Scheduling data access in Smart Grid networks utilizing context information

摘要

Current electrical grid is facing increased penetration of intermittent energy resources, in particular wind and solar energy. Fast variability of the power supply due to renewable energy resources can be balanced out using different energy storage systems or shifting the loads. Efficiently managing this fast flexibility requires two-way data exchange between a controller and sensors/meters via communication networks. In this paper we investigated scheduling of data collection utilizing meta-data from sensors that are describing dynamics of information. We show the applicability of this approach for a constraint communication networks of the smart grid and compared three general data access mechanisms, namely, push, pull and event-based.
