一最不轮流出现摆平途径在这份报纸被开发识别指数的恢复宽区域的力量系统的动态负担模型。非线性的优化问题被分解到二个线性最少的广场问题,并且以一个轮流出现的方法解决了。然后,为用分离 Fourier 变换的数字衍生物计算的一个新算法被建议在参数评价的过程稀释噪音的效果。基于估计的动态负担特征,电压稳定性上的应用程序被分析。最后,数字并且实验室例子被进行表明建议方法的有效性。
An alternating least squares approach is developed in this paper to identify the exponential recovery dy- namic load model of wide-area power systems. The nonlinear optimization problem is decomposed to two linear least squares problems, and solved in an alternating way. Then, a new algorithm for numerical derivative calculation using dis- crete Fourier transform is proposed to attenuate the effect of noises in the process of parameter estimation. Based on the estimated dynamic load characteristics, the application on voltage stability is analyzed. Finally, numerical and laboratory examples are conducted to demonstrate the effectiveness of the orooosed methods.
