Big data impact on stability and reliability improvement of smart grid

Smart grids systems generate a large amount of data. Big Data which is an essential element for improving the reliability, stability, and efficiency, and in decreasing the cost of energy use. Reliable operation of smart grid depends on the utilization of various real-time information related to monitoring, communications, control and management systems. This paper gives a common understanding of how big data can impact the reliability and stability of power grid, and investigates in detail a smart grid communication network architecture. In addition, the paper explores and collates the smart energy subsystem, the smart information subsystem, and the smart communication subsystem. This conceptual lens provides deep insights into the reliability challenges and effective solutions toward reliability issues in smart grid to reveal the big data role during the transition, and how it can fuel the organic growth of smart grid.
