This paper deals with a hybrid small hydro-photovoltaic (PV) array with a battery storage based microgrid for rural areas. This microgrid is presented for an uninterrupted electrification and provides power to the local loads in remote areas. For small hydro, a self-excited induction generator (SEIG) is utilized with excitation capacitors. The Volterra filtered-X least mean square (VFXLMS) technique based on a multichannel structure is utilized to address power quality issues because of nonlinear loads tied to the microgrid. The presented filter effectively suppresses dominant harmonic components of load currents and estimates fundamental frequency signal of load currents. The accuracy of presented technique is enhanced by mitigating effect of DC-offset in sensed signals from generator currents. The PV array through a boost converter and battery through a bidirectional converter are tied at DC link of voltage source converter (VSC). The bidirectional converter manages export/import power from/to the battery. The response of hybrid microgrid is presented at balanced/unbalanced load and PV insolation changes.
