Design of variable-structure load-frequency controller using pole assignment technique
TLDR
In this paper, a variable-structure load-frequency controller for a single-area power system is proposed to enhance the dynamic performance of the integral controller, which is usually designed with the primary aim of zero steady-state error.Abstract:
This paper presents a new technique for designing the variable structure load-frequency controller for a single-area power system. The variable-structure controller effectively enhances the dynamic performance of the integral controller which ia usually designed with the primary aim of zero steady-state error. Further, when the variable-structure system is operated in the so-called sliding mode, the response of the system becomes insensitive to changes in the plant parameters. The control problem is formulated and the results of a simulation study are presented for illustration.read more

An adaptive controller for power system load-frequency control
Ching-Tsai Pan,C. M. Liaw +1 more
Abstract: An adaptive controller is presented for load-frequency control of power systems. It uses a PI (proportional-integral) adaptation to satisfy the hyperstability condition for taking care of the parameter changes of the system. Only the available information on the states and output are required for the control. No explicit parameter identification is needed. The controller can be designed by using a reduced plant model to simplify the design without degrading the performance much, so it is very easy to implement practically. The simulation results indicate that good control performance can be obtained and that the performance is sensitive to the plant parameter changes. The control remains effective in the presence of generation rate constraints. >
