View-based and Model-driven Outage Management for the Smart Grid

چکیده
The integration of renewable energy resources is challenging the traditional electricity network. To manage this, the smart grid has been defined as a cyber-physical system consisting of a physical component, which is the electricity grid, and a computational component consisting of a communication network, metering network, and software components. Therefore, the smart grid can not just be seen as an electrical grid, but also as a system of software systems. Currently, control centers of the smart grid use an outage management software system to react to reported outages. In this paper, we present an extended outage management system that solves one main problem of the smart grid: software systems of the different domains are using different standards. Consequently, cross-domain data exchange and analysis are difficult. Therefore, we use the model-driven view-based VITRUVIUS approach to build a unified model of the smart grid. We then combine it with system stability analysis methods presented as views on the model. The result is a model-driven run-time monitoring, analysis and control framework to increase the reliability of power supply. The evaluation with statistical data of the German power grid shows that outage time can be reduced with our approach.

Association rule mining application to diagnose smart power distribution system outage root cause
Smart grid has been introduced to address power distribution system challenges. In conventional power distribution systems, when a power outage happens, the maintenance team tries to find the outage cause and mitigate it. After this, some information is documented in a dataset called the outage dataset. If the team can estimate the outage cause before searching for it, the restoration time will...

To cope with the increased complexity, physical systems are more and more supported by software systems consisting of multiple subsystems. Usually, each of the subsystems uses standards relevant to the subsystem for interoperability with other tools. Thus, one faces the problem that information about the system as a whole is distributed across multiple models. To solve this problem, model views...
