Abstract

This paper analyzes the operation of a stand-alone wind turbine system with variable speed Permanent Magnet Synchronous Generator (PMSG) and a Lead Acid Battery (LAB) for energy storage, 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 control method for obtaining maximum power characteristic of wind turbine (MPPT), monitoring voltage and battery state of charge (SOC) to ensure optimum charging conditions for LAB, 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.
