Abstract:
The secure and optimal operation of power transmission systems does require the knowledge of the system state (i.e., the state estimation – SE) since it is used by several critical functions such as: security assessment, voltage control and stability analysis. Traditionally, the SE has been performed at relatively low refresh rates (i.e., several minutes) in view of the technological limits of the so-called remote terminal units (RTUs). Nowadays, the emerging availability of phasor measurement units (PMUs) allows to acquire accurate and time-aligned phasors, called synchrophasors, with streaming rates in the order of several tens of measurements per second that are used to infer the system state in a time-deterministic way. This technology is experiencing a fast evolution and being associated to a number of applications. PMUs already compose the backbone of wide area monitoring systems of power transmission networks. However, this technology may be central even in the context of power distribution networks to optimally exploit these systems to maximize their hosting capacity of stochastic resources (i.e., photovoltaic and wind power generation, distributed energy storage systems, electrical vehicles). Within this context, the seminar illustrates the methodological aspects associated to recent developments in PMU-based time-deterministic situational awareness systems for the monitoring, control and protection of future power networks.

Prof. Mario Paolone received the M.Sc. (Hons.) and Ph.D. degrees in electrical engineering from the University of Bologna, Italy, in 1998 and 2002. In 2005, he was an Assistant Professor in power systems with the University of Bologna, where he was with the Power Systems Laboratory until 2011. Since 2011, he has been with the Swiss Federal Institute of Technology, Lausanne, Switzerland, where he is currently a Full Professor and the Chair of the Distributed Electrical Systems Laboratory. His research interests focus on power systems with particular reference to real-time monitoring and operational aspects, power system protections, dynamics and transients. Prof. Paolone has authored or co-authored over 300 papers published in mainstream journals and international conferences in the area of energy and power systems that received numerous awards including the IEEE EMC Technical Achievement Award, two IEEE Transactions on EMC best paper awards, the IEEE Power System Dynamic Performance Committee’s prize paper award and the Basil Papadias best paper award at the 2013 IEEE PowerTech. Prof. Paolone was the founder Editor-in-Chief of the Elsevier journal Sustainable Energy, Grids and Networks.
