中文摘要:
      鉴于目前电力系统无功备用优化方法较少涉及暂态电压稳定性,提出一种同时提高电力系统静态/暂态电压稳定性的无功备用优化模型,该模型首先基于数据密度提出一种无功电压控制分区方法,分别在静态/暂态电压的薄弱区域内定义静态/暂态无功备用,然后结合所建立的两个目标建立多目标无功备用优化模型,最后提出一种基于多阶段的多目标优化求解方法。通过求解所建模型,获得能够同时提升系统静态/暂态电压稳定性的无功备用配置方案。对IEEE 39节点系统的仿真分析证明了所提方法的有效性。
英文摘要:
      Current reactive power reserve dispatch method usually neglects the transient voltage stability. Therefore, reactive power reserved optimal model was proposed to enhance both the static and transient voltage stability in power systems. First, a voltage control area method was proposed based on density peaks. Then, the static and transient reactive power reserve were defined for the vulnerable areas, respectively. Furthermore, a multi stage solution was proposed to solve the proposed multi objective optimization problems. The results of the IEEE 39 bus system demonstrate that proposed method can enhance static and transient voltage stability simultaneously.
