abstract: since the 1965 power blackout in north america, power companies have made huge efforts to prevent and mitigate cascading power outages in power grids but catastrophic blackouts continued to happen in many countries of the world. at present, ever-growing penetration of intermittent renewable resources in an interconnected power grid will further increase the complexity of the grid, change its dynamic characteristics, and bring more uncertainties and challenges to daily grid operations. the power industry and the research community have been looking forward to new technology enabling “faster-than-real-time” stability assessment and closed-loop control against blackouts.
the presenter will share his visions in this field and introduce three potential approaches to faster-than-real-time stability assessment and control: 1) wide area measurement system (wams) based grid stability assessment; 2) non-iterative semi-analytical solutions of power grid dae models; 3) application of high-performance supercomputers together with techniques on spatial and temporal partitions of the power grid dae model for faster computation.
