Topic: Pan European Grid Advanced Simulation and State Estimation (PEGASE)
Abstract: PEGASE is a four year project dealing with the High and Extra High Voltage transmission and sub-transmission networks in Europe and is implemented by a Consortium composed of 20 Partners including TSOs, expert companies and leading research centers in power system analysis and applied mathematics. Developing smart grid tools at transmission level is the overall objective of the project by defining the most appropriate state estimation, optimization and simulation frameworks, their performance and dataflow requirements to achieve an integrated security analysis and control of the European Transmission Network (ETN). The heart of the PEGASE project involves advanced algorithmic, building prototypes of software and demonstration of the feasibility of the proposed solutions on very large model representative of the ETN and taking into account its operation by multiple TSOs.
This panel will first address the global challenges of the PEGASE project to develop smart transmission grid algorithms (1). Next, R&D work to be able to provide all TSOs with a synchronous display of the state of the European Transmission Network very close to real time will be presented (2). The development of Optimal Power Flow programs determining realistic system operating points that include TSO operating rules, typically for real-time congestion management, will then be presented, including a worst case approach (3 and 4). Finally, improvement of the existing state of the art technology in time simulation of very large systems will be addressed to be able to offer (5) off-line studies of the ETN including possibly interconnections with neighboring system (i.e. Mediterranean Ring, Russia) and (6) on-line preventive security assessment or faster than real-time simulation in emergency conditions.

Biography:Brian Stott is a Member of the US National Academy of Engineering. In the IEEE he is a Fellow, a recipient of the Millennium Medal and a Distinguished Lecturer.
He has worked all his life on the application of computer methods to the secure economic operation of electric power grids and their modern markets.
In 1984 he co-founded Power Computer Applications Corporation in Arizona, to develop network analysis and optimization software for online and market applications. In 2000, the company was acquired by Nexant Inc., to whom he remains an independent consultant. This software has been installed in over 100 energy management centers worldwide, and is used by the Independent System Operator (ISO) markets in North America.
He previously worked in England, Turkey, Canada and Brazil. He has given lectures and courses in many countries. He has served as advisor and consultant on many projects in North and South America and in Europe.
