Abstract :
[en] Hydro-Québec has a long interest in on-line Dynamic Security Assessment (DSA) driven by its challenging power network dynamics (angle, frequency and voltage stability, short and long-term dynamics). At the moment, off-line calculated security indicators are combined with an on-line monitoring system to ensure the security of the system. However, new developments in power system dynamic simulation algorithms facilitate real-time or near-real-time DSA calculations and enable on-line transfer limits determination. In this paper, the domain-decomposition-based algorithm implemented in the dynamic simulator RAMSES is presented, along with the techniques used to accelerate both its sequential and parallel execution. RAMSES exploits the localized response of power systems to disturbances and the timescale decomposition of dynamic phenomena to provide sequential acceleration when the simulation is performed on a single processing unit. In addition, when more computational units are available, the parallelization potential of domain-decomposition methods is exploited to provide parallel acceleration. The presented algorithm and techniques are tested on a realistic model of the Hydro-Québec system and the accuracy of dynamic response, the sequential and parallel performances are evaluated. Finally, the real-time capabilities of the simulator are assessed using a shared-memory parallel processing platform.
