With the growth of the interconnected power system in size and complexity, the dynamic stability simulation in time domain is becoming increasingly time-consuming. In order to speed up dynamic analysis to meet the needs for real-time simulation, a parallel computing method for three most time-consuming subroutines in dynamic simulation program is developed, where the network equation is solved in parallel by using the Jacobian iteration method by which load equalization among sub-processors is realized. This method is capable of utilizing the conventional source code of dynamic simulation that makes the program more reliable and compatible. The results of an actual case show that the parallel method proposed can accelerate the dynamic analysis up to a faster-than-real-time computation level for a power system.
