AI中文摘要:
本文介绍了QSVT-3PF,这是一种基于量子奇异值变换(QSVT)的求解器,用于处理嵌入了单相网侧换流器(GFM)运行的三相不平衡潮流问题。其贡献有三:1)利用归一化块编码的相域雅可比矩阵,将牛顿校正重新表述为QSVT兼容的逆问题;2)引入正则化奇异值滤波器,以提升病态和应力运行条件下的鲁棒性;3)在集成了单相GFM的IEEE 5节点系统和IEEE 123节点测试馈线上验证了该求解器。测试结果表明,QSVT-3PF在残差收敛、电压分布及最终运行点上与经典牛顿基准一致,证明了QSVT-3应用于大型不平衡配电系统的可行性。
英文摘要:
This letter introduces QSVT-3PF, a quantum singular value transformation (QSVT) based solver for three-phase unbalanced power flow with embedded single-phase grid-forming inverter (GFM) operation. The contributions are threefold: 1) reformulating the Newton correction as a QSVT-compatible inverse problem using a normalized block-encoded phase-domain Jacobian; 2) introducing a regularized singular-value filter to improve robustness under ill-conditioned and stressed operating conditions; and 3) validating the proposed solver on an IEEE 5-bus system and the IEEE 123-node test feeder with single-phase GFM integration. Test results show that QSVT-3PF matches the classical Newton benchmark in residual convergence, voltage profile, and final operating point, demonstrating the feasibility of QSVT-3 for large, unbalanced distribution systems.
