Hybrid Scheme of Electricity Metering in Smart Grid

The hybrid scheme of electricity metering combining time- and event-driven approaches makes visible events. It enables the detection, understanding, and management of nonstationary flows of electricity as they vary by real-life processes. We use the internal metering data to supply electric values and additional meta-information being elicited, e.g., scalar values characterizing variations of power flows and their timing. The capability to recognize events and their sequences produces new information flows in smart grids. We discuss how to exploit the process knowledge in the grid's control.
