摘要
在多机系统中,电力系统稳定器的参数配置是一个复杂的非线性优化问题,可以应用先进的现代内点算法求解该优化问题。本文以Anderson3机9节点系统为例,应用现代内点算法来进行PSS参数优化。通过发电机在不同运行方式下(正常、负荷高峰、负荷低谷)的动态性能仿真结果表明:用现代内点算法进行参数优化后的PSS动态性能优于常规方法设计的PSS,具有一定的鲁棒性。
Parameter setting of Power System Stabilizer in multi-machine power system is a complex non-linear optimization problem. We can solve this optimal problem applying the modern Interior Point Method algorithm. A three-machine nine-bus system of Anderson is optimized as an example and generators are simulated under different load conditions. Results show that the dynamic performance of PSS optimized by IPM algorithm is better than that by conventional methods. It has an improved robusticity.
