Reliability data for smart grids: Where the real data can be found

Smart Grids play an important role in modern society and for the sustainability of its wellbeing. However, the undoubted advantages come at the cost of higher complexity, especially at the level of information and communication technologies that enhance the physical grid infrastructure. As such, software quality requirements, such as reliability, resilience, safety, security, privacy, and performance assume a more functional facet. In this paper, we focus on software reliability as one of the key qualities of a Smart Grid infrastructure, which is however not yet well defined and understood. We formulate relevant definitions of software reliability in the Smart Grid context, categorize information necessary to quantify the identified reliability views, and explore existing literature and online resources to assess what datasets, necessary for reliability quantification, are available to make the reliability assessment possible.
