چکیده
Abstract:The aim of this paper is analyzing the operation of stand-alone wind turbine system with variable speed permanent magnet synchronous generator (PMSG) and a system for storing energy during wind speed and load variations and supply the single phase energy for domestic appliances. The power absorbed by the connected loads can be effectively delivered and supplied by the proposed wind turbine and energy storage system. The stand-alone control featured is constant output voltage and frequency that is capable of delivering to variable load. The PI controller in switch mode rectifier can be replaced with fuzzy control technique to improve the output voltage level. Energy storage devices are required for power balance in the stand alone wind energy systems. Originally the holistic shape of the entire arrangement is achieved together with the PMSG, the AC-DC and DC-DC converter and storage system.
