Countries around the world are transitioning from conventional power systems dominated by synchronous generators towards low-carbon resources, characterized high levels of converter-interfaced (CIGs). With this transformation, hundreds or even thousands fast electronic devices will be added to grid as CIG penetration increases, thus making system dynamic response progressively faster and more c...

Modern power grid is a generation mix of conventional facilities and variable renewable energy resources (VRES). The complexity such with has routed the utilization infrastructures involving phasor measurement units (PMUs). This to have access real-time information. However, traffic digital information communication potentially vulnerable data-injection cyber attacks. To address this issue, med...

In recent years, subsynchronous resonance (SSR) has frequently occurred in DFIG-connected series-compensated systems. For the analysis and prevention, it is of great importance to achieve wide area monitoring incident. This paper presents a Hankel dynamic mode decomposition (DMD) method identify SSR parameters using synchrophasor data. The basic idea employ DMD technique explore subspace matric...

Large-Scale Particle Image Velocimetry (LSPIV) is an effective method for the measurement of the river surface flow velocity. For the wide cross-section river, in the near-field area of river surface image there are small and clear targets. But the flow tracers are almost invisible in the far-field area because of the resolution limit of one single video camera, which makes it difficult to comp...
