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