Title: Dynamic Modelling and Advanced Control Design In Renewable Energy systems

Abstract:

The large increase in the penetration of renewable energy systems to the power network during the last decades has had a direct impact in the stability and reliability of the grid. Since power electronic converters are essential for the integration of renewables to the electric grid, the performance of the grid-connected units and consequently of the network mainly depends on the control design. To this end, accurate dynamic modelling of power converter-fed units is required. This talk will first focus on the modelling of some typical power converters and a complete grid-connected wind power system will be thoroughly investigated. Control design methods will be analysed including traditional and advanced control schemes, and some recently developed bounded controllers will be presented, which are completely parameter-free and guarantee non-linear closed-loop system stability. Finally, existing challenges in micro-grids and larger power networks will be provided and the need for accurate dynamic modelling and advanced control design will be underlined.

Short Bio:

George Konstantopoulos received his first-class Diploma and PhD in Electrical and Computer Engineering from the Department of Electrical and Computer Engineering of the University of Patras, Greece, in 2008 and 2012, respectively. From January 2011 to July 2012, he has worked as an Electrical Engineer at the Public Power Corporation of Greece in the area of renewable energy systems integration to the medium voltage grid. From May 2013, he has been with the Department of Automatic Control and Systems Engineering of the University of Sheffield, UK, initially as a Postdoctoral Researcher and now as a Lecturer. His main research interests include non-linear modelling, control and stability analysis of power converter and electric machine systems with emphasis in micro-grid and smart grid systems, renewable energy systems and motor drives. Dr. Konstantopoulos is a member of the IEEE and a member of the National Technical Chamber of Greece.
