Possibility Application of Stand-alone Wind Energy Conversion System under the Climatic Conditions of Iraq

The research included a methodology suitable for the use of wind energy in Iraq for the uses of independent loads, by revealing the importance of wind energy, how to exploit it, its most prominent features and the factors that affect it, as well as analyzing the climatic data related to the speed and direction of the wind, which is useful in revealing the amount of electrical energy produced from The wind is measured in watts / square meters.In this paper, the optimal location in which wind turbines can be used are studied and proposed based on economic criteria in all locations in Iraq in which wind can be used to generate electricity independently from the national grid to operate loads such as water pumps, or for heating, cooling, or energy storge. Developing a mathematical model of wind energy conversion system WECS by using (MATLAB $/$Simulink) consisting of a mechanical system that includes each of the wind turbines with a method of controlling the speed of the turbine rotation while ensuring that the system works at the maximum possible power(maximum efficiency) (maximum power point tracking MPPT) with a gearbox to increase the speed of the turbine connected with a relatively high-efficiency electric generator (parament magnet synchronous generator PMSG) with a power electronics system (Voltage source inverter VSI) with a choice of control method Frequency (Vector control method Field oriented control FOC) to maintain the rotation process while increasing the efficiency of the electrical system.
