The power system is gradually evolving towards a distributed infrastructure with thousands of controllable end-points. Transformative changes are particularly pronounced at the distribution level, where growing numbers of renewable sources, energy storage devices, and flexible loads are being installed with power-electronics converters serving as the energy conversion interface. The talk focuses on the synthesis of distributed controllers that leverage the opportunities for fast feedback offered by power-electronics-interfaced renewable energy resources (RESs). The overarching objective is to bridge the temporal gap between long-term system optimization and real-time control, to enable seamless RES integration in large scale with stability and efficiency guarantees, while congruently pursuing system-level optimization objectives. The proposed controllers enable an update of the power outputs at a time scale that is compatible with the underlying dynamics of loads and ambient conditions, and continuously drive the system operation towards OPF-based targets. Convergence and OPF-solution-tracking capabilities are established while acknowledging: i) communication-packet losses, and ii) partial updates of control signals. The latter case is particularly relevant since it enables asynchronous operation of the controllers where DER setpoints are updated at a fast time scale based on local voltage measurements, and information on the network state is utilized if and when available, based on communication constraints.


Emiliano Dall'Anese received the Laurea Triennale (B.Sc Degree) and the Laurea Specialistica (M.Sc Degree) in Telecommunications Engineering from the University of Padova, Italy, in 2005 and 2007, respectively, and the Ph.D. in Information Engineering from the Department of In- formation Engineering, University of Padova, Italy, in 2011. From January 2009 to September 2010, he was a visiting scholar at the Department of Electrical and Computer Engineering, University of Minnesota, USA. From January 2011 to November 2014 he was a Postdoctoral Associate at the Department of Electrical and Computer Engineering and Digital Technology Center of the University of Minnesota, USA. Since December 2014 he has been a Senior Engineer at the National Renewable Energy Laboratory, Golden, CO, USA. His research interests lie in the areas of optimization, signal processing, power systems, and communications. Current efforts focus on distributed optimization and control of power distribution systems with distributed (renewable) energy resources.
