Abstract
In interconnected modern power systems, renewable energy sources, HVDC transmission lines, and energy storage devices are growing after being installed globally with development in power electronics and communication technology. Low-frequency inter-area oscillations (0.2–0.8 Hz) have a severe influence on the operation of an interconnected power system due to the numerous generators. This paper provides a comprehensive literature review of the wide-area measurement system-based wide-area damping control systems with operational uncertainties, including signal communication effects, such as time delay, packet loss, noise, and disorder, , on damping control performance. Different wide-area damping control techniques are investigated, emphasizing their advantages inadequacies and categorized according to vital features. In recent years, the resilience of wide-area damping control systems to cyber-physical attacks has recently been brought back to the researcher’s consideration because of the opportunities produced by information-communication technologies and the renewed interest in installing renewable energy sources. This paper provides recent developments in methods of damping performance enhancement that deserve further study in cyber-physical power systems. Overall, the present study is helpful for academicians and researchers to identify the objectives in the area of cyber-physical power systems to enhance the wide-area damping performance.
