摘要
分析了电力系统电压无功实时优化控制中出现的不可行问题，通过引入模糊约束，从一个新的角度对不可行问题进行了处理，最终获得尽量靠近原不等式约束空间的解。文中结合原对偶内点法的特点提出了不可行问题的探测和处理方法，并用模型系统和华东电力系统的实际数据进行了验算。结果表明，文中所提的方法可以有效地探测和处理优化过程中的不可行问题。
The infeasibility problem in voltage/reactive power optimization is analyzed in this paper, and this problem is handled with fuzzy constraints to obtain a solution as close as possible to the original space. The infeasibility detection and handling strategy is discussed while the prime\|dual interior point method is used. The test results of 12 nodes system and East\|China power system illustrate that the proposed method can effectively handle and detect infeasibility problem caused by bottleneck constraints and is fast to get a reasonable solution.
