This paper discusses performance improvements achieved in fast-decoupled load flow solution through the use of parallel processing techniques. The fast- decoupled load flow formulation consists of two decoupled system models that can be solved simultaneously using two- core processors. The IEEE 30, 57, 118, 300 and 664 bus are used to evaluate the proposed program performance using parallel processing based on multi-core processors computer. The result shows that the parallel processing produces speedup for all cases. The performance and speedup of load flow solution by using two processors is near twice for all parallel part of the test systems. The result have followed the Amdal’s law speedup equation.
