Parallel implementation of power system dynamic simulation

Dynamic simulation of power system transient stability is important for planning, monitoring, operation, and control of electric power systems. However, modeling the system dynamics and network involves the computationally intensive time-domain solution of numerous differential and algebraic equations. This results in a transient stability simulation implementation that does not satisfy the real-time constraints of online dynamic security assessment. This paper presents a parallel implementation of the dynamic simulation on a high-performance computing platform using parallel simulation algorithms and architectures. It enables the simulation to run even faster than real time, enabling the “look-ahead” capability to study pending stability problems in the power grid.
