Developing concurrent processing applications to power system planning and operations

The authors describe the implementation of existing power system applications in a concurrent programming environment. The tools used comprise a multiprocessor computing system with concurrent processing software facilities and a concurrent processing simulator for assisting in problem partition and debugging. The goal is to obtain shorter execution times taking into account the solution structure. Three case studies are used to illustrate the application of the above tools and the development methodology: multiarea reliability, system analysis model, and security-constrained dispatch with postcontingency corrective rescheduling. Results obtained show a very high efficiency in the use of the concurrent processors.<>
