| 摘要: |
| 介绍了电力系统中以发电费用最小为目标的最优潮流计算的可变容差法。该方法无需求解目标函数的导数，利用数值搜索优化机制，可较好地获得最优解。实例分析表明，与现有的模型求解方法相比，可变容差法具有较好的寻优效果。可以作为电力系统最优潮流计算的一种补充方法。 |

| Abstract: |
| Flexible tolerance method,which handles the optimal power flow model for achieving the minimum generation cost,is proposed.By using its numerical value search mechanism,the opti-mum solution can be obtained without the derivative calculation of goal function.Computation sam-ples show that,compared with the existing methods,flexible tolerance method has better effect in optimum solution search and can be considered as a supplementary way to calculate the optimal power flow of power systems. |
| Key words: power systems,power flow calculation,optimal power flow,flexible tolerance method |
