1七级变频器的PI控制器的优化以辅助电网交互式RES控制器显示文摘随着能源需求的巨大增长,当前的电力系统急需适应新的要求,能将再生能源接入电网从而整合利用可再生能源。多级变频器(MLI)可在两种不同的模式下实现这个功能,即发电模式(独立模式)和补偿器模式(STATCOM)。目前,对于不同工况的单一类型负荷的变化,如无功负荷的变化,优化控制器增益的研究很少。这类负荷的稳定性不好的问题急需解决。因此,一个适用的优化算法尤显重要。本文介绍了一种基于优化辅助PI控制器的七级变频器控制设计算法。在所提出的算法中,PI控制器的增益是根据系统的运行条件,通过采用混合方案,即龙形更新的灰色优化器(GD-LU),对增益进行动态调整,使参考信号与故障信号之间的误差最小,以便所提出的优化PI控制器可以获得更好的动态性能。提出的算法是灰狼优化(GWO)和蜻蜓算法(DA)的组合版本。最后,对所提出算法的性能与其他先进的模型就误差方面进行了比较和验证。GAYATHRI DEVI K S SUJATHA THERESE P 2021Journal of Central South University2021,28,1:2
