A framework for the integration of ICT-relevant data in power system applications

This paper proposes a framework for using information communication technology (ICT) monitoring information to provide another dimension to the reliability assessment of physical measurement data used in power system decision making. ICT monitoring information covers the health of (1) operational technologies through monitoring of resources such as CPU, memory or network interfaces and (2) communication channels by monitoring the network traffic. This information may be used as an additional trust index to measurements that feed into SCADA applications such as voltage stability assessment, state estimation and contingency analysis in terms of decision making. This is especially important in case of failures, malfunctions, and attacks affecting the system robustness and safety. This paper demonstrates the added value of ICT health information to state estimation. The proposed framework is integrated with a real-time co-simulation platform for multi-domain testing and evaluation of additional applications.
