DESCRIPTION:Johannes Schiffer\, University of Leeds\, UK\nAbstract: Freque
 ncy control is one of the most relevant control applications in power syst
 ems. Traditionally\, this task has been carried out on the high-voltage tr
 ansmission system by using large fossil-fueled power plants as actuators. 
 Yet\, the increasing penetration of distributed renewable generation inter
 faced to the network via power inverters renders these conventional scheme
 s inaproppriate\, creating a clear need for robust and distributed solutio
 ns that actively integrate generation units on the lower voltage levels. T
 hus far\, the literature on distributed frequency control has primarily fo
 cused on disturbance rejection\, steady-state optimality and adaption to c
 omplex physical system models without considering uncertainties on the cyb
 er and communication layer nor their effect on robustness and performance.
  In the present talk\, sufficient delay-dependent conditions for robust st
 ability with respect to heterogeneous delays\, link failures and packet lo
 sses will be provided via the Lyapunov-Krasovskii method. The efficacy of 
 the proposed conditions is illustrated by numerical examples.\n\nBio: Joha
 nnes Schiffer received his Diploma degree in Engineering Cybernetics from 
 the University of Stuttgart\, Germany\, in 2009 and a Ph.D. degree (Dr.-In
 g.) in Electrical Engineering from TU Berlin\, Germany\, in 2015. Currentl
 y\, he is a Lecturer (Assistant Professor) at the School of Electronic & E
 lectrical Engineering\, University of Leeds\, UK. Prior to that\, he has h
 eld appointments as research associate in the Control Systems Group (2011 
 - 2015) and at the Chair of Sustainable Electric Networks and Sources of E
 nergy (2009 - 2011) both at TU Berlin. His current research interests incl
 ude distributed control and analysis of complex networks with application 
 to microgrids and power systems.
