Abstract


This paper demonstrates a water pumping hybrid power system design. The proposed system was designed for water related applications in Sharjah (Latitude 25.〖29〗^oN and Longitude 〖55〗^oE), United Arab Emirates. The proposed water hybrid system has two primary renewable power systems: solar PV panels and wind turbines. Perturn and Obsreve mechanism was included in the components of the solar power sytem. The proposed hybrid system considers the changes in weather conditions (humidity, wind speed, and temperature) since wind speed affects the performance of the wind turbines and solar panels are affected by solar irradiance. The purpose of using this hybrid power water pumping system is providing enough and sufficient supply of water to isolated areas in Sharjah using renewable energy power sytems to covert the continuous demand since the climate is hot in Sharjah most of the year with few rainy days in winter (December till March). The following components are involved in the proposed design: battery (to store the power from solar panels), voltage regulator circuit (for getting stable DC voltage), three-phase rectifier (to convert the reduced AC voltage to DC), three-phase transformer (for reducing the obtained AC voltage), and DC electric motor (the main output of the proposed water pumping system). The proposed water pumping system relies on Neural Network blocks to achieve weather forecasing by obtainging solar irradiance values from the input temperature, wind speed, and humidity in a span of five years. Both MATLAB and Simulimk are used simulate the performance of the proposed system under different weather conditions by changing the values according to the measured weather conditions values over five years.
