Economic Analysis of a Deregulated Power System Using the Proportional Tracing Method

Continuing trend towards deregulation and unbundling of transmission
services has resulted in the need to measure the flow of power primarily for
pricing and tariff purposes. Tracing methodology hence had been introduced to
overcome problems related to the Marginal pricing of transmission costs. This
study is twofold: the first revolves around the validation of the method and a 360°
analysis of the proportional method which leads to a redefined power tracing
method; the second is to further refine the proposed prediction method in [1] by
establishing trends of the learning coefficients, using them to examine the
relationship between accuracy and number of samples taken. Response of
individual generators to change in demand and the corresponding associated
losses are also presented. MATLAB with matpower4.0b extension was used to
present the stody on the IEEE 24bus RTS. Finally a real time amenable prediction
tool using the regression method will be proposed.
