APPLICATION OF COMPUTER SOFTWARE IN TRANSMISSION EXPANSION PLANNING USING VARIABLE LOAD STRUCTURE

The present paper proposes a computer-rated transmission expansion pla nning approach using the network simplex technique. A six-bus sample s ystem is used for illustration. Assuming an increased load demand, an optimum network configuration is designed. Software is developed to ob tain the optimum network configuration, which uses variable load struc ture and generator cost curves for economic generation. Curves are pre sented of the diversity factor versus mileage and number of circuits, assuming ten different load curves.
