Load Flow Simulation of Western Grid of Bangladesh Power System Using PSAT and Performance-Based Comparison with PowerWorld

This paper describes the load flow simulation studies of the Western grid of Bangladesh Power System using PSAT, a free and open-source software and compares the results with those from PowerWorld, a well-accepted and commercial software. The studied power system contains 41 buses and 82 interconnecting lines. To ground the basis of comparison, both of the applications were run in the same simulation environment with identical input data. For this system, an average difference of 1.7525% between the bus voltage magnitudes calculated by the two software packages was found and PowerWorld was 6.4 times faster than PSAT to complete the simulation.
