中文摘要

大多数电力电子变换器负载表现为恒功率负载(CPL),其小信号负阻抗特性会降低系统稳定性。本文研究了利用人工智能技术优化主动阻尼控制策略,以抑制交直流馈线系统中的不稳定现象,并避免负载侧补偿对负载性能的影响。

English Abstract

Most electrical power system loads are actively controlled power electronics converters behaving as constant power loads. These loads resemble a small-signal negative impedance that can directly degrade the system stability margin and performance. The active damping approach is widely used for instability mitigation. However, if the mitigation is applied at the load side, it can affect the load pe...

该研究针对恒功率负载(CPL)引发的系统振荡问题,对阳光电源的储能变流器(PCS)及微电网解决方案具有重要参考价值。在PowerTitan等大型储能系统或微电网应用中,当系统接入大量电力电子设备时,负阻抗效应易导致并网点失稳。引入AI优化主动阻尼算法,可提升系统在弱电网环境下的鲁棒性,优化iSolarCloud智能运维平台的故障预测能力。建议将此AI控制策略集成至PCS底层控制逻辑中,以增强系统在复杂负载工况下的动态稳定性。
