摘要
将同伦延拓方法用于求解电力系统病态潮流方程的解,并提出一种求解同伦曲线的新方法。这种方法可以修改迭代初值以及改变雅克比矩阵的奇异性,使其进入收敛范围。对典型病态系统的数值计算的比较表明了该算法的有效性。
This paper makes homotopy continuation method for power system load flow calculation. The initial condition of power systerm load can be modified by a new approach based on the homotopy continuation method for the new initial condition, the iteration was convergent by means of the conventional load flow calculation. The case study was made at special ill-conditions system and the validity was proved.
