Multi Microgrid Current Quality Conditioning using Active Custom Power Conditioner

Multi Microgrid (MMG) generally constitutes two or more microgrids (MGs), connected together. The MGs in turn incudes renewable energy resources. The variable and nonlinear loads connected to the MMG, when connected MMG has been subjected to many power quality issues that are based on current such as unbalance, neutral currents and harmonics. An Active Custom Power Conditioner (ACPC) provides a solution to all these concerned problems. The ACPC in addition to neutral and unbalance compensation provides harmonic mitigation. This is achieved by adapting active power filtering with proposed control technique. A novel control technique based on 1-phase PQ theory is proposed to improve its performance in providing harmonic compensation and compared with conventional control techniques like UVTG, 3-phase PQ theory with varying load conditions in the MMG.
