带宽参数自适应调整的压缩空气储能线性自抗扰平滑并网控制策略OA
Linear Active Disturbance Rejection Smooth Grid-connected Control Strategy for Compressed Air Energy Storage with Adaptive Adjustment of Bandwidth Parameters
压缩空气储能CAES(compressed air energy storage)作为一种具有较大发展潜力的储能技术,具有规模大、寿命长、环保等优点.但由于其容量较大,因此在接入电网时,如果不满足电压相位、幅值、频率均与电网相同的条件,就会出现并网冲击电流过大威胁电力系统安全稳定运行的问题.为此,在相比于传统比例积分 PI(proportional intergral)控制更为精确的线性自抗扰控制LADRC(linear active disturbance rejection control)的基础上,提出了一种带宽参数可以自适应调整的LADRC策略自适应线性自抗扰控制A-LADRC(adaptive linear active disturbance rejection control)以实现平滑并网.最后通过仿真实验和硬件在环实验对所提控制策略进行了验证,并选取了合适的调节参数,结果表明,所提自适应控制策略能够有效减小并网冲击,实现平滑并网,为CAES安全接入电网提供了新的解决方案.
Compressed air energy storage(CAES),as an energy storage technology with great development potential,has the advantages of large scale,long life and environmental protection.However,due to its large capacity,if the voltage phase amplitude and frequency are not the same as those of the power grid when it is connected to the power grid,there will be a problem that the grid-connection impulse current is too large and threatens the safe and stable operation of the power system.Therefore,based on linear active disturbance rejection control(LADRC),which is more accurate than traditional PI control,a linear active disturbance rejection control strategy with adaptive adjustment of bandwidth parameters is proposed to achieve smooth grid connection.Finally,the proposed control strategy is verified by simulation experiment and hardware-in-the-loop experiments,and appropriate adjustment parameters are selected.The results show that the proposed adaptive control strategy can effectively reduce the impact of grid-connection and achieve smooth grid-connection,providing a new solution for the safe access of compressed air energy storage to the grid.
