计及安全约束的最优潮流计算

Optimal power flow calculation with safety constraint

从电力系统优化运行的角度出发,研究计及安全约束的电力系统最优潮流问题.使用Power World Simulator可视化软件,以3机9节点典型系统为例,完成了计及安全约束的最优潮流计算,对优化结果和基本潮流进行了对比分析.结果表明,计及安全约束的最优潮流的系统的安全性更高,线路负载更均衡,节点电压更接近电压基准值.

From the point of view of optimal operation of power system, the optimal power flow of power system with security constraints is studied. Using the Power World Simulator visualization software, an example of 3 machines and 9 nodes typical system is given, and the optimal power flow calculation with security con- straints is completed. The optimization results and the basic power flow are compared and analyzed. The re- suits show that the system is safer, the line load is more balanced, and the node voltage is closer to the volt- age reference value.
