Optimal Choosing of Hybrid Renewable Source for Varying Condition for Effective Load Managemet

The goal of this thesis is to evaluate the performance of a hybrid solar wind, fuel cell and battery energy system through Mat lab simulation studies. The main objective of this study is the development of dynamic models of an off grid (standalone) solar wind turbine, fuel cell and battery system which is used for charging and discharging. Maximum power can be extracted from PV module by using Maximum Power Point Tracking (MPPT) by controlling the duty cycle of a switch. The developed model of the wind energy conversion system consists of dynamic models for a wind turbine as well as induction motor or Permanent Magnet Synchronous Machine. In this thesis we have to control the sources depending upon the load condition. The solar installation cost is less than the remaining sources. So solar supplies the load continuously. If solar cell generated power is not sufficient, then the wind supplies. And if solar and wind generated power are not sufficient, then fuel cell will be operated along with solar and wind. A battery which is used for backup purpose will supply if solar, wind, fuel cell generated power is not sufficient.
