Abstract

The frequency synchronisation problem of wide-area control from the higher level of networked power systems is considered. We investigate the asymptotic convergence and robustness of the passivity-based distributed averaging control used in damping the inter-area oscillations of power networks and coping with the time-varying power demand. A strict composite storage function is constructed that allows us to quantify the asymptotic convergence rate of the closed-loop system. Furthermore, the power sharing and $L_{2}$ gain performance are utilized as a tool to quantify the impact of time-varying power demand on control areas. We simulate the controller performance on a four-area network which is equivalent to the IEEE New England 39-Bus system.

基于无源性的时变功率需求广域频率同步分布式平均控制

从更高层次考虑了电网广域控制的频率同步问题。研究了基于无源性的分布式平均控制的渐近收敛性和鲁棒性，用于抑制电网区域间振荡和应对时变电力需求。构造了一个严格的复合存储函数，使我们能够量化闭环系统的渐近收敛速度。此外，功率共享和l2 $ l2 $增益性能被用作量化时变功率需求对控制区域影响的工具。我们在一个相当于IEEE新英格兰39总线系统的四区域网络中模拟了控制器的性能。

期刊介绍： IET Control Theory & Applications is devoted to control systems in the broadest sense, covering new theoretical results and the applications of new and established control methods. Among the topics of interest are system modelling, identification and simulation, the analysis and design of control systems (including computer-aided design), and practical implementation. The scope encompasses technological, economic, physiological (biomedical) and other systems, including man-machine interfaces. Most of the papers published deal with original work from industrial and government laboratories and universities, but subject reviews and tutorial expositions of current methods are welcomed. Correspondence discussing published papers is also welcomed. Applications papers need not necessarily involve new theory. Papers which describe new realisations of established methods, or control techniques applied in a novel situation, or practical studies which compare various designs, would be of interest. Of particular value are theoretical papers which discuss the applicability of new work or applications which engender new theoretical applications.
