Development of the multi-variable loss equation for a longitudinal power system

A method which divides a longitudinal transmission system into Northern, Central, and Southern regions of Taiwan is presented. A loss equation is developed to describe the system losses as a function of the three regional loads and the interchanged power flow among them. The coefficients of this multivariable equation can be determined by the use of a regression technique, and the losses calculated are more accurate than those derived from the single-variable equation for this particular system.<
