Abstract: Wideband oscillation events, with frequencies ranging from several hertz to several kilohertz, have been frequently reported in modern power systems, posing significant challenges to grid stability and sustainability. In response, technologies for oscillation monitoring and analysis have received increasing attention. However, most existing technologies still rely primarily on traditional wide-area measurement systems, which struggle to meet the requirements for wideband oscillation monitoring. This paper first presents a comprehensive review of recent wideband oscillation events reported worldwide, highlighting their causes and adverse impacts on equipment security and system stability. Subsequently, a novel framework for a wideband dynamic monitoring and control system (WDMCS) is proposed, along with detailed descriptions of its principal components and key functions related to wideband oscillations. Finally, a demonstration of WDMCS has been developed, and its effectiveness has been validated through tests conducted on a hardware-in-the-loop platform. The potential and challenges of the proposed system in various domains of power system stability assessment and control are also discussed.
