Hi friend!
I'm Hiangcuong and I just finished my PhD thesis about APF(Active Harmonic Filter). I have do the simulation and experience model for the APF 3 phase 4 wires, 50A using dq algorithm. I also worked with fuzzy and GA algorithm. For your project, it's easily when I just need to change the current reference detection block following GA or fuzzy algorithm.
Hope I can help you.
