2015 International Conference on Sustainable Energy Engineering and Application (ICSEEA), pp. Yatim, "Smart grid technology: Communications, power electronics and control system", Proc. Smart grid has several benefits such as integrated renewable energy, bidirectional power and data flow, data-driven pricing, and power consumption tracking among others [ 13 N.B.M. Because smart grid operates and depends on two-way communication flow, reliability and security of the communication methods are critical for proper information flow and management. Zhang, "Energy Big Data: A Survey,”", IEEE Access, vol. Smart grid is a modified traditional power system with six main components: network, user, hardware, software, servers, and data [ 2 H. Smart grid is as a complex electric grid system, which includes subsystems such as smart meters, power generations, substations, distribution, transmission, networking systems, etc. Lastly, the survey is concluded in section 6. The future of research in big data applications in smart grids is in section 5. Section 4 deals with big data challenges: security, quality, and processing location. Current research and studies of big data application in smart grids are reviewed in section 3. Definition of smart grid and energy big data is presented in Section 2. Such requirements highlight the importance of applying big data, whether it is machine learning, aggregation, or analytics, into smart grids. Xiang, "A secure cloud computing based framework for big data information management of smart grid", IEEE Transaction on Cloud Computing, vol. This is because the entire system can be interrupted by any delay [ 3 J. Another important requirement for smart grid is real-time information processing. As a result, the size of electric utility systems’ data reached Terabytes (TBs). For example, in the past, utility companies read meters monthly, but with the Advanced Meter Infrastructure (AMI), meters report data themselves every 15-30 minutes. Smart grid requires the capability for processing large volumes of real-time data. Sooriyabandara, "Smart grid communications: Overview of research challenges, solutions, and standardization activities", IEEE Comm. 11 th International Conference on Applied Computers and Computational Science, pp. Bakmaz, "Smart grid communications architecture: A survey and challenges", Proc. There are several roadblocks preventing smart grids from being used in larger regions such as information gathering, storing, processing, and management [ 7 Z. Farhangi, "The path of the smart grid", IEEE Power Energy Mag. Despite its numerous benefits, smart grid is mainly utilized in small regions [ 6 H. SG improves the efficiency, dependability, sustainability, and economics of electric services [ 6 H. Smart grids offer several benefits to electric consumers, producers, and operators. As an example, the ENEL Telegestore project in Italy is the first commercial project utilizing smart grid technology which brings annual savings of approximately 500 million Euros. Many countries have recently adopted smart grid renovation plans [ 3 J. Smart grid carries electricity and information between suppliers and consumers, which creates a bidirectional power and information flow system [ 2 H. It modifies the conventional power grid by integrating advanced communication and computing methods to improve the entire system control, efficiency, reliability, and safety ", IEEE Power Energy Mag. Smart Grid (SG) is an important research and development direction in the energy industry.
