A Coordinate Penality Method for Improving Convergence of Optimal Power Flow by Newton Approach

提出了用协调惩罚技术改善牛顿法最优潮流收敛性。根据ｌａｇｒａｎｇｉａｎ函数的梯度，自动计算乘子罚函数的因子，可以避免优化过程的振荡，提高最优潮流算法的可靠性，缩短最优潮流的优化时间、本文对ＩＥＥＥ５，１１，１４，３０节点系统和我国安徽４０节点系统的算例表明协调惩罚技术用于牛顿法最优潮流取得了明显效果。

A coordinate penality method is put forward to imjprove convergence of optimal power flow by newton approach. Automatically calculating the penality factor by gradient of optimization can raise the ability of optimal power flow and shorten its time. The OPF for IEEE5, 11, 14, 30 buses system and Anhui 40 buses simplied one are calculated. The obvious result of Newton approach with the method of coordinate penality is proved.
