原对偶内点法和预测校正原对偶内点法在电压稳定裕度计算中的应用比较

Comparison of PDIP and PC PDIP on Analyzing Voltage Stability Margin

  • 摘要: 以交直流混合系统电压稳定裕度为研究对象, 采用原对偶内点算法进行全局寻优;并在此基础上引入预测校正, 通过协调解的可行性和最优性之间的关系提高算法的收敛速度。以IEEE-14、30节点系统为例, 通过对影响算法关键因素σ的分析, 比较了原对偶内点法和预测校正原对偶内点法的计算精度和速度, 验证了本文算法的可行性并对两种算法的全局寻优能力做了比较, 在相同的约束条件下都得到了满意的结果, 且计算速度与系统规模关系不大。

     

    Abstract: In order to calculate voltage stability margin of hybrid AC/DC system, the primal dual interior point(PDIP)is applied in global optimization. Then a predictor corrector technology is adopted to improve the convergence speed by coordinating the optimality and feasibility. The accuracy and calculation speed of the two algorithms are compared through analyzing the key factor of σ, and the feasibility and the ability of global optimization of both algorithms are compared by taking IEEE 14 bus and 30 bus system as example. Satisfying results are obtained under the same constraints, and also show that the calculation speed has no relation to system scale.
