Abstract
ABT stands for techno commercial tool for bringing rational tariff structure for supply of electricity from generating station to beneficiaries on a contracted basis. It is a system for the scheduling and dispatch of power, with rewards and penalties as per the day ahead schedule for both generators and beneficiaries. ABT helps to improve the power quality and curtails the following: 1. Rapid and high frequency deviations. 2. Frequent grid disturbances results in generator tripping, power outages and grid instability. ABT mainly includes: 1. Power scheduling and dispatch which includes current day and day ahead scheduling. 2. Tariff structure which includes fixed charges, variable charges and the deviation charges. The proposed MATLAB software based frequency control model is used for automatic frequency control of generator using the prevailing deviation price for the deviation from the schedule.
