深入研究了观测器驱动的简化复制(ORC)在风电场广域振荡减振控制(WFS)中处理数据丢包的应用。ORC技术试图利用间歇观测下的标称动态信息来模拟电力系统的行为。此简要介绍了ORC的直接绩效衡量标准。为此，给出了一个关于两个函数乘积上的积分范数的界的标准引理，并用Hölder不等式进行了证明。在此引理的基础上，给出了存在数据丢失和理想通信情况下电力系统状态差在采样区间内范数上界的表达式。当在相对意义上评估时，这样的界限将有助于系统操作员从衰减性能的角度执行在线事故筛选和排序，而无需运行昂贵得令人望而却步的时域仿真。此外，对于常规的反馈控制，也推导出了这样的界。数据丢失采用Gilbert-Elliott模型进行建模。分析结果通过一个16机、5个区域的新英格兰-纽约系统的时域仿真得到验证，该系统具有两个基于双馈感应发电机的WF。
Insight into the application of observer-driven reduced copy (ORC) to deal with data packet dropout during wide-area oscillation damping control through wind farms (WFs) is developed. The ORC technique tries to emulate the behavior of the power system by using the information of the nominal dynamics under intermittent observation. This brief presents a direct performance measure for ORC. To that end, a standard lemma relating the bound on the norm of the integral over the product of two functions is presented, which is proven using Hölder’s inequality. Based on the lemma, an expression is derived for the bound on the norm within an inter-sample interval for difference between the power system states in presence of data dropout and that under ideal communication. Such a bound, when evaluated in a relative sense, would be useful for system operators to perform online contingency screening and ranking from damping performance standpoint without running prohibitively expensive time-domain simulations. In addition, such a bound is also derived for the conventional feedback control (CFC). The data dropout is modeled using the Gilbert-Elliott model. The analytical results are validated using time-domain simulation of a 16-machine, 5-area New England-New York system with two doubly fed induction generator-based WFs.
