works on advanced simulation methods for large
scale and complex power systems
> Advanced real-time simulation methods
> Advance off-line simulation methods
> Sophisticated utilization of simulation tools for
transmission and distribution network studies
> Integration of wind generation: 4 GW by 2015
•
Based on detailed studies of electromagnetic and
electromechanical transients
> At Hydro-Québec (TransÉnergie) the frequency
range of simulation models has been constantly
increasing with increasing computer speed,
improved models and numerical performance.

Real-Time simulator
> Capability to solve power systems quickly enough to
produce outputs synchronized with the real-time clock

A second of simulation = 1 second of clock time when testing equipment
> A real-time simulator can be connected directly to power system
control and protection equipment to test the equipment under
realistic conditions
•
•
For detecting abnormal operating conditions that cannot be found through
numerical models
For super-fast contingency analysis
> Hydro-Québec develops HYPERSIM: a real-time simulator

Develop, improve and assess new protection and control
concepts

Optimize the operation and the maintenance power systems

Decrease the time required to commission protection relays and
control systems (FACTS, HVDC, SVC, etc..)

Reproduce events that occurred in the power system by using the
actual protection and control systems

New Trends: Parallel computing
> Availability of increasing calculation capabilities
through multicore computers
> Power system simulations involve the solution of linear
sparse systems
> Traditional methods are generally sequential and use
only one CPU
> The matrices are very sparse, moderate size, coupled
and unsymmetrical
> For Load flow and steady-state studies the matrices are
coupled but the solution is performed once
> For time domain it is possible to use the natural delay of
the lines to decouple the system. Not always feasible!
> It is essential to explore new ways to increase the
speed of calculations while maintaining accuracy
> Hydro-Québec with Ecole Polytechnique of Montreal and
RTE (France) are collaborating in an important research
project to increase the speed of calculations using the
possibilities offered by new technologies

New Trends: Collaborative computing,
Co-simulation
> Parallel computing can be done in a
collaborative approach
> Several simulation tools addressing different
aspects, telecom, control, electromechanical
and electromagnetic transients, collaborate
together to simulate the same power system
> Collaborative software environment can be
implemented through a co-simulation channel
in an indirect interaction (FMI)
> Use Federated simulation systems run-time
infrastructure (RTI) to support
interoperability (HLA)
> Scalable performance via parallel and
distributed simulation techniques
