This paper demonstrates the design and implementation of a robust damping controller for damping the low frequency (0.1-2 Hz) electromechanical modes in an interconnected power system. The robust control design is formulated as Hinfin norm optimization problem and the solution is sought numerically using LMIs. This allows additional pole-placement constraints to be imposed to ensure that the time...
The paper describes the implementation of a centralised control-design scheme in a real-time laboratory-based dynamic simulator. A centralised multivariable-control algorithm is designed employing remote feedback signals considering delay in signal transmission. The transmitted signals can be used for multiple-swing-mode damping using a single controller. Such an algorithm is numerically intensive...
A controlled system consists of controller and controlled plant. After a controller has been designed and built, it is essential to conduct closed-loop tests to verify the controller's performance. This obviously requires that the controlled plant be available. For many power system control applications, it is very difficult and costly to build even a prototype of the controlled plant in a laboratory...
