| 摘 要： | 在传统内点法的基础上,提出了一种求解无功优化的支路追加内点法——将线路和变压器模型整合为统一的支路模型;采用支路追加方式来实现内点法中雅克比矩阵和海森矩阵的求解;将优化模型中目标函数与等式约束的求导过程合并。通过以上改进措施,有效地降低了无功优化的公式推导和编程工作量,提高了算法的效率。最后通过IEEE14、IEEE30和IEEE118等系统的仿真计算,验证了该算法的快速性和有效性。

| Abstract: | Based on the traditional interior point method(IPM),one branch-adding IPM for reactive optimization is proposed.Firstly,the models of line and transformer are integrated as a unified branch model.Secondly,branch-adding method is adopted to calculate the Jacobian matrix and Hessian matrix in IPM.Thirdly,the derivations of objective function and equality constraints are combined.The above improvements decrease the formula derivation and programming workload for reactive optimization,and improve the algorithm ... |
