摘要
基于电力系统PQ节点可控性理论,提出了一种降阶的雅可比矩阵,并在单恒定功率负荷-∞系统上进行了论证,在多机系统上进行了计算,结果表明此模型是可靠的。最后通过对Ward-Hale6节点系统的计算,对减负荷点的选择进行了探讨。
The paper proposes a reduced Jacobi matrix based on the theory of the PQ node controllability.t is verified at a single constant power load-infinite system , the result shows that the model is reliable. At last, the author investigate the optimal load-shedding node through the calculation on the Ward-Hale 6-node system.
