DESCRIPTION:Jean Mahseredjian\, Professor École Polytechnique de Montréa
 l\, Ph. D.\, IEEE Fellow\nBio: Jean Mahseredjian graduated from École Pol
 ytechnique de Montréal with a Ph. D. in 1991. From 1987 to 2004 he worked
  at IREQ (Hydro-Québec) on research and development activities related to
  the simulation and analysis of electromagnetic transients. In December 20
 04 he joined the faculty of electrical engineering at École Polytechnique
  de Montréal. He is the creator and main developer of the EMTP-RV softwar
 e for the simulation of electromagnetic transients.\nAbstract: The complex
 ity of modern power grids requires using advanced computer based simulatio
 n methods for design\, operation and post-mortem analysis stages. Numerica
 l models and solution methods play dominant roles in technological advance
 ments in modern power systems. The needs for simulation capabilities incre
 ase significantly faster than the capability of researchers to deliver new
  simulation methods for solving increasingly complex problems.\nThis prese
 ntation is on the computation of power system transients using detailed ci
 rcuit level analysis methods. A unified and wideband vision is presented a
 nd includes unbalanced-multiphase load-flow solution\, initialization\, el
 ectromechanical transients and electromagnetic transients. The computation
  of electromagnetic transients (EMT) offers highest accuracy levels and al
 lows delivering wideband power system models.\nA multi-time frame vision i
 s proposed for combining various solution techniques into a single environ
 ment and for a single data set. Computational speed and accuracy must beco
 me adaptive according to grid regions and the frequency content of studied
  phenomenon.\nThe advent of multi-core processors\, with several CPUs acce
 ssing shared memory\, opens the path to significant innovations in the dev
 elopment of very efficient new algorithms for the computation of power sys
 tem transients. Parallel computing allows reinventing power system simulat
 ion methods and models. New numerical methods must be invented to harvest 
 the power of parallel computations and it is envisioned that such methods 
 can deliver advanced capabilities\, such as fully interactive numerical si
 mulators alike ancient analog simulators\, extension of the core of EMT-ty
 pe solution to the simulation of very large scale power systems and elimin
 ation of numerical gaps between off-line and real-time simulation tools.\n
 A key aspect in parallelization is the decoupling of network equations. Su
 ch equations are solved using sparse matrix techniques. Various formulatio
 n methods can be used to achieve network tearing. It is shown that diakopt
 ic analysis can be related to modified-augmented-nodal analysis which in i
 ts turn is related to hybrid analysis.\nThis talk also presents a new chai
 r project at École Polytechnique de Montréal on the multi time-frame sim
 ulation of transients for large scale power systems. The industrial partne
 rs of the chair project are Électricité de France\, Hydro-Quebec\, Opal-
 RT and RTE-France.
