摘要
本文提出了一种利用线性规划和灵敏度分析法求解校正电力系统紧急状态算法,利用线性规划的最终单纯形表,推导了灵敏度公式,从而大大减少了校正计算中线性规划的迭代次数,提高了计算速度。本算法对IEEE30节点实验系统进行了计算,实验表明本算法快速而可靠。
By making use of linear programming and its sensitivity analysis, an algo rithm for calculating and rectifying the emergency state of power systems is put forward. Using the linear programming ultimate simplex list, the sensitivity formula are derived, thus greatly reducing the number of iteration of linear programming and enhancing the calculating speed. An experimental calculation of IEEE 30-node system with this algorithm is carried out and the results show that the algorithm is reliable and fast.
