Abstract

In this study, a new method for designing the damping controller was proposed to improve the transient power system stability in a single machine network connected to an infinite bus. The STATCOM controller problem in a wide area of the system function was considered as an optimization problem with multi-purpose objective function. Also, the Honey Bee Mating Optimization Algorithm was used to determine its parameters. In this paper, a new method for designing a damping controller was presented to improve the transient power system stability in a single machine network connected to an infinite bus. The STATCOM controller design problem in a wide area of system function was considered as an optimization problem with a multi-purpose objective function and the honey bee mating optimization algorithm was used to determine its parameters. As shown, STATCOM improved system stability. For a more comprehensive analysis, the results were tested in three different scenarios. Simulation of the STATCOM controller design for small signal stability was conducted in the MATLAB / SIMULINK environment. The tuning variables in designing the controller were variables c and φ that were used to adjust the modulation index and firing angle of switches. In order to achieve the best possible state, the artificial honey bee colony algorithm was used.
