Fig. 2 Solar Irradiance Profile of Pathanpara Solar radiation data for Pathanpara village is obtained from the NASA Surface Meteorology and Solar Energy web site [4]. The location under consideration is at latitude of 11°52' N and longitude of 75°25! E. The annual average solar radiation for this area is 5.53kWh/m*/d. Fig. 2 shows the solar resource profile over a one-year period. Fig. 1 Proposed Renewable Energy Hybrid System The proposed hybrid renewable consists of a Micro Hydro turbine, wind turbine and solar photovoltaic (PV) panels. Diesel generator, battery and inverter are included as part of back-up and storage system. The proposed system is shown in Fig. 1. The project lifetime is estimated at 20 years. The annual interest rate is fixed at 7.25%. The proposed area is Pathanpara, a remotely located village in Kannur district, Kerala. A. Solar resource TABLE 1 COMPONENTS USED The Optimization output from HOMER is shown in fig. 6. The most optimal combination of hybrid system is shown in Table 2. The total annual contribution of each generating system is shown in fig. 7. The monthly average stream flow profile for the proposed site is shown in fig. 4 Fig. 4 Annual Stream flow Profile Where v and vo are wind speeds at 30 m and 5 m, H and Hy are 30m and 5m heights and a is a measure of surface friction, taken as 0.13. The annual Wind Profile is shown in fig. 3 List of Component sizes considered for Optimization is given in table 1. Fig. 8 Monthly Average Electric production Chart 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. Fig. 7 Annual Power Contribution from each source
