| 摘要: |
| 随着分布式能源在电网中比重加大，合理地选择其安装地点对提高电力系统电压稳定性有重要意义。针对传统的失稳模式参与因子对极限诱导分岔失效的缺陷，提出了一种基于节点注入功率空间的电压稳定极限曲面法向量指标用于分布式电源选址。通过理论分析证明了该指标指导选址的合理性。在IEEE39节点系统测试结果验证了其正确性。与传统方法相比，法向量指标可以较好地处理鞍节点分岔和极限诱导分岔两种主要的失稳模式，具有更大的适用范围。 |

| Abstract: |
| With the increase of distributed generation integrated, proper allocation is important to enhance voltage stability of power system. To settle down the drawback of traditional participation factor based allocation method, a normal vector index based on voltage stability limit surface is proposed. The rationality of this index is proved at first. Numerical simulation of IEEE 39 system demonstrates the validity of the proposed method. Compared to the traditional index, normal vector index has a wider range of application because it can deal with the voltage stability critical point of saddle node bifurcation and limit induced bifurcation. |
