ABSTRACT
Power-flow studies are routinely used in planning, control, and operations of existing electric power systems as well as planning for future expansion. Satisfactory operation of power systems depends upon knowing the effects of adding interconnections, connecting new loads, introducing new generat ing stations, or constructing new transmission lines before they are installed. Power-flow studies also allow us to determine the best size and the most favorable locations for power capacitors both for improving the power factor and also raising the bus voltages of the electrical network. Powerflow studies help us to determine the best location as well as the optimal capacity of proposed generating stations, substations, or new lines.
