Dr. Sorin Olaru

Dr. Sorin Olaru of CentraleSupelec, France

Topic:

Set-theoretic methods for fault detection and isolation in feedback control schemes

The development of set-theoretic methods and the associated theoretical concepts found applications in various domains, such as robust control, predictive control and fault diagnosis. The aim of this talk is to present novel trends in fault diagnosis and fault-tolerant control based on such set-theoretic methods.


The basic idea will be to use the strong concept of positive invariance for the characterization of dynamical systems affected by uncertainty. The positive invariance of sets characterizing the nominal and the abnormal dynamic behaviour will be shown to present a particular interest for the diagnosis of the control systems (with particular exemplification of multi-sensor systems) via set separation. From a broader theoretical perspective, we point to the link between the diagnosis and the control law design. It is shown that the Fault Tolerant Control can be enhanced by a reference governor or a predictive control scheme which adapts the state trajectory and the feedback control action in view of active fault detection.

Topic:

Renewable Energy Source Integration by Multi Terminal High Voltage Direct Current (MT-HVDC) Networks

New technologies in control, computers and communications have allowed the possibility of a future power grid quite different from the present one. These so called Smart - Grids have, as one of their main goals to better facilitate the connection and operation of renewable energy sources (renewables) to significantly reduce the environmental impact of the whole electricity supply system; as well as to deliver enhanced levels of reliability and security of supply.


During the last few years, global warming and pollution has pushed governments to reduce the impact of human activities. One of the main challenges Smart-Grids will have to cope with is a direct consequence of the European Union 20-20-20 Energy policy: by the year 2020 - to cut 20% of CO2 emissions; to make 20% energy savings; and to use 20% of energy production from renewable sources. This is a very important problem, because these sources are, in general, time varying in a fast and, to some extent, unpredictable manner: wind force variation, cloud cover and sunshine ... These characteristics of renewables make the development of new techniques necessary so as to better integrate them into the power grid.


One of the possibilities for dealing with this problem is to use High Voltage Direct Current connections. This very challenging topic is at the center of many international projects like Winpower, Twenties, SuperGrid and Bestpath. But most HVDC links are bi-terminal (one sending and one receiving). Moving forward in this way will economically and technically lead to an unsustainable  scheme, therefore leading toward Multi-Terminal HVDC networks.


However, the scientific and technical literature has not yet solved voltage and power quality control on multi-terminal DC networks. Solving such problems requires a complete re-thinking of a new system, in particular at the control level. Classical control schemes are not able to cope with the large variability and complexity of such systems. It is then necessary to develop a wide -ranging control strategy to manage large scale MT-HVDC networks that will interconnect renewables to the main power network. This new strategy needs to deal with large scale networked power system issues like delayed remote information, uncertainties, interconnected nonlinear dynamics and mixed time scales.


It is then necessary to use a multi-layered strategy coming from slow scale top layers dealing with weather forecasts and real-time energy markets, through discrete time predictive layers dealing with physical constraints, to finally arrive at the fast real-time non-linear control of the converters that constitute the terminals.

Gilney Damm is Associate Professor at the Evry-Val d'Essonne University, and the Laboratoire des Signaux et Systèmes, France. He received his Habilitation à Diriger des Recherches in 2010; his Ph.D. Thesis at the L2S CNRS/Supelec/Université Paris Sud in 2001 on the “Contributions on the stabilization of power generators”; his M.Sc. at COPPE-Rio de Janeiro Federal University (UFRJ) in 1997 and his Bachelor in Electronic Engineer at the Rio de Janeiro Federal University in February 1995. His research interests concern nonlinear and adaptive control and observers applied to power systems (SmartGrids). His main applications are in the field of large scale renewable energy integration; Multi-Terminal HVDC systems; Variable Speed Pumped Storage Plants; control of power generators (transient stabilization, frequency and  voltage stability); synchronization of power networks; solar panels' control.

He has a large experience as coordinator or Work-Package Leader in several European and French research projects as the European Network of Excellence on Highly Complex and Networked Control Systems - HYCON2, the Smart Energy Summer School supported by the Knowledge and Innovation Community (KIC) ICT LABS from the European Institute of Innovation and Technology, or the project WINPOWER about the integration of wind and solar based electrical power by a High Voltage Direct Current (HVDC) multipoint network. In the same way, he is co-leader of the french research forum on SmartGrids, he is co-leader of the Research Initiative Large Scale Systems and SmartGrids from the Institute for Control and Decision of Paris Saclay – iCODE, and he was scientific responsible for the control of power networks in the SuperGrid institute, where he still keep a strong activity.

He has received the French research excellence grant (Prime d'Excellence Scientifique) since 2008, and is member of the IFAC Technical Committee TC 6.3 Power and Energy Systems.
