effective performance in this area, where a load which is nonlinear, connected and generating the harmonics problems in the system. Here in the paper a shunt active filter with PI controller is used to eliminate harmonics also a new algorithm which is BFO (Bacterial Foraging Optimization) algorithm is used to optimize the parameter of PI controller through self tuning and provides a parameter values. The BFO algorithm is a new bionic optimization algorithm to follow the E.coli bacteria in multioptimal optimization function. The proposed model is simulate in MATLAB/SIMULINK.
