Parallel processing in power systems computation

The current status of parallel processing as used in electric power systems analysis is presented. The use of parallel processing is induced by the need for rapid solution in power system problems. For a specific problem, a separate derivation has to be made that could be used as a parallel algorithm. The answer has to done in a parallel machine with compatible architecture and algorithms. The last decade has seen research done on algorithm development and the evaluation of multiprocessor architectures has just began. Hardware development still has no definite path with existing machines suitable only for research work.
