Objectives: To simulate automatic generation control (AGC) operation in a deregulated power system under availability based tariff (ABT) mechanism to regulate grid frequency during peak and off-peak hours. Method: For the simulation, the two areas, an isolated power system with Area1, which has thermal - hydropower plants with two DISCOs, and Area2 having a thermal – thermal power plant with two DISCOs have been considered. DISCO participation matrix (DPM) has been used for the visualization of bilateral contract by distribution companies (DISCOs) in the restructured environment. An AGC operation of two area power system with 10% load variations during peak hour and off-peak hour has been presented for the 24 hours in graphical form. Findings: The deviations in the grid frequency and Unscheduled Interchange (UI) charges or deviation settlement mechanism (DSM) rates of ABT due to sudden load changes and renewable power found. The frequent AGC operation of generators against load variation to stabilize the grid frequency is increasing wear and tear losses which finally increases maintenance cost and sometimes tripping of generators. Also, in peak hours and off-peak hours the drastic change in UI charges found during AGC operation so, there is a need to regulate grid frequency from the load side using distributed energy sources. Novelty: In proposed work, at the distribution side, Electric vehicle has been considered to regulate grid frequency during peak and off-peak hours. Work has been justified by appropriate data and simulated results.
