Distributed Power System Simulation on a Hypercube Computer

Abstract Distributed system is expected to realize characteristics of flexibility, high modularity, easy development, high speed processing and cost performance in the system of several fields. The use of distributed systems on parallel or distributed computers are studied for getting these characteristics. We developed a distributed simulation method of power systems to get high modularity such as easy attaching and detaching new components of power systems in the simulator for extension or maintenance. In this paper, we describe the detail of the distribution methods of power system simulation. First, we propose the distributed algorithm of solving network equations of power system simulation. Secondly, we describe the way to mapping tasks to be separated for distributed simulation to a hypercube computer. Thirdly, we show the flow of simulation including communication method with time stamp technique. Our approach is installed and evaluated in the hypercube computer, NCube/10. In the hypercube computer, each bus and each control circuit of generator in a power system are assigned to each processor. Finally, we show the result of installing and evaluating them.
