Wireless sensor networks for efficient irrigation system using hybrid pv -wind system

Abstract

This paper describes a novel way of using the hybrid solar and wind energy effectively for pumping solution in rural parts of India. A hybrid generation system consist photo voltaic (PV), wind turbine (WT) and Battery to supply stable power to rural residential loads. DC/DC converters are used to control the power flow to the load and Maximum Power Point Tracker (MPPT) is used for maximum power extraction from the PV and WT and to compensate power fluctuation of renewable energy. When PV and WT generate power is lower than demand power, the Battery is controlled to discharge power to complete the difference of supply and demand power. If PV and WT generate power is higher than demand power, the Battery is charged. This system uses further Wireless sensor network (WSN) for monitoring the moisture content of the soil invarious parts of the cultivation land to maintain the moisture. The system was simulated by using MATLAB/Simulink.
