摘要
基于飞轮储能系统和双向DC/DC都是能量双向流动的特点,提出一种基于双向DC/DC的飞轮储能系统控制策略,包括充电时的恒流、恒压、转速闭环复合控制策略和放电时的二自由度PI控制策略,给出飞轮储能系统组成结构及控制框图。仿真和实验结果表明,所提基于双向DC/DC的飞轮储能系统控制策略在充电方面解决了传统控制策略的局限性,控制灵活;在放电方面具有更好的抗负载干扰和目标值跟随能力。
The fl ywheel energy storage and two-way DC/DC are two-way fl ow of energy systems. This paper proposed a fl ywheel 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 fl ywheel energy storage system. The simulation and experimental results show that the bidirectional DC/DC control strategy of the proposed fl ywheel energy storage system overcomes the limitations of traditional charge control strategy with fl exible control, while in the aspect of discharge, the control strategy is with the ability of better resistance to load interference and target value following.
