This paper presents the control strategy for a stand-alone wind turbine system connected to batteries is presented in this paper. The wind turbine system uses permanent magnet synchronous generators (PMSG). The control strategy consists of optimum power extraction based on particle swarm optimization (PSO) and loads voltage control based on multi-objective PSO (MOPSO). The optimum power extraction functions to get optimal power at each wind speed based on voltage and current of converter through the control of the converter duty cycle. While MOPSO will tuning parameter of the proportional integrator (PI) controller which will regulate the bidirectional converter through duty cycle setting so that the dc-link voltage can be held according to the reference value. This control strategy is tested for slowly and rapid wind speed changes. Based on the test results, this control strategy has good performance. The dc-link voltage can be maintained constant at 400V and the power can be extracted optimally even though the wind speed fluctuates rapidly. © 2020 Institut za Arhitekturu i Urbanizam Srbije.
