Sensitivity analysis is carried out with annual load values ranging from 100 kWh to 400kWh, and diesel price ranging from $ 0.5 to $ 1.5. Result is shown in fig. 9. As diesel price or load increases, amount of wind system generation should be increased for optimal operation. For load demands above 175 kWh/day, Wind- Micro hydro- DG - Battery system is the most optimal combination.
