Fuzzy Neural Network Control Strategy of Wind Generation and Flywheel Energy Storage Combined System

A new control strategy for a wind generation and flywheel energy storage combined system was proposed. A mathematical model of the system was built based on a vector-controlled induction machine driving a flywheel. The fuzzy neural network (FNN) control method was designed in the system in order to regulate direct current (DC) bus voltage, which was the object of the system. The emulational and experimental results on a wind simulator and flywheel energy storage combined system have verified that proposed energy complementary control can satisfactorily regulate the power of the storage unit to store and release energy and thus to maintain a steady DC voltage from the system.
