GA based Internal Model Controller Design for Load Frequency Control in Power System via Reduced Order Model
نویسنده
چکیده
In the conventional two degree freedom (TDF)-internal model controller (IMC) design, obtaining suitable value of tuning parameter is much more complex and difficult. In this paper, the approach of genetic algorithm (GA) is proposed to obtain optimized value of tuning parameter used in TDF-IMC controller design. For TDF-IMC controller design, 2 nd order reduced-model is obtained using the Routh approximation. The results obtained are quite encouraging and shows the preservation of stability and other dominant/essential characteristics with improved response of load frequency control (LFC) during load disturbances and parameter variations. The applicability of the proposed algorithm is illustrated with the help of a suitable numerical example from literature.

Bayesian Networks (BN) provides a robust probabilistic method of reasoning under uncertainty. They have been successfully applied in a variety of real-world tasks but they have received little attention in the area of load-frequency control (LFC). In practice, LFC systems use proportional-integral controllers. However since these controllers are designed using a linear model, the nonlinearities...

The Microgrid is a small-scale controlled power system, which can be used in islanded mode or in a grid-connected one to provide power. In the islanded Microgrid, the system frequency will be affected severely by the smallest disturbance which can happen due to light inertia in the system. In the independent Microgrid, several generation sources such as solar, wind, and so on can be considered....
