Recent developments in renewable energy sources have shown that they can contribute more to the grid along with conventional sources. In order to synchronize with the grid and to meet the ever increasing load demands during varying atmospheric conditions, various renewable energy sources needs to be integrated with each other. This paper describes modeling and simulation of a renewable energy based hybrid system connected to the grid through a intermediate DC bus. To optimize the power output from each of the renewable energy sources, Maximum power point tracking (MPPT), algorithm is used along with a buck boost converter to obtain a stable voltage. The output from the dc bus is used to drive a DC motor coupled with an alternator to supply ac power, which can be either connected to the grid or directly to the loads. The renewable energy sources used are wind turbine, and a PV cell. The design of the proposed hybrid system will effectively manage the optimal utilization of both the energy sources and ensures reliability in power supply during varying atmospheric as well as load conditions.
