摘要：This paper presents the dynamic modeling and the simulation results of a renewable energy based hybrid power generation system.In order to meet sustained load demands during varying natural conditions, different renewable energy sources need to be integrated with each other.The paper focuses on the combination of solar cell (SC), wind turbine (WT), hydro turbine (HT), fuel cell (FC) and vanadium redox flow battery (VRB) systems for power generation.As the wind turbine output power varies with the wind speed, the hydro turbine output power with the water speed and the solar cell output power with both the ambient temperature and radiation, a FC system with an UC bank and a VRB system can be integrated to store excess wind, hydro and solar energies under all conditions.Dynamic modeling of various components of this isolated system is presented.Transient responses of the system to step changes in the load, ambient temperature, radiation, wind speed and water speed in a number of possible situations are studied.The results show that the proposed hybrid power system can tolerate the rapid changes in natural conditions and suppress the effects of these fluctuations on the voltage within the acceptable range.
