Application-Based Simulations for Diagnosing the Power Quality When Changes in Load’s Power on Each Bus as an Analogy of the Steady-State Stability Phenomena

Abstract

This chapter describes the system’s ability to recover frequency synchronisation across all networks after a gradual change in electric power is determined by simulating the phenomenon of steady-state stability. The simulation is done by choosing and figuring out an analogy of the structure of an electric power network with four connected buses and assuming values for a number of parameters. The objectives for this diagnostic are set on a pair of primary levels, namely, to create the three syntax structures of the programme based on MATLAB and to simulate a phenomenon of steady-state stability based on the programme. The results of the implementation of steady-state stability simulation have been obtained in the form of phenomena such as a reduction of power on bus #1, an addition of power on bus #2, an addition of power on bus #3, and a reduction of power on bus #4. Based on the simulation results, it can be concluded that the MATLAB-based programme is used for the diagnosis of steady-state stability.
