Wind And Photovoltaic Thermal Power Production For Lift Irrigation

Abstract

The main objective of this study is to show the ground-water sources for full year farming and avoiding idle time by using wind and photovoltaic thermal (PVT) hybrid water pumping system for irrigation application and its viability.

Unlike the previous optimization procedure which only consider the demand for hydraulic energy; this paper presents all the relevant system elements and their characteristics will be analyzed. The system elements are wind and Photovoltaic thermal power production for water pumping system, climate and variation of total head, soil, crops types and irrigation method. All this have directly influence on the demand load for water pumping and it enables us to find the optimal power required for water pumping systems. Also by using photovoltaic thermal power production rather PV modules alone, increased by maintaining the temperature of the modules. The paper approaches through mathematical modeling and use Microsoft Excel with combination of MATLAB program for simulation. In the simulation program the water pumping system elements and their relation are integrated and the optimal nominal electric power generated by the selected hybrid system is generate the required energy of 2831.7kWh/year . It was concluded that the hybrid system is viable with economic background evaluated depend on Net Present Value (NPV), Internal Rate of Return (IRR); Benefit Cost ratio (B/C), and payback period; which results $3409.57, 9%, 1.8 and 5 year respectively.
