Abstract :
This paper discusses and compares the use of parallel computers and distributed networks of computers as a means of solving the contingency analysis problem in an energy management system environment. The paper reports results obtained with a difficult real-life system (the South-Southeastern Brazilian interconnected network with 810 buses). Performance indices such as speedups and processor efficiencies are discussed in the paper. The numerical results illustrate the relative performances of the two computing environments as well as the concurrent programming model implemented in each environment
