Assessing impact of ICT system quality on operation of active distribution grids

This position paper presents starting research on assessment of ICT system characteristics and their impact on controllability and observability of future electricity distribution grids. The aspects of controllability and observability for active grids are key factors for guaranteeing safe, efficient and reliable network operation. An assessment framework is proposed for analyzing the impact of ICT system quality on controllability and observability of the power distribution grid. The proposed assessment method is based on architectural models extended with a probabilistic inference analysis engine. For this, a combination between Enterprise Architecture meta-models and extended influence diagrams are proposed. The paper presents how the framework is constructed and the method on applying it for analysis. The paper is concluded with an example providing an instantiation of the assessment framework.
