Abstract

The frequency should be approximately constant in the power system. The secondary control loop is used to maintain the frequency at or near nominal values. This loop is also responsible for maintaining the power exchanged between the control areas connected through connection lines in programmed values. In this paper, the aim is to study and simulate the dynamic behavior of the interconnected power system. Different combinations are considered for the power system. The areas consist of steam, hydro and gas power plants. MATLAB-based simulation studies are presented in two-area and three-area power systems. The simulation results in the time domain are analyzed and investigated by calculating the eigenvalues of the power system matrix in different scenarios. The simulation results show that for the step change in demand load, in the independent areas, the gas power plant has the lowest frequency droop and the hydro power plant has the highest frequency droop.
