Abstract: The flywheel energy storage and two-way DC/DC are two-way flow of energy systems. This paper proposed a flywheel energy storage system based on bidirectional DC/DC control strategy, including charging constant current, constant voltage, closed-loop speed compound control strategy and two degrees of freedom PI discharge control strategy. This paper gave the composition structure and control block diagram of the flywheel energy storage system. The simulation and experimental results show that the bidirectional DC/DC control strategy of the proposed flywheel energy storage system overcomes the limitations of traditional charge control strategy with flexible control, while in the aspect of discharge, the control strategy is with the ability of better resistance to load interference and target value following.
Key words: flywheel energy storage system; bidirectional DC/DC; compound control strategy; two degrees of freedom PI control strategy
