本文是一个两部分系列的第二部分，讨论了一种鲁棒无迹卡尔曼滤波器(UKF)的实现问题和测试结果，该滤波器用于含非高斯同步相量测量噪声的电力系统动态状态估计。提出并系统地讨论了广义最大似然型鲁棒UKF（GM-UKF）的参数整定问题。通过对IEEE39节点系统的仿真，评估了该系统在不同情况下的性能，包括：i）在厚尾分布下出现两种不同类型的噪声，即真实功率和无功功率测量的拉普拉斯或柯西概率分布；㈡观察和创新异常值的出现；iii）由于通信故障导致PMU测量损失的发生；iv）网络攻击；强系统非线性。并与UKF和广义最大似然型鲁棒迭代EKF（GM-IEKF）进行了比较。仿真结果表明，GM-UKF在所有场景下的性能都优于GM-IEKF和UKF。特别地，当系统在应力条件下运行时，由于系统非线性，GM-IEKF和UKF发生发散，而我们的GM-UKF收敛。此外，当功率测量噪声服从Cauchy分布时，我们的GM-UKF收敛到一个状态估计向量，表现出比GM-IEKF更高的统计效率；相比之下，UKF未能收敛。最后，在结束语部分讨论了拟议的GM-UKF的潜在应用和未来的工作。

英文摘要：
  This paper is the second of a two-part series that discusses the implementation issues and test results of a robust Unscented Kalman Filter (UKF) for power system dynamic state estimation with non-Gaussian synchrophasor measurement noise. The tuning of the parameters of our Generalized Maximum-Likelihood-type robust UKF (GM-UKF) is presented and discussed in a systematic way. Using simulations carried out on the IEEE 39-bus system, its performance is evaluated under different scenarios, including i) the occurrence of two different types of noises following thick-tailed distributions, namely the Laplace or Cauchy probability distributions for real and reactive power measurements; ii) the occurrence of observation and innovation outliers; iii) the occurrence of PMU measurement losses due to communication failures; iv) cyber attacks; and v) strong system nonlinearities. It is also compared to the UKF and the Generalized Maximum-Likelihood-type robust iterated EKF (GM-IEKF). Simulation results reveal that the GM-UKF outperforms the GM-IEKF and the UKF in all scenarios considered. In particular, when the system is operating under stressed conditions, inducing system nonlinearities, the GM-IEKF and the UKF diverge while our GM-UKF does converge. In addition, when the power measurement noises obey a Cauchy distribution, our GM-UKF converges to a state estimate vector that exhibits a much higher statistical efficiency than that of the GM-IEKF; by contrast, the UKF fails to converge. Finally, potential applications and future work of the proposed GM-UKF are discussed in concluding remarks section.
