Abstract: This Paper presents study in terms of profit earned by generating units by increasing or decreasing their generation under ABT. The decision for increasing or decreasing the generation is taken after the comparison between Unscheduled Interchange (UI) rate and incremental marginal cost (IMC) of generators. For this study ABT Based Load Frequency Controller for an isolated area having four generator power systems is used. All the generators are scheduled to generate less than their capacities. So that it can increase their generation in case of increase in sudden load demand. Frequency signal is converted into price by using Matlab function in accordance with the UI rates issued by Central Electricity Regulation Commission (CERC, INDIA) in year 2014. This controller ensures that generators respond to the UI price automatically and in a desirable manner. All the generator models are simulated in Matlab Simulink. The paper is organized as follows. In section I brief introduction is given. In Section II we explain concept of ABT. Section III comprises of details of ABT based load frequency controller. Details of simulation model and results are discussed in section IV. This is followed by conclusions in Section V.
