Most of power systems experience a transient mode. In a special case, the operation of solar panel and wind turbine is depended to solar irradiance and wind speed. In addition, maintenance dc-link voltage and output AC voltage regardless variations of wind speed and solar irradiation can be a challenging topic. In this paper, a new strategy based on the stability of dc-bus voltage for a hybrid power system is proposed. Firstly, the operation of dc-bus voltage for a standalone hybrid power system consists of solar panel and wind turbine is investigated. In this case, a PI controller is used to regulating at its reference value. Finally, the performance of dc-link voltage in a stand-alone hybrid system included a solar PV, wind turbine, battery, and the fuel cell is studied. Furthermore, the Fuzzy logic controller is used as a power management energy in this case. The MATLAB/Simulink and SimPowerSystems software packages are used to model a proposed stand-alone haybrid power system. Simulation results show that proposed strategy has better performance under fast variation of irradiance.
