DESCRIPTION:Prof. Claudio De Persis\, Faculty of Science and Engineering\,
  University of Groningen\nAbstract: With the proliferation of renewable so
 urces and the interest in preventing inefficient power conversions\, there
  is an increasing attention towards DC microgrids. Similarly to AC microgr
 ids\, two key requirements on DC microgrids performance are a fair sharing
  of the loads among the power sources and adequate voltage levels.  \nIn 
 this talk\, I describe the so-called power consensus algorithm for a resis
 tive DC network in the presence of constant impedance\, constant current a
 nd constant power loads. The proposed algorithm features a communication n
 etwork over which the source nodes exchange information about the instanta
 neous powers\, and which is used to adjust the injected currents according
 ly. This gives rise to a nonlinear consensus-like system of differential-a
 lgebraic equations that is analyzed via Lyapunov functions inspired by the
  physics of the system. The analysis shows convergence to the set of equil
 ibria\, where weighted power consensus is achieved\, as well as preservati
 on of the weighted geometric mean of the source voltages. \n\nBio: Claudi

 aculty of Science and Engineering\, University of Groningen\, the Netherla
 nds and affiliated with the Jan Willems Center for Systems and Control at 
 the same university. He received the Laurea degree in Electronic Engineeri
 ng in 1996 and the Ph.D. degree in System Engineering in 2000 both from th
 e University of Rome ‘‘La Sapienza’’\, Italy.\nPreviously he held 
 faculty positions at the Department of Mechanical Automation and Mechatron
 ics\, University of Twente and the Department of Computer\, Control\, and 
 Management Engineering\, University of Rome ‘‘La Sapienza’’. He wa
 s a Research Associate at the Department of Systems Science and Mathematic
 s\, Washington University\, St. Louis\, MO\, USA\, in 2000–2001\, and at
  the Department of Electrical Engineering\, Yale University\, New Haven\, 
 CT\, USA\, in 2001–2002.\nHis main research interest is in control theor
 y\, and his current research focuses on dynamical networks\, cyber-physica
 l systems\, smart grids and resilient control. He was an Editor of the Int
 ernational Journal of Robust and Nonlinear Control (2006-2013)\, an Associ
 ate Editor of the IEEE Transactions on Control Systems Technology (2010-20
 15)\, and of the IEEE Transactions on Automatic Control (2012-2015). He is
  currently an Associate Editor of Automatica (2013-present) and of IEEE Co
 ntrol Systems Letters (2017-present).
