Generalized three phase coupling method for distributed simulation

Simulation of power system behavior is a highly useful for planning, analysis of stability and for operator training. Traditionally, small power system studies are dominated by time taken to solve the machine dynamics equations while larger studies are dominated by the time taken to solve the network equations. With the trend towards more sophisticated and realistic modeling, the size and complexity of simulations of a power system grows tremendously. The ever-increasing need for computational power can be satisfied by the application of distributed simulation. In this paper, distributed simulation indicates separately and concurrently computing subsystem´s solution of a large-scale power system. History distributed simulation techniques are briefly introduced. A generalized three-phase coupling method for distributed simulation is proposed. The algorithm is tested with simple case and the test results are presented and analyzed.
