This paperpresents an ANFIS based adaptive sliding mode control (ASMC) of a standalone single phasemicrogrid system. The proposed microgrid system integrates a micro-hydro turbine driven single-phase twowinding self-excited induction generator (SEIG) with a wind driven permanent magnet brushless DC(PMBLDC) generator, solar photo-voltaic (PV) array and a battery energy storage system (BESS). Theserenewable energy sources are integrated using a single-phase voltage source converter (VSC). The ASMCbased control algorithm is used to estimate the reference source current which controls the single-phase VSCand regulates the voltage and frequency of the microgrid in addition to harmonics current mitigation. Theadaptive sliding mode control with ANFIS is used to maintain the energy balance among wind, micro-hydro,solar PV power and BESS, which controls the frequency of standalone microgrid. Simulation results fromMATLAB/SIMULINK of the proposed microgrid shows that the grid voltage and frequency are maintainedconstant while the system is following various changes in dynamic state such as sudden change in windspeed, changes in solar insolation level and changes in loads.
