Dynamic Behavior of Stand-Alone Parallel Operation System Using Two Wind Turbine-Generators

This paper discusses the dynamic behavior of the stand-alone parallel operation system using two wind turbine-generators by our dynamic simulation model. The stand-alone parallel operation system is composed of two Darrieus-Savonius hybrid turbines, two load induction generators, one inverter, batteries, and one controller. This system is mainly operated at the maximum power coefficient points of two parallel turbines by the inverter frequency control for a simple system composition and high power extraction. The computed results of the dynamic behavior of the system to various wind speed changes shows that our control scheme of the parallel operation system is effective.
