This paper describes the implementation of a Monte Carlo based short-circuit analysis package in a hypercube parallel computer . The program generates accurate estimates of short-circuit current probability distribution curves which can be used in a variety of planning and design studies. Both network modeling aspects, such as network reduced equivalencing and mutual coupling representation, as well as the impact of the sample sizes used in Monte Carlo simulations are fully analyzed and illustrated by numerical results obtained testing on real-world systems. These examples clearly illustrate how computational efficiency in parallel machines varies with the ratio of communication to computation (communication overhead) and of the load balancing among the parallel computer processors.

No dia cinco de agosto passado fez um ano que Alcir Monticelli nos deixou. Seu legado está certamente presente nas aplicações de sistemas de potência, em que era especialista. Nas últimas décadas, têm-se observado avanços significativos na área de sistemas de potência e Alcir Monticelli tomou parte importante nesse processo de transformação, com sua impressionante capacidade de interagir com a área acadêmica como professor e também como pesquisador que busca soluções práticas para os problemas mais desafiadores na área de sistemas de potência. Neste texto, feito a convite da Revista Controle & Automação (SBA), que manifestou o desejo de homenageá-lo, procuraremos relembrar algumas de suas maiores contribuições para a área de sistemas de potência, bem como registrar o reconhecimento mundial de seu trabalho.
On August 5th, one year passed since Alcir Monticelli left us. His legacy is very present in power system applications, which was his speciality. Significant improvements in power systems have undergone in the last decades and Alcir Monticelli has importantly taken part of the transformation process with his amazing capacity to interact with the academic area as a professor and also as a researcher working toward practical solutions to the most challenging problems in power systems. In this article, which is an invitation from Revista Controle & Automação (SBA) to honor the Alcir's memory, we will remember some of his major contributions to the power systems area and also register the recognition of his work worldwide
