PMSG wind turbine system for residential applications

This paper analyzes the operation of small wind turbine system with variable speed Permanent Magnet Synchronous Generator (PMSG) and a Lead Acid Battery (LAB) for residential applications, during wind speed variation. The main purpose is to supply 230 V/50 Hz domestic appliances through a single-phase inverter. The required power for the connected loads can be effectively delivered and supplied by the proposed wind turbine and energy storage systems with an appropriate control method. The models of the PMSG, boost converter with a control method for obtaining maximum power characteristic of wind turbine (MPPT), voltage source inverter (VSI) and LAB model with battery state of charge (SOC) control method, are presented. Energy storage devices are required for power balance and power quality in stand alone wind energy systems. Simulations and experimental results validate the stability of the supply.
