The electric grid is currently undergoing a significant renovation process towards the so-called smart grid, featuring larger hosting capacity, widespread penetration of renewable energy sources, better quality of service, and higher reliability. One of the major aspects of this modernization is the widespread deployment of dispersed measurement, monitoring, and actuation devices. High-speed, fully integrated, two-way communication technologies make the grid dynamic and transactive for real-time information and power exchange will create a near plug and play environment. The deployment of smart devices and communication technologies enable the introduction of powerful data analytic capabilities, such as state estimation in distribution systems and unbalance monitoring. In this presentation, various aspects of the aforementioned will be discussed.
