This paper deals with control of hybrid standalone power generation using micro-hydro power turbine (MHP) coupled with a squirrel cage induction generator (SCIG) and a solar photovoltaic panel (PV), which is connected to the common DC bus of three-phase voltage source converter (VSC). The AC terminals of VSC are connected to point of common coupling (PCC) through interface inductors. A battery energy storage system (BESS) is also tied with the common DC bus through a buck-boost converter. The proposed system is mostly suitable to serve the power needs of any small size residential green building situated near a small river or cannel. Control algorithms are proposed for the three-phase VSC and the DC-DC buck-boost converter in order to extract the maximum power from PV array with single-stage conversion, to regulate the AC voltage and frequency at PCC and to improve the power quality. The effectiveness and the robustness of proposed controllers are validated by simulation using Matlab/Simulink at linear and nonlinear loads under different climate conditions.
