Great challenges for operating power systems reliably are posed by the increasing energy demand, renewable penetration, and extreme weather due to climate change. As information technology and networks play major roles in transforming how power grid is operated, security issues from cyber-physical intrusion also become critical. In this talk, we focus on the role of monitoring systems in ensuring reliability and security of power grids. Firstly, we discuss outage detection in large-scale power distribution networks. A system that combines optimally deployed real-time power flow sensors and non-real-time load forecasts is proposed. Next, we discuss the fundamental limits of monitoring systems in detecting cyber-physical attacks. An open problem of finding sparsest unobservable attacks is solved.
