| 摘要: |
| 提出了一种可同时考虑静态与动态无功补偿的无功补偿优化模型.在对负荷裕度的概率分析的基础上用最小二乘法构造电压崩溃的概率模型.对电压崩溃动态过程进行概率分析,对暂态和稳态过程中对电压稳定和电压质量有所影响的因素进行经济量化,提出了稳态运行费用和暂态运行费用的总和最小为目标函数的无功补偿综合优化模型.在此基础上通过动态仿真与静态分析相结合的方法逐步迭代求解最优补偿容量.华南某电网实际算例中的应用表明,综合无功补偿优化的结果具有最小的年运行费用和最大的故障后负荷裕度,可以显著改善受端系统运行的经济性和安全性. |

| Abstract: |
| A reactive power optimization model is presented,which considers both static and dynamic reactive power compensation. The probability model of voltage collapse is constructed based on the load margin probability analysis using the least square algorithm. The comprehensive reactive power optimization model is proposed based on the probability analysis of the dynamic voltage collapse process and the economic quantification of influential factors on voltage stability and quality during the transient and steady... |
