AbstractThis paper discussed about load flow simulation from interconnection two systems at annual peak load used EDSA (Electrical Power System Design Software) . Simulation method using Newton-Raphson (NR) method it’s excellent at accurate, criteria, speed reach for convergent than other method. Load flow analyze purpose is to knowing value of voltage vector at each node and the value of load flow at each branch from a network for curtain condition in normal condition. Load flow analyze playing important role in planning and development electric power in the future because optimal operating depends on the knowledge of influence from interconnection to other system, influence of adding new load, new generating station and new transmission line. Using simulation have done know condition system at annual peak load its close bad, where capacity power generating didn’t enough for serve consumer, drop voltage in some area have come near permitted rule constrain.
