Big Data Applications in Electric Energy Systems

Data-driven management of electric energy systems could provide major returns to system operation and control. This paper explores the potential applications of big data analytics in electricity grids. The primary sources of data in electric utilities are first outlined. These include phasor measurement units (PMUs), smart meters, intelligent electronic devices (IEDs), weather data, geographic information system (GIS), and electricity market data. Potential applications, relating to fault analysis, state estimation, security assessment, variable renewable energy, and power market operation are further described.
