Use of real time simulation to validate primary frequency control with wind turbine

In this paper, a primary frequency control strategy based on fuzzy logic designed for variable speed wind generator is proposed. The fuzzy logic supervisor ensures a regular primary reserve on a large range of wind speed without any wind speed measurement. This supervisor controls simultaneously the generator torque and the pitch angle to keep the primary reserve; it determines in real time the generator power reference value. A methodology to implement in real time the fuzzy logic supervisor is proposed to reduce the computational time. This control strategy is tested on an original hybrid simulator composed of actual equipment connected with a real-time simulator via a high band width amplifier.
