Abstract:

 The electric power grids across Europa are evolving towards decentralized structures, rooted in political decisions to counter the worldwide climate change. Especially the German power grid is facing the disruptive challenge to integrate massive decentral infeed of renewable electric power. This implies drastically higher volatility in available electric power, which in turn is a threat to power grid stability across the entirety of continental Europe.

This presentation discusses the challenge as a large-scale distributed control problem. We derive a set of principles that inspire the design of a new generation of distributed and decentralised power grid control appliances. We report on controller designs for masses of microgenerators, and contrast their reliable operation with critical shortcomings of controllers installed on hundreds of thousands of German rooftops to date. While doing so, we discuss a modelling and verification technology revolving around stochastic hybrid automata, employed to validate and evaluate these controllers.

Holger Hermanns is a full professor in the Department of Computer Science at Saarland University, Saarbrücken, Germany, holding the chair for Dependable Systems and Software. His research interests include modeling and verification of concurrent systems, resource-aware embedded systems, and compositional performance and dependability evaluation, including dependable energy distribution grids. In these areas, Holger Hermanns has authored or co-authored more than 150 peer-reviewed scientific papers, has co-chaired the program committees of major international conferences such as TACAS 2006, CONCUR 2006, CAV 2007, and QEST 2012. He serves on the steering committees of ETAPS, TACAS and QEST, and has authored a monograph in the LNCS series of Springer-Verlag on interactive Markov chains. He received the Dutch national innovation award, is a founding member and principal investigator of the German special research initiative SFB AVACS, coordinator of the EU FP7 project MEALS, and holder of several other national and European research grants.
