| 摘 要： | 将模拟植物生长算法应用于电力系统无功优化。提出了将无功补偿容量、变压器主变抽头和发电机节点电压3种类型的控制变量采用统一模式转化成整型变量的方法。对Ward-Hale 6节点、IEEE 30节点系统的计算分析及连续型发电机节点电压的离散点个数对计算结果影响的探讨表明:兼具随机性和方向性搜索机制的模拟植物生长算法具有较强的全局搜索能力,且使用方便,为解决电力系统无功优化问题提供了一种新途径。

| Abstract: | A novel plant growth simulation algorithm is proposed for reactive power optimization of power system. A unified pattern to transform three kinds of control variables, i.e., reactive power compensation, transformer tap and nodal voltage of generator, into integer variables is also presented. The results of calculation and analysis of Ward-Hale 6-bus system and IEEE 30-bus system as well as those of the research on the influence of the amount of discrete points of generator's nodal voltage on calculation result show that the plant growth simulation algorithm, which possesses both random and directional search mechanism, has good global search ability and can be used conveniently. It creates a new field for reactive power optmization of power system. |
