Abstract:-This paper presents a renewable generation, batteries used in renewable-power
systems can undergo many irregular, partial charge/discharge cycles. A stand-alone wind power
system mainly consists of a wind turbine, a permanent magnet synchronous generator, hybrid
energy storage devices based on a vanadium redox flow battery and a supercapacitor, an AC/DC
converter, two bidirectional DC/DC converters, a DC/AC converter and a variable load. This
strategy avoids the necessity of measuring wind velocity, obtaining models or parameters of the
wind turbine and calculating the differentials of the power generated from the wind power system
and from the speed of the generator. The battery charge/discharge control maintains a constant
DC bus voltage. When the battery charging/discharging current reaches the setting threshold, the
charge/discharge control of the supercapacitor is triggered to limit the charging/discharging
current of the battery. The simulation results show that the proposed method can rapidly respond
to variations in wind velocity and load power.
