| 摘 要： | 提出了一种在线求解电力系统无功优化问题的方法。该方法基于新的差异进化（DE）算法和并行计算技术，在PC集群上实现优化。IEEE118节点系统的算例表明：DE算法尽管简单，但可快速收敛到近似最优解；采用并行差异进化和适当规模的PC集群，可大大缩短电力系统无功优化的计算时间，使之满足在线应用的需要。

| Abstract: | An approach to on-line optimization of reactive power flow is proposed. It is based on a new branch of evolution algorithm named differential evolution (DE) and parallel computing techniques implemented on a PC-cluster. Case study on the IEEE 118-bus system shows that DE, simple as it is, converges fast to the approximate optimal solution. When DE is parallelized and executed on a PC-cluster of moderate size, it is possible to shorten the computing time of reactive power optimization within an acceptable scope, which is needed for on-line application. |
