Big data metadata management in smart grids

Abstract

Smart home, smart grids, smart museum, smart cities, etc. are making the vision for living in smart environments come true. These smart environments are built based upon the Internet of Things paradigm wheremany devices and applications are involved. In these environments, data are collected from various sources in diverse formats. The data are then processed by different intelligent systemswith the purpose of providing efficient system planning, power delivery, and customer operations. Even though there are known technologies for most of these smart environments, putting them together to make intelligent and context-aware systems is not an easy task. The reason is that there are semantic inconsistencies between applications and systems. These inconsistencies can be solved by using metadata. This chapter presents management of big data metadata in smart grids. Three important issues in managing and solutions to overcome them are discussed. As a part of future grids, some concrete examples from the offshore wind energy are used to demonstrate the solutions.
