This paper presents the control strategy of the permanent magnet synchronous generator (PMSG) for stand-alone wind power generation system with battery energy storage management during wind speed and load variations. The complete system includes a PMSG connected to the load through a fully controlled back to back PWM converter and an intermediate DC link capacitor which is connected to a battery energy storage system through a bidirectional dc-dc converter. The control strategy to a stand-alone wind conversion system is divided into three parts: the control of PMSG side PWM converter employed to generate the maximum power (MPPT) during wind variations, a control strategy by bidirectional dc-dc converter developed to manage the power flow battery in different wind and load conditions, and a load side PWM converter controller is achieved to regulate the load voltage and frequency under varying wind and load conditions. The model system is developed in Matlab/Simulink environment with Power System Blockset (PSB). Simulation results confirm the effectiveness and performance of the control strategy.
