| 摘要: |
| 全功率抽水蓄能机组是未来抽水蓄能机组发展的主要方向之一，但是全功率抽水蓄能机组无法向系统提供惯量支撑。传统虚拟惯量控制存在弱阻尼、频率过渡不平滑、无法有效消除稳态频差等问题。为提高系统的惯量裕度和频率安全，提出了一种全功率抽水蓄能机组改进的虚拟惯量控制策略。该策略通过引入 Lead 模块改善传统控制中的负阻尼，通过平滑因子代替传统控制中的死区模块使得频率过渡更平滑，并通过 Anti-Windup 积分模块配合 Washout 滤波器改善传统控制存在稳态频差的问题。同时研究了控制策略基础参数的整定方法，并基于设计实验 (design of experiments, DOE) 下的 ParEGO 多目标优化算法对比例积分微分 (proportional-integral-derivative, PID) 参数进行优化。最后，通过对含有全功率抽水蓄能机组的系统进行仿真分析，结果表明所提控制策略具有良好的频率支撑能力，有助于提高系统的频率稳定性。 |

| Abstract: |
| Full-sized converter pumped storage units represent one of the main development directions for future pumped storage systems. However, such units are unable to provide inherent inertia support to the power system. Conventional virtual inertia control methods suffer from issues such as weak damping, unsmooth frequency transients, and limited capability in eliminating steady-state frequency deviation. To enhance system inertia margin and frequency security, an improved virtual inertia control strategy for full-sized converter pumped storage units is proposed. The proposed approach introduces a Lead module to mitigate the negative damping inherent in conventional control schemes. A smoothing factor is adopted to replace the conventional deadband, resulting in smoother frequency transitions. Additionally, an Anti-Windup integral module combined with a Washout filter is employed to suppress steady-state frequency deviation issues present in conventional methods. Moreover, the tuning methods for the baseline control parameters are investigated, and the PID gains are optimized using a DOE-based ParEGO multi-objective algorithm. Finally, simulation studies on a system incorporating full-sized converter pumped storage units demonstrate that the proposed strategy provides effective frequency support and improves system frequency stability. |
